Bowhead whales live in the Northern Hemisphere, around pack ice, often in shallow waters. Bowhead whales migrate seasonally within these waters, between summer feeding areas and wintering areas. Bowhead whales are an endangered species .
Bowhead whales are highly vocal and have a large repertoire of calls and songs.
The echoes of these calls may be used to help the whales navigate through the ice as they migrate. As bowheads are baleen whales, they filter their food through their long baleen plates. Bowhead whales open their great mouths and graze along the surface, in the water column, or on the sea floor. Scientists estimate that a bowhead whale needs to eat about 100 metric tons of crustaceans per year. Length of sexual maturity in males is not well documented.
