We fat all creatures else to fat us, and we fat ourselves for maggots. Your fat king and your lean beggar is but variable service--two dishes, but to one table. That's the end.
Day One

The pig, straight out of the freezer. It seemed to thaw pretty quickly, but you can still see the marks from the freezer shelf on the pig's belly and neck. Look closely at the pig's ear: that's the first fly, making itself busy.

Day Two, Image 1
Pig is discolored, and the face is swollen. Not super smelly yet -- mostly just smells like pig. Flies buzzing around, but not swarming. The life cycle of fly to maggot to fly takes 2-3 weeks, and longer at cooler temperatures.
In summer, a human body in an exposed location can be reduced to just bones in only nine days. Our pig, even though it's much smaller, will take longer since it's not completely exposed to the elements and autumn temperatures in Minnesota limit the amount of insect activity.

Day Two, Image 2

Flies are particularly attracted to the pig's mouth and eyes. That's because most tiny, first-instar larvae eat liquid protein before their mouthparts get big enough to actually eat meat. So blow flies lay their eggs in open wounds (none on our pig) and the moist areas of the nose, mouth, eyes, and anal and genital areas.
Pig, 1:15pm, 9-19-08: It's 76 degrees. There's no wind, there's no precipitation, and the humidity is 48%. Today's high is predicted to be 83 degrees, and it's supposed to be warm and sunny all weekend...Courtesy SMM
that is very rude watching a dead pig rot.RESPECT THE DEAD!
Except that we are learning that, from watching this dead pig rot, the study of decomposing bodies. This might seem rude to you until you realize that when this is applied to a Forensics class allows investigators to analyze and understand the time of death, so that they can solve real crimes and bring closure to the family's of a victim. How rude is that?
Day Two, Image 3
The three big "body clocks" are rigor mortis (the muscle stiffening that happens in the hours after death and then disappears), algor mortis (the cooling of a corpse as it equalizes with its surroundings), and livor mortis (the gradual settling and pooling of blood the begins as soon as the heart stops beating). But these can only widely approximate the time of death, since age, body size, health, manner of death, ambient air temperature, air movement, etc, can all skew the expected changes. 24-28 hours after death, lividity peaks, the body reaches ambient temperature, and rigor disappears. After that, insects are the key. Of course, our piggy was in a freezer for some time, and I'm not sure what to anticipate and when because of that.
After looking at these photos in succession, quickly, I think I'd say that our pig is starting to bloat.
Why? Well, the intestines are packed with bacteria that didn't die with the pig. When alive, the pig's body kept the bacteria in check, but now they're running rampant and breaking down tissue. Also, the pig's own digestive juices and other enzymes are breaking down its body. The decomposing tissues release gasses that distend the abdomen. Eventually, the pressure will also make the tongue stick out and push fluids from the lungs out of the mouth and nose.
But things are just getting going. I don't expect that kind of activity to peak until day 4-6. At least.

I didn't realize the light stayed on. Cool.
@8pm, Friday, 9-19-08: It rained pretty good for a brief period this afternoon (around 6?), but it's dry now. And the pig is under an overhang. It's 74 degrees and calm, with humidity at 51%.Courtesy SMM
Why would you do that to a pig you sick nasty person
yeah, get real, seriously? you WANT to do that? there's things called mental societies for you.
```````agree. stop the needless killing unless it died naturally.
Actually that is exactly how this pig died. We made sure to work with several farmers to find a pig that died of natural causes for this project.
It's called science. they study the efeects of decomposition on pigs, because pigs skin is fairly close to humans, and if they have a dead human, they can compare images with the research from this product. it died naturally and hasa been left alone, untampered with. stop trolling.
I am so glad I found this page! I am very interested in forensics! I am in the process of finishing my Criminal Justice degree right now and I plan to transfer and attend the University of Tennessee for Forensics .I am currently in Early College( It is half high school and the other half college) . I will be graduating with My Criminal Justice degree along with my high school diploma. First though I have to do a senior Project! and I am planning on doing my senior Project on Pig decomposition. I am planning on taking a couple pigs and doing what you have done with the pigs in your photos.
I would love to speak with you , to get a little information on how you began your process.
Thank you !

Everything you never wanted to know about maggots...

We think of maggots as foul, disgusting little vermin, but they actually have some interesting medical uses, along with their value to the law enforcement community. Maggots produce antibacterial compounds that may someday help doctors fight superbugs and can be used to clean and treat problematic wounds.
I like the technical term for that type of problematic wound cleaning: Maggot Debridement Therapy (MDT). Google it!

Oh, my. Things are happening out there just a little more quickly than I thought!

Ok, so I know this is a few years old now, but I just saw it today:
What to say...?? I was intrigued and disgusted all at once! But my burning questions are about the fluid ooze. Of what is it composed? From where did it come? Why and how was it released? Is this a usual occurrence for Day 3 of decomposition?
With all the forensic-based TV shows I watch, I'm surprised this has never come up...
It's normal.
You can read my Day 2 entry [above], but here's the particularly relevant bit:
Day Three, Image 2

All that fluid is attractive to flies, and good for little maggots. There's a lot more fly activity than there was earlier.

Day Three, Image 3

A pig in clothes (yes, forensic entomologists have studied this) will decompose faster than a naked pig because the clothing traps all the moisture against the skin, making it softer and easier for insects to deal with.

@6pm, Saturday, 9-20-08: Ack! I carefully recorded all the weather data, and then I looked at the sticky note, thought it was left over from my previous post, and threw it away. It was an electronic sticky, and it's gone for good. I can approximate, maybe...Courtesy SMM
Weather Underground says that at 7pm it was 72 degrees and clear, with light winds and 52% humidity.
Day Three, Image 5
I was just looking at deathonline.net/decomposition, trying to estimate what we might expect to see tomorrow. I didn't really come up with a timeline (I need to do some Celcius/Fahrenheit conversions, among other things), but I did come across the following description of what's coming:

i'm curious why the fluid under the pig's lower half is so much darker than that under it's torso...
I am betting that's because the fluids under that half of the pig are from its digestive system (intestines), hence the darker color, while the other fluid is probably blood.
maybe there's just a bigger mass of fluids under the lower half?
Thus the color is darker.

why did the pigs fluids after 3 or4 days finaly come out?
i know this is a set up gig, but normally a dead animal (or human) would be found laying in the earth (or at least that's what i imagine in my mind...). so, i'm curious if there are insects from the earth to help with the decomposition process --- that aren't present in this situation - i see that the pig is on a steel plate. or is it all ab out the flies and maggots?
Excellent point. Good question. I am guessing the dermestid beatles that usually show up to eat the flesh will not enter into this scene.
Generally, dermestid beetles don't show up until something's been dead for a while: a few days to a few weeks. They prefer a dried-out carcass, and then they'll eat to the bone. That's what makes them so valuable to taxidermists and museum collectors.
More on dermestids from Science Buzz
And check out our dermestid cam.
Dermestids will be able to get at this pig, the question is will the decomposition be far enough along before it gets too cold for dermestid activity to take place. As Liza mentions, dermestids come after the cadaver is more dried out. This pig is too juicy right now for dermestids. Generally insect activity ceases when the average daily air temperature reaches 50 degrees...
That is a good question.
There's a good discussion of the order in which things usually feed on a corpse at deathonline.net/decomposition. Generally, bacteria and flies are the first colonizers of a body, no matter where it lies.
Beetles generally don't appear in large numbers until the body has dried considerably.
Thanks for sending the link to the deathonline website, Liza. Neat summary. I'd like to point out to folks that while dermestid beetles may prefer beef (or ham, or...) jerky, I've seen them relatively early on in some cases of human decomposition. The adults may sneak in and lay eggs when we're not looking, and then the question becomes, will it stay warm enough for the eggs to hatch into larvae? Those are the hairy ones!
As to WHY the pig is on this pan...we wanted to make sure the pig would not be scavenged by rats or other scavengers so it is in a cage. I learned from our conservation team that if we left it on the grass with just a cage over it that rats would burrow under the cage to get at the pig - hence the pan. We're focused on the entomology and stages of decomposition here, so a rat or other animal absconding with our pig would be a bummer.
In truth, rats and mice can easily get into the cage. Our conservation folks (big shout out to Rebecca!) tell me that a rat can squeeze through a hole the size of a quarter, and a mouse only needs a hole the size of a pencil eraser. The gaps in the mesh walls are bigger than that. But the rodents shouldn't be able to drag off pieces of the pig, and that's what we were trying to prevent.
I don't know...I think a rat would think twice about trying to squeeze through the expanded steel openings - that stuff is sharp!

See that discoloration developing on the pig's belly? (Look back at yesterday's photos to see it start.) I think we're starting to see evidence of putrefaction. The forecast calls for warm and perhaps wet weather all week. That should keep the insects busy...

Since it's hard to see detail from the webcam, I'll go downstairs and get some closeup stills and video each day. (Today is Monday, 9-22-08.)

Oh, friends. Our little piggy doesn't have a face anymore. Also, you can see that bloating has forced the pig's right legs up into the air.
@9:30am, Tuesday, 9-23-08: It's 66 degrees, calm and mostly cloudy (it was raining pretty good just a little bit ago), and the humidity is 90%. Humidity was high overnight (never below 77% percent) and the low temp was 65 degrees.Courtesy SMM
I can't tell whether the maggots go into overdrive at night, or if it just seems that way since I'm not constantly monitoring the cam. I'll have to ask Val Cervenka or Aaron Tarone (our friendly forensic entomologists) about that.
The maggots don't necessarily go into "overdrive" at night, but they keep developing. In the early growth stages, the little maggots form what we call a maggot mass. All those maggots create a lot of heat , which can serve to speed up their development (remember, since flies are cold-blooded, their body temperature is the same as the air temperature) and cause big changes in a short amount of time - like overnight.
i'm curious what influence the rain has?
In general, this would be a good question for Val. Specifically for this pig, it is under a soffit so it is not being rained on.
this is an interesting experiment..... how much time do you think
it will take the pig to fully decompose?
Rain should prevent flies from flying, which means they won't migrate to a corpse while it is raining. In the case of this pig, rain shouldn't have much of an effect if the flies are already there and the pig is covered.
Just like the St. Paul Saints have done for years with their live pig, I think we need to come up with a name for our pig. This year's Saints pig was named Boarack Ohama, which edged out Hillary Rod-ham Clinton, John Muckain in fan voting. Previous Saints pigs have been named Ham Solo, Garrison Squeallor, Bud Squealig, Kevin Bacon, Muddona, Hammy Davis, Jr. and Notorious P.I.G. (Piggy Smalls).
Wilbur gets my vote. Then we need to find a bunch of little spiders.
Man, that's some pig.
Here are the close-up images and video for Tuesday, 9-23-08.
USUAL DISCLAIMER: As with all things dead pig-related, these images are extremely graphic.
That, Liza, is an absolutely fantastic disclaimer.
Day Six, Image 2
It's hard to see in these pictures, since the top half of the pig is the dry half, with the least insect activity, but the decomposition is moving right along.
The pig has developed quite a hernia from all the gas trapped in its abdomen.

There she blows! I thought the break would be in the stomach area.
Me, too.

Friends! The images LIED to us. No, we just misinterpreted. The piggy has not "popped," as Joe put it. We were just seeing some fluid pooling on that back leg.
Here was the surprise image I pulled this morning...
@9:00am, Wednesday, 9-24-08: Surprise! The pig didn't "pop" after all. It was chilly overnight, and it's still cool. 58 degrees and clear, with a light wind and 83% humidity.Courtesy SMM
The cool temperatures might slow things down, but we're supposed to get back into the 70s this afternoon.
If you look at this picture bigger (click on it) you can see something kinda fascinating. There are all kinds of little tracks leading out of the blood pooling behind the pig. I am assuming these are left from the little bugs crawling away from the pig. Hey Val? Is this a common thing that you see at some stage of decomposition? I took some closeup pictures of it earlier today and will post them a little bit later.

Need close ups!
It is just getting more bloated - both back legs now appear to be in the air! Awesome!
I must say, Joe, you really seem to be getting into all this. Do I smell a new vocation? Or is that just 7-day-old pig remains in classic bloat stage?
What are those little bumps across the pig's abdomen? They almost look like nipple wannabees. Somehow I thought things would go much faster -- maybe it's the semi-sterile environment. I have heard that in traditional patriarchal cultures, such as rural Greece and Italy, it used to be the custom for a widow to dig up her husband's body a year after burial. If there was a nice polished skull, she was free to remarry. Otherwise --- back to the ground and wait another year! I wonder how long it will take for Liza's pig to get down to skeleton?
Well, there are a lot of bumps on the pig's abdomen, but I think the bumps you're referring to are nipples. Pigs are mammals, after all, and we've all got 'em.
If we had the pig in full sun, and it were hotter outside, then decomposition might go faster. Also, if we'd wrapped the pig, or dressed it -- anything to trap all that fluid against the pig's skin. But truly, things ARE moving right along.
I tried to find a reference to the burial custom you mention, but I didn't turn anything up. I did find a bunch of other interesting ones, so I'll write more about that tomorrow.
I'm betting that our pig won't get skeletonized. I think it will be too cold before that happens, and the museum's not going to let us leave it around until next summer. But we'll see how far we get before the temperature's consistently at or below 50 degrees.
Val or Aaron: any estimates of what we can expect to see next and when? I know there are formulas you can use, based on weather data, to determine time of death. Are there rules of thumb for looking forward instead of backward?
Here are the day 7 close-ups.
No video, today, Buzzketeers. Sorry. [EDIT: Bryan just told me that he did capture some video today, and I have the movies, but YouTube isn't allowing uploads right now due to site maintenance. Tomorrow, Buzzers, tomorrow...]
Remember: These are graphic images. Viewer discretion is advised.
I added the videos. They're on the Day 7 close-ups page (link above).
Enjoy, but maybe not over lunch?
The blood tracks look like spin art. Are the maggots dragging the blood around and creating those little blood tracks?
Probably. A few years ago we hosted an insect entomology exhibit and a forensic scientist told me of a case where they found a body in a room that was covered in blood droplets. All over the walls, everywhere smatters of dried blood. At first they thought this was evidence of a struggle and a murder, but the case turned out to be a suicide and the tracks were caused by cockroaches.
Those tracks look a lot like the maggot art that Rebecca O'Flaherty does (http://www.maggotart.com/).
Oh, I'd forgotten about maggotart.com! Thanks so much for posting the link!

The Day 4 discussion covered the impact of keeping the pig off the ground in terms of how that may slow decomposition. Couldn't decomposition be accelerated by the nonporous pan retaining all the fluids that those maggots like so much?
Also, will the gas escape only when the maggots emerge through the skin; or can it escape the way it escapes from me after I eat broccoli?
I don't think decomposition is slowed by what the animal happens to be laying on, although that's a good question. It more a question of locality and the microclimate surrounding the remains. The fluids on the pan will dry out, and while adult flies might investigate, they won't be laying eggs in it - not enough substrate. The maggots are feeding mostly on soft tissue. Gas escapes when feeding creates openings in the flesh
As for how it escapes you, I'm not going there.
Can we get a pic of the area around the pig? I wanted to get an idea of the general surroundings - exposure to wind, sun, etc. I've heard mention of the soffitt - but what else is nearby?
IFC, if you didn't see them, the pics you requested are here.
Day Eight, Image 1
Sorry to keep everyone waiting for pig updates today. Some technical difficulties and an overscheduling problem have eaten up most of the day. AND I neglected to note weather data this morning. Anyway...
@10:20am, Thursday, 9-25-08: I neglected to note any weather data when I snapped this one from the feed. But Weather Underground says that at 10am it was 63 degrees and cloudy, with light winds, and 56% humidity.Courtesy SMM
The pig is SO MUCH BIGGER than it was when we started. Now it completely fills the frame. Val, Aaron, how much bigger can it get? Are we close to the next phase of decomposition now?
And it's MUCH stinkier than it has been up 'til now. I think you told Joe, Val, that the smell would be worst at the very end of the bloat stage. Is that right?
To be honest, Liza, I think the smell in the stage of "advanced decomposition" is worse; you know, where more putrefaction is going on. But that's just me. The opinion, I mean, not the smell.
Can we know the upper limits of bloating? It's going to be different with every case, and would depend on factors such as weather, humidity, size of the animal and how quickly flies get going. This is the kind of thing that gets measured at the Anthropology Research Facility at the University of Tennessee, given the quaint name, the "Body Farm." All kinds of data are collected from the human corpses there, to be applied in practical situations where the information is needed to estimate time since death or identify remains, for example.
By the way, you can sign up to donate your remains to the Anthropology Research Facility, but there's a waiting list, so...
That was me Val, above, not Anon. Don't know why that happened.

The holes in the belly are still only "skin deep." But I bet something dramatic happens today. (Is that wishful thinking?)
I know what you mean by dramatic, but I think that pig is full of drama right now!
Day Nine, Image 1
We had to move the piggy a bit, Buzzketeers. Folks on Level 2 could smell it a bit inside the building, and that's no fun. So we've moved the cage. Doing that jostled things around a bit (you can see a sort of "clean" area near the front legs where the movement caused a new burst of fluids), and it means we're now going to see some shadows moving around over the course of the day. Sorry about that.
I didn't pull an early morning image from the feed, either. Apologies again. But here's what it looks like right now.
@11am, Friday, 9-26-08: It's 72 degrees, calm, and clear, with 70% humidity.Courtesy SMM
Forecast high temperature is 85 degrees. Should be interesting...especially now that the pig is exposed to the sun.
One of the things I noticed while moving the cage was the juices that escaped were glistening. Then, on closer inspection, they weren't glistening, they were moving. Crawling with maggots. So yuck. And the smell today was world class. Bryan called it right - you're fine for a while then you get a strong wiff and its gag material.
So, while riding my bike into work this morning, I starting thinking about turkey vultures. We often see them outside the museum, riding the thermals that rise off the river bluffs. They're carrion eaters, and they're exquisitely sensitive to the smell of dead things. Obviously, they can't get into the cage. But I've expected to see them checking it out, or at least circling above, and so far...nothing. Kind of odd, I think.
Day Nine, Image 2
I think the sun and the clear, warm day are speeding things along. If you look closely, you can see maggots moving underneath the tissue-thin layer of skin at the surface. And there are a LOT of tiny maggots turning up on the belly, now, not just in the body's creases.

OK, it's really tough to see, but while John, Roger, and I were outside shooting today's close-up images, the pig's "hernia" popped. It's really tough to see here, but that new cluster of flies is pretty darn excited about the new real estate...
Piggy no longer has a herniaCourtesy SMM
Are you able to take those close-up images without covering your faces or wearing respirators? I checked little piggy out yesterday evening and it was challenging to stay in the vicinity very long. Maybe you all are just tougher than I am, or you've acclimated yourself to the stench with your several-times-a-day visits. Just curious. Oh, and how is this hernia different than the one we humans can get in our abdominal area?
It doesn't smell good, that's for sure. But I find myself getting used to it within seconds. And really, I don't think that standing out by the pig is much worse than standing next to a big dumpster in August. It stinks. And if you breathe in really deep, or you accidentally jiggle the pig, well, it stinks worse. But we aren't covering our faces or breathing through filters.
In theory, the pig's "hernia" is just like a human's. A hernia is the bulging of an organ through the tissue that usually contains it. When most people hear the word, they think of an abdominal or groin hernia, where a weakness in the muscle allows a bit of intestine to poke through. And that's kind of what's happened here: decomposition has weakened the abdominal wall enough to allow organs -- probably intestines -- to pop through.
Thanks for the response Liza. Once I saw your up close hernia pictures my question was answered. That was one nasty hernia. Good thing piggy was dead or that would have hurt like the dickens!
I got my first face to face with the piggy this afternoon, and, yeah, like Liza said, it's not as bad as you'd think.
I think a big part of the smell's grossness is that you know it's coming from a swollen, gooey corpse, crawling in maggots. It's the sort of thing that if you just smelled it while walking down the street you wouldn't be super pleased with it, but it probably wouldn't be unbearable either.

Oh, my.
There's not much left here that's recognizably "pig" besides the little cloven hooves. I guess that pop we saw this afternoon really was the beginning of something much, much bigger. Or maggot-ier, anyway.

Holy cow! What a difference just a few hours makes! I am glad the new location still gets light from the soffit - I can't wait to see if we can pinpoint the frames when this is happening. It is amazing how much work a ton a maggots can do!
At first I had trouble wrapping my head around how such a big change could happen so quickly, Was there a rupture that released all these maggots from the inside?
Day Ten, Image 1
I thought I was impressed yesterday, and I knew that I should expect a change from last night, given how fast things were progressing yesterday, but...wow.

Phoebe, age 5, and Stella, age 3, got to see the pig up-close and in-person early this afternoon. Their report?
Phoebe: "That pig is so nasty."
Stella: "He smells disgusting.
So there you go. The truth, right from the mouths of babes.
I've just joined the Buzz, so I'm coming to this party a little late, but wow, this entire process has been just amazing. And I was genuinely surprised at how quickly Mr. Piggy has liquefied; I literally gasped when I saw the difference between the fourth and fifth Day Nine pictures. Thanks for sharing them with us!
Decomposition: the grossest cool thing EVER.

OK, y'all, I am SO SAD we don't have a public live feed going right now, because I can't even describe what I'm seeing there. There are literally WAVES of maggots swarming all over everything.

I have an early morning game, and so won't be able to post any shots until at least 10. Probably closer to 11. Wonder if there will be anything left to see?

Somehow this morning's first shot isn't as breathtaking as yesterday's last shot. But the maggots stayed busy, and they're super active right now despite the cool temperatures.

Overnight temperatures this week will be in the low 40s, with daytime highs in the low 60s. Wonder if things will slow down again because of the cold?
Do the maggots generate their own heat? Someone told me that when internal temperatures became too hot the maggots would migrate to the surface to cool off.
Maggots don't generate heat the way that, say, people do. That is, they're not "warm-blooded." But once there's a big mass of maggots, they generate heat through friction as they move around. (Bacterial decay can generate heat, too.) And that can complicate time of death calculations.
Maggots do come to the surface to cool off when things get too hot inside.
I would think the chemical reactions of their metabolism would contribute more to the heat generated than friction ( they seem to be well lubricated).
Maybe their chewing generates heat? Thousands of little mandibles... ugh.
I agree, Mr. Factor. And if the maggots didn't crawl in and out of the mass, they would literally cook - the temperature inside the maggot mass can be 20 or more degrees hotter than air temperature. I've been amazed to put a thermometer into a pan full of maggots and see the mercury go to the top.

Wow....can I put dibs on the pig's skin so I can make my own homemade football? This thing is going to be toast before CSI even opens.
Dude, go down there and check the skin out in person—I don't think anyone's going to fight you for it. I don't think anyone's going to fight you for that football, either, so maybe it's not such a bad idea.
Actually, it will make a great football....no one will want to tackle me while I'm carrying it, either.
We knew that decomposition would likely be over, or almost over, by the time the exhibit opened. We had to put the pig out, anyway, because insect activity largely stops once the air temperature is consistently 50 degrees. And that could be any day now.
I'm about to post today's close-ups, but I can tell you this: while it looks, from the top, like the action's all over, there's still plenty of activity going on underneath.
I made my first in-person visit to the pig today and was surprised by how much hair/fur is still on the pig. That really doesn't show up in the photos at all.
aww, broken link :(
who knew searching for "pig" would turn up something so facinating... what a wonderful way to spend a saturday morning
Lett girl
I am just hoping the smell is gone by tomorrow morning! What makes the smell, anyway?
I don't know what makes the smell different, day-by-day. Maybe Val or Aaron can answer that. I do know that most of the stench, generally, is caused by two molecules produced by the breakdown of amino acids: cadaverine and putrescine. Their names about say it all, huh?
Day Twelve, Image 3

Also, here are today's closeups.
So, normally (presuming the pig were not protected by a cage), would other scavengers work away at the skin?
Val can probably give a better answer, but I think so. However, there are also other scavenging insects that would (will?) move in after the maggots—maggots will eat soft, moist flesh, but once a body dries out and becomes tough, a variety of beetles and things show up to chew at the harder tissue.
When the pig was "fresher" or more recently deceased it would have been a target for animal scavengers. In this stage, not so much. In an earlier post Liza was wondering why turkey vultures had not taken an interest in the pig.
I asked a birding friend about the turkey vultures. Here's her response.
"Cool about the pig!
There could be a couple of reasons--turkey vultures will eat food at various stages of decay, but prefer fresher dead foods--perhaps road kill is fresher?
Also, the pig is in a cage and a hard to access area. The amount of people around the museum is probably making them wary."

They're there. They're a very dark brown color right now, which makes them hard to pick out in the photos. Click on an image to see it larger.
I marked some places where you should look closely.
Pig bones: In a few places the bones are visible, but tough to pick out in the photos because of their dark brown color. (If you look at yesterday's closeups, you can see them easily.) I marked up this photo to give you an idea of where to look.Courtesy SMM
EDITED THURSDAY, 10/2: Hey, look at the Day 13 close-ups. (They're not that shocking and disgusting. Honest.) In them, you can easily and clearly see many of the bones. The ribs are still covered by the remaining skin, as are the remaining bones of the skull. But the big bones--the legs, etc--are easy to pick out in the close ups.

I'm still seeing plenty of movement on the webcam, despite the cool temperatures. In fact, if you compare to today's earlier image, there seem to be many, many more maggots. But maybe those are all the maggots that were in the corners of the cage earlier today looking for a warmer place to spend the night?
Fear not, Buzzers. Roger did take close-ups today.

Oh, I miss him already, and he's not even gone.
I've been thinking about our liquifying friend here, and I wonder whether the fact that he was frozen and then thawed made a difference in the rate and type of decomposition. We know that freezing and thawing tissue does real damage -- in plants anyway, it seems to destroy the cells and turn everything to mush.
So maybe the piggy would have taken a lot longer to disappear if he had died in place!
That's interesting.
On the other hand, maybe the freezing/thawing kept the initial insect colonizers from finding the pig right away? Heck, I've seen injured but still very much alive animals already sporting blooms of at least 1st-instar maggots. They find carrion (or soon-to-be-carrion) FAST. But it took a while for us to find clusters of eggs/maggots on the piggy.
Seems like the freezing issue is one that forensic entomologists have had to consider before. Maybe Aaron or Val will weigh in here.
Freezing and thawing can affect those initial colonizers, the blow flies. It's possible that frozen and thawed tissue breaks down in a way that makes it unattractive to them, so that other, later colonizers will be attracted first instead.

Liz,
About the stench. You are right about the amino acid break down- I love those chemical names. Additionally, you have to consider all of the bacteria involved in the decomposition process. They are a source of the gas in the bloat stage, and, since their metabolism is anaerobic, they release all sorts of chemicals, including nitrogen and sulphur based gasses (i.e. ammonia and sulphur dioxide), during this process. Once the bloat stage ends, there should be less of a dominance of anaerobic bacteria and their related smells. In general , changes in bacterial community composition should be occurring throughout the decay process, which should also alter the composition of metabolism products that bacteria produce. As an interesting note: during my PhD, I noticed that replicate jars of the same age could sometimes acquire different smells. Another factor to consider is that once skeletonization has occurred a lot of stinky pig has been converted into relatively unstinky fly biomass. You might want to check with a forensic taphonomist to get better details.

Oh, yeah: close-ups.
Got my first in-person visit with the pig yesterday. Even got to poke at piggy with a stick. The remaining skin is pretty hard and made a hollow knocking sound.
I've seen only a few dead things in my life but lots of fires and I was surprised how much the detritus looks like remnants from burning. The innards look blackened and charred (down to the ridges common in burned wood) and there are wispy bits that remind me of ash.
The maggots writhing in the corner will forever alter the way I view 'snow' on my tv screen. Out of the corner of your eye, the movement is the same.
The smell was still potent when you got up close or when the wind blew at you. It reminded me of something I've smelled before. Something farm/stable-like. Later that evening, I could still catch whiffs of it on my clothes, not a bad smell (I like farms) until you remembered where it came from.
All this talk about smell reminds me of a paper I read once correlating the degree of decomposition with the concentration of ethanol in the body fluids of the deceased. The authors developed this as a way to tell if alcohol in the body was consumed before death or was formed in the body after death.
Anyway, they developed a system to establish "the degree of putrefaction," based on the changes that occur in decompoistion. Point values were given for each change, and the sums were used to define categories of putrefaction: mild, mild to moderate,moderate and severe. The system was known as the SMELLBAD system:
S - skin slippage
M - mummification
E - eyes
L - livid streaks, marbling
L - limpness (rigor)
B - bloating
A - appalling effusions (purging)
D - discoloration

Overnight low temperature was 38 degrees, and it's still a bit nippy out there. Our maggot population seems radically smaller and less wriggly.
Also, Rebecca said we accidentally caught a mouse in one of the sticky traps we put out for the escaping maggots. Bummer. But it makes me wonder if some of the bones that have been moved around were moved by mice instead of maggots?
BTW, the study of what happens to plant or animal remains after the organism dies and before it's recovered is called taphonomy. (The processes of taphonomy include the cause and manner of death, decay, decomposition, transportation, burial, and chemical alterations of the remains.) And rodents and other scavengers are a major cause of bones moving around after a body has decayed.
Correcting myself: Sulphur dioxide would be the result of aerobic processes. Hydrogen sulphide would be a gas produced by an anaerobic process.

I took a look at your close-ups and they're very nice! One thing that struck me when I saw all the pupae - I sure hope you've got the cage far enough from the building so that you don't have hundreds of adult flies finding their way inside as they search out a place to spend the winter...Just saying.

Actually, if you look back at the webcam shots over the last few days, the skin that remains on the pig's torso seems to be slowly, slowly changing color. There's a dark spot spreading from by the pig's back legs and creeping toward the front. Val, what's going on there?

This could be traumatizing for children. This site should be better marked for adults to be aware. We are at the science museum. Mostly kids here.
I'm sorry if you found the pig cam disturbing. That wasn't our intent.
We have tried to let everyone visiting this page know, in advance, what they're seeing, but it doesn't always work.
As a parent, only you know what's appropriate for your child. I've taken my kids, who are 5 and 3, out to look at the pig in person, and they ask to see it on the web. They understand that everything living dies sometime and that decomposition is how our components are recycled. They also think the pig is gross. And that sounds about right to me. I don't think they're traumatized, and I hope other children aren't either.

how come?
Because, my friend, it has gotten cold outside. Most of the pig's decomposition is being driven by insects, and insect activity is greatly reduced or even stopped entirely once the temperature drops below 50 degrees. So the pig might stay like this for a long, long time.
that was very grose and sad poor animails
I Learned something in science that says; an animal that has no exposure to decomposers will eventually mummified. That is if the specimin has been "Deliquified."(that means it has not been saturated in liquid for over an hour)
Lots of things can make a mummy. I was recently at the Mutter Museum where they have a soap mummy.
That is cool where was it!!!
Ps i love your avatar i loved that anime!!!

Is the pig still out there? Is this still being updated? Or has everyone been too distracted with the elections? :-)
Oh, the piggy's still out there. And I'm glad you reminded me. For a while, the temperature was consistently at or below 50 degrees, and decomposition had basically stopped. But it's been warm this week (up until today, anyway) and I should see what's happened...

jus kill the bugs
how long did it take that pig to decompose fully?
The pig is still out in the museum's back yard, actually. It hasn't decomposed fully, and it probably won't for a while now that the weather is cold and likely to stay that way.
But I'm glad you asked, because I'm going to post a new image. (Today is Day Fifty-One.)

4 some reason this reminds me of Lord of the Flies.....
Val,
I was wondering. How often do you get cases where the victim is this badly decomposed? Of those, how often is the case solved?
The time-lapse video is amazing. I especially liked how the vermin kicked it into high gear near the end for the final stretch to Puddleville.
this was so gross and nasty!!!!!!!
god, this is gross!! get a life!!!!
The amount of flies and maggots gives you good reason to never eat anything that a fly has landed on! Just think where that fly originally came from!!
Where oh where are the new close-ups?
You can click on the days listed above for all the close ups that we have now. The pig is cold and frozen these days and doesn't offer up much in the way of interesting photos.
this rocks! waz their really a rotting pig in the science museum ?
There really was. :)
It's actually still out in the back yard, but it's not really rotting right now, what with the cold and all.
`hey so basically you can notice something!!!! :]
omg thats so sad and nasty....why would someone want to watch that?
this is the grosest thing i've ever seeen! i still thinnk its retty ool that u did his and me and my friend wana try it but we DEFINATELY wont. hanxs 4 the great pics!
This is truley amazing! The way that we can track bugs' life spans to solve crimes is breath taking.
So this is what happens during the natural process of decay, but what is something is emballed before it dies, or is stuck in some kind of preservative? I know that the process cannot totally eliminate decay, but how does it interfere and affect subsequent decay?
What a PIG!!!! This is so cool to watch. Love the explosion of the stomach. Glad we came here.
I think it is inhumane to kill animals for "research." Dead human bodies are more accurate because they are the "real thing" and no animal is harmed in the process. Human diseases, accidents, murders, etc. are the true laboratory of science and research.
Just to clarify: this pig died of natural causes. It wasn't killed so it could be the subject of our pig cam or for any other research project.
It's true that human cadaver studies are the gold standard. That's why institutions such as the University of Tennessee's Anthropological Research Facility (the "Body Farm") exist. But human bodies are hard to come by, and pigs are reasonably good stand-ins.
If you'd like to know more about safety testing and other research that often requires the use of human bodies, try Mary Roach's book "Stiff: The Curious Lives of Human Cadavers."
Although this type of research is needed for things like studying crime evidence, studying flight patterns on golf balls with grooves versus dimples is so much less gross. Thank goodness there are people (like Liza) drawn to a variety of professions.
Liza - At what point will this pig's decay be considered complete? No visible bug activity in warm weather? No more significant loss of mass? It seems that 'completely gone' would take many years.
Yeah, and unfortunately, we won't get to find out.
To do the pigcam at all, we made a deal with other groups that take care of and use the outside space here at SMM; that deal included our removal of the pig corpse in the spring before any of those other groups need to use the space. So last week, during a cold snap, JGordon, armed only with a shovel and a trash bag, gave the piggy an unceremonious send-off involving much holding of breath and a dumpster.
It was a good run, though, wasn't it?
AMAZING. I'm soooooooo showing this to my forensics class tommorow <3
Hello! I'm actually doing my thesis on decomposition rates and have had a pig out for 5 months! (Flies JUST started showing up last week!) I've been doing some research and I cant seem to find out one q i have... My carcass is getting little black 'scab-like' defects all over it's body. I've heard this might be blisters from gases, but unlike blisters - you can pick them off....Any ideas?
I think this is great, I wish I would have knew about this when it was going on.I'm writing a paper for a college class on Human Decomposition it can only be 3 pages long. High school teacher as a Prof. for real. Do you have anything to add to your findings of the pig plus I would like to know if I can show your pig to my class if I get this Prof. to ok it.
We'd be happy if you showed your class the video and photos. Unfortunately, the pig itself is completely decomposed and the very last little bits were discarded early this year, so the real thing is unavailable.
where is the cam?
I am now officially a vegetarian
Liza!
I am so happy that I have found this web page! I am in the process of setting up my own little pig farm! I have been inspired by Bill Bass and his body farm that he started at the university on Tennessee ! For my senior project I will be studying decomposition ,and I am going to be using the same process that you have been! I would love to hear your input and I would love your advice as to how I could make this project a success.!
