In Real Life
Pacific white-sided dolphins, known for the distinct tri-color pattering that give them their name, are a playful and highly social marine mammal. They are also sometimes known as the “hookfin porpoise” because of their large, curved dorsal fin, though they are not technically porpoises. Though both belong to the toothed whale family, they are separate groups of animals, each including several species. As medium-sized dolphins, these animals can reach up to 400 pounds and 8 feet in length, with males typically being larger than females.
