The gray (or grey) whale (Eschrichtius robustus) is a baleen (mysticeti) whale that migrates between feeding and breeding grounds yearly. It reaches a length of about m to ft16 a weight of convert36t and lives 50–60 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 Citation neededdate=May 2010. The gray whale is the sole species in the genus Eschrichtius, which in turn is the sole genus in the family (family (biology)) Eschrichtiidae. This mammal descended from filter-feeding whales that developed at the beginning of the Oligocene, over 30 million years ago.
The gray whale is distributed in an eastern North Pacific (American) population and a critically endangered western North Pacific (Asian) population. North Atlantic populations were understood to have become extinct in the 18th century. However, on May 8th, 2010, a sighting of a gray whale was confirmed off the coast of Israel in the Mediterranean Sea, leading some scientists to think they might be repopulating old breeding grounds that have not been used for centuries. Another gray whale, believed to be the same spotted earlier off the coast of Israel, was spotted on 8 June off Barcelona.
