There are two species of porpoise that occur within the Salish Sea. Harbor porpoise (Phocoena phocoena) are the smaller of the two species, considered to be shy, with surface behavior characterized by slow surface rolls (Figure 1). Dall’s porpoise (Phocenoides dalli) are larger, and as one of the fastest cetaceans, their surface behavior usually produces rooster tails (Figure 2). Dall’s habitat is generally farther offshore than that of the harbor porpoise.
