Relatively large head with a short body and flippers

The most widely distributed pinniped; haul out onto rocky shores, mud flats, sandy beaches, and log booms; may also inhabit fresh water; do not tend to travel more than 20km from the shore

Courtship and mating take place underwater. Females give birth to a single pup. Pup is born in an advanced state of development, and can crawl and swim within a few hours of birth. Mother will mate again immediately after weaning.
There are no current population estimates for Pacific white-sided dolphins. In the early 1990s it was estimated that their entire population consisted of 1,000,000 individuals and the most recent survey in BC, which was published in 2007, estimated that 25,000 individuals live in BC waters.
Are not endangered, although their tendency to stay in the same area for the majority of the year has meant that some local populations have disappeared, such as in the Gulf of Alaska.
