Sperm whales - Sperm whales are the largest toothed cetacean. The size of most large baleen whales, they actually have teeth on their bottom jaw, used to grasp large squid or fish, unlike other large whales that filter smaller denser prey through their baleen. Almost mythical creatures, sperm whales were historically feared and revered in cultures around the world. The famous 19th century novel, Moby Dick, featured a sperm whale, and was based on the experiences of ‘Yankee whalers’ that roamed the world’s oceans hunting whales from small open boats in the 1800’s. Though not the largest species of whale, it does have the largest head and the largest brain of any animal on the planet; can dive deeper than almost any other marine mammal; and lives in a stable and complex matrilineal society similar to that of elephants. Sperm whales are usually found in deep oceanic waters, but can be observed closer to shore around islands or areas where underwater canyons or a narrow continental shelf provide deep water nearshore habitat.
