Katherine Rundell wrote for the London Review of Books that "The narwhal is exquisitely formed."

"To conserve heat, the surface area of its skin is as streamlined as possible: no ears, no lips, no eyelashes, no inconveniently extruding sexual organs; nothing to hold back the swift passage through water," she wrote.

In 1969, for a few brief days, New York Aquarium had the only captive narwhal in the world, named Umiak.

The narwhal was flown 2,650 miles in a "dramatic jet flight," according to Life Magazine, to Coney Island, after it was found following the hunters who killed its mother, the Indiana Herald reported.

To keep it happy, the aquarium provided Umiak with a white whale as a substitute mother, according to the New York Times, but, alas, it wasn't enough.

Narwhal tusks can grow as thick as a lamppost and as a tall a man, according to Smithsonian Magazine. But they're not traditional tusks.

They're actually teeth that grow rampantly until they pierce through the upper left of the whale's mouth, according to Canadian Wildlife Magazine, and continue growing up to 10 feet. Unlike elephants or walruses, their task grows straight.

When Nweeia saw his first, he saw a dozen. He was sitting on an ice floe in the middle of the night.

He told NPR, "It was as if you had gone to some grand party where you were invisible. I felt like I shouldn't even talk or say anything or move just because I felt that if they somehow knew I had broken their trust that my opportunity would be gone."

They discovered the tusks have about 10 million nerve endings along the surface, which they rub together to communicate," the New York Times reported.

The tooth is almost inside-out. The sensitive nerves on the outside act as an antenna to sense prey and sea conditions. They can even detect air pressure.

"You can think of it as a weather station," Nweeisa told NPR.

There were three kinds, according to the New Yorker. They make clicking and buzzing noises for navigation and for catching cod and shrimp. The sounds are helpful when they're hunting in deep, dark waters.

The third type of noise is calling, which is how they talk to each other — it involves whistles, sonic pulses, and clicks.

Climate change is their greatest threat since narwhals rely on their ice habitat. It's a place to feed and find refuge, especially from predators like orca whales.

According to the London Review of Books, if the ice melts, there will be nowhere to hide and nowhere to feed.
