Center for Biological Diversity petitioned U.S. Fish and Wildlife Service to list Pacific Walrus as a threatened species because of diminished sea ice brought on by climate warming. Pacific walrus prefers sea ice for moulting, mating, nursing and resting between dives for food. Pacific walrus males grow to 12 feet long and up to 1,815 kg. Females reach half that weight. Walruses dive and use sensitive whiskers to find clams and snails in dim light on the seafloor.
Fish and Wildlife Service said that inaccessibility protected walruses for decades, but a rapid decline in summer sea ice has made them vulnerable. In the Chukchi Sea between Alaska and Russia, where Pacific walrus females and juveniles spend their summer, ice could be absent during that season by 2060 or sooner.
