High Quality Content by WIKIPEDIA articles! Dall's Porpoise is a species of porpoise found on the North Pacific. It came to worldwide attention in the 1970s when was disclosed for the first time to the public that salmon fishing trawls were killing thousands of Dall's Porpoise and other cetaceans each year by accidentally capturing them in their nets. The Dall's Porpoise is the only member of the Phocoenoides genus. It was named after American naturalist W.H. Dall. The unique body shape of the Dall's Porpoise makes it easily distinguishable from other cetacean species. The animal has a very thick body and a small head. The colouration is rather like that of an Orca— the main body of the porpoise is very dark grey to black with very demarcated white patches on the flank that begin some way behind the flippers, which are small and close to the head.
