Alaska whales

The North Pacific right whale is a very large, robust baleen whale species that is now extremely rare and endangered. The eastern population of whales that occur off the west coast of Alaska likely has an abundance of only a few tens of animals, making it the most endangered marine mammal population in U.S. waters. Prior to commercial whaling in the North Pacific the populations in the North Pacific probably were over 20,000 animals. Between the late 1960s and the mid-1990s sightings of right whales in the eastern North Pacific were rare, widely scattered, and almost always involved solitary animals. Read more at Alaskan Nature
