Grey whales undertake the longest annual migration of any known mammal, along the coastlines between their summer feeding and winter breeding grounds. Belonging to the baleen whale group, they have plates for filtering marine worms and crustaceans from the ocean floor. Grey whales are split into two separate populations, the eastern North Pacific (American) and the critically endangered western North Pacific (Asian) population. They are the only species in their genus, which in turn, is the only genus in the family.
