The gray whale can dive to a depth of 120 meters but generally prefers to many lagoons where it can probe the bottom in search of food. It is a highly migratory whale that lives in cold seas in summer when it restocks its blubber reserves, and winters in the south for the breeding and calving season. Its principal area of reproduction is off the coast of Mexico, but it spends the summer about 10,000 km away, at the edge of the Arctic Ocean.
The grey whale was called ” devil’s whale” by whalers because the female ferociously protected her baby by attacking boats and sometimes breaking them.
