Porpoises and dolphins are often confused with each other in English translations of Native
American mythology. The "Dolphin Clan" and "dolphin crest" of the Tlingit and other coastal
Alaskan tribes are actually Dall's porpoises, for example. (Some dolphins, like the striped
dolphin, do live as far north as Alaska, but the Tlingit have a different name for them.)
Like whales, porpoises were hunted for food by skilled canoe hunters
in many Northwest Coast tribes, and were often considered Dolphins
and porpoises are closely related to each other, and in some tribes
of the California coast, the same word is used to refer to both kinds of animals.
In any case, Native American tribes living near the oceans, like coastal cultures all over the world,
have many stories about porpoises and dolphins helping people by carrying them to shore in rough
waters or driving away menacing sharks. Porpoise are also occasionally used as a clan crest or
totem in Northwestern tribes, such as the Tlingit Porpoise Clan, called Chookaneidi or
Chukanedi in Tlingit. Porpoise can sometimes be found carved on totem poles in these cultures.
