Dall's Porpoise

(Phocoenoides dalli)

The Dall's porpoise may be more bulky than most small cetaceans but swims so fast that she makes a big spray every time she surfaces to breathe. Many other porpoise species also have bold and beautiful patterns of black and white, and some have other colors as well. Porpoises communicate with sounds that are usually well above human hearing.
