There are two types of Dall's Porpoise, the Dalli-type and the Truei-type; they differ in their white patch and their distribution. Dalli-type porpoises are found in the northern Pacific Ocean from North America to Asia. Truei-type porpoises are only found around Japan. Both types are found close to land and in the open sea. They may migrate.
