Wikipedia Abstract

Dall's porpoise (Phocoenoides dalli) is a species of porpoise found only in the North Pacific. It came to worldwide attention in the 1970s when it was disclosed for the first time to the public that salmon fishing trawls were killing thousands of Dall's porpoises and other cetaceans each year by accidentally capturing them in their nets. Dall's porpoise is the only member of the genus Phocoenoides. It was named after American naturalist W. H. Dall.
