Is there a more overlooked creature of the animal kingdom than the narwhal? Granted, it lives in the frosty waters of the Arctic Ocean and has a twisted, mean-looking tusk, but why don’t we give the narwhal more love?

Global climate change researchers are taking note of the odd sea beast. They’ve categorized the narwhal as being the sea creature most at risk from global warming changes. The pronouncement was made following in-depth analysis of how potential environmental problems that could affect the 11 marine animals that live year-round in the Artic region.

Polar bears, which have been generally considered the most “at-risk” animals from global warming, came in second place in the rankings.

Right now there are actually a lot more narwhals in the Arctic region (50,000 to 80,000) than polar bears (20,000). But researchers feel the overall impacts of global warming could have a quicker, more devastating impact on narwhals.

What’s the difference? Adaptability. Polar bears are able to gather food either by swimming or roaming land. As ice sheets diminish, they can forage for food on land.

Narwhals, on the other hand, are highly specialized creatures. A main feeding practice is diving to depths of 6,000 feet to feed on halibut. They live in areas with 99-percent ice cover. If that ice area diminishes, predators like orcas and polar bears will have easier access to getting to narwhals. And warming waters could send the narwhal’s favorite food of halibut to non-icy areas as well.

Following narwhals and polar bears as the most at-risk Arctic animals were the hooded seal, bowhead whale and walrus. Least at-risk are ringed seals and bearded seals according to the study.

BTW: Here’s a little more general information about narwhals:

• They don’t use their tusks for hunting. Males do have “duels” with each other using the tusks to establish dominance. Male tusks can grow up to be 10 feet long. Females grow a much smaller tusk. The tusks are also twisted in a corkscrew fashion.

• An adult narwhal can measure to around 25 feet in length. Males can weigh up to 3,500 pounds while females are about 2,200 pounds.

• The animals also exclusively hunt under thick ice sheets.

• Inuit legends has it that the narwhal was created when a woman holding onto a harpoon had been pulled into the ocean and twisted around the harpoon. The submerged woman was wrapped around a beluga whale on the other end of the harpoon, and that is how the narwhal was created.
