The gray whale (Eschrichtius robustus), also known as the grey whale, gray back whale, Pacific gray whale, or California gray whale is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters, a weight of 36 tonnes, and lives between 55 and 70 years. The common name of the whale comes from the gray patches and white mottling on its dark skin. Gray whales were once called devil fish because of their fighting behavior when hunted. The gray whale is the sole living species in the genus Eschrichtius, which in turn is the sole living genus in the family Eschrichtiidae. Order: Artiodactyla, Infraorder: Cetacea, Family: Eschrichtiidae, Genus: Eschrichtius, Species: Eschrichtius robustus Lilljeborg, 1861.
