Norwhal

The name narwhal means “corpse whale” in Old Norse. Narwhals live in the deep cold waters of the high Arctic. A close relation of the beluga, narwhals have only two teeth, both in the upper jaw. The left tooth of the adult male looks like a tusk and grows up to 3 m (about 10 ft) long, spiraling counterclockwise out of the male’s head. Narwhals socialize in small pods of about 12 animals that are part of larger herds. They migrate seasonally as the ice edge moves. Fish, squid, and shrimp make up their diet.
