The Pacific white-sided dolphin may be observed in large pods (several hundred) and generally reside in the colder waters off the northeastern Pacific. They are also well known for their acrobatic abilities, and will readily interact with boats. Casual obsevers sometimes mistake this animal for the common dolphin. However, Pacific white-sided dolphins have a sloping face, and tiny rostrum unlike the common dolphin.
