The Gray (or Grey) Whale, Eschrichtius robustus. It reaches a length of about 16 meters (52 ft), a weight of 36 tons and an age of 5060 years. Gray Whales were once called Devil Fish because of their fighting behavior when hunted. The Gray Whale is the sole species in the genus Eschrichtius, which in turn is the sole genus in the family Eschrichtiidae. This animal is descended from the filter-feeding whales that developed at the beginning of the Oligocene, over 30 million years before the present. e Gray Whale is distributed in a eastern North Pacific (American) population and a critically endangered western North Pacific (Asian) population. A third population in the North Atlantic became extinct in the 18th century. The migration route of the Eastern Pacific, or California, Gray Whale is often described as the longest known mammal migration. Beginning in the Bering and Chukchi seas and ending in the warm-water lagoons of Mexico's Baja peninsula, their round trip journey moves them through 12,500 miles of coastline.
