The Natural History of Dall’s Porpoise in the North Pacific Ocean

  • G. Victor Morejohn

Abstract

Dall’s porpoise, Phocoenoides dalli (True), is commonly encountered over the continental shelf of North America and in offshore and pelagic waters of the western and eastern North Pacific Ocean. This striking black and white porpoise is characterized by great speed and a cone-shaped splash it makes when surfacing to breathe. Because of its great speed in the wild, making it extremely difficult to capture alive, and its hyperactivity resulting in high mortality after capture, much important information remains to be disclosed of the basic components of its life cycle.
