Elusive Whales Set New Record for Depth and Length of Dives Among Mammals. A new study of elusive Cuvier's beaked whales shows they can dive to nearly 10,000 feet (3,000 meters). View Images. A Cuvier's beaked whale swims just under the surface of the ocean near the GalÃ¡pagos Islands.
There are about 65 different species of toothed whales. Toothed whales, including all dolphins and porpoises, have teeth, only one blowhole (baleen whales have two) and are generally smaller than most baleen whales. The only toothed whale longer than 13 metres is the sperm whale (they can measure up to 18 metres). Toothed whales are hunters.
