Slate grey with white patches, these whales have a tail fin to push them through the water.
At fifty-two feet and thirty-six tons, gray whales are enormous sea-dwelling mammals. Living to be fifty years old or more, these whales journey between eating and breeding. Grey whales feed on crustaceans and other organisms living on the ocean floor. Before winter, gray whales begin a six thousand mile migration to Baja California where mating occurs. They return home at a pace of eighty miles per day, the longest annual migration of any mammal. On their way, whales communicate to each other through loud whale song and must breathe through their blowholes on the top of their head. Unlike most mammals, whales must breathe consciously.
Fun Facts: Grey whales sleep with one eye closed.
