Habitat and Distribution:
There once was 3 gray whale populations. The most familiar is the population in the eastern north Pacific - the whale commonly known as the California gray whale. These whales range from breeding/calving grounds off Baja California, Mexico, to feeding grounds in Northern California, the Gulf of Alaska, and the Bering and Chukchi Seas off Alaska. There is also a Western North Pacific (or Korean) gray whale stock found off the coast of eastern Asia, which is now very depleted, numbering only about 130 animals. The 3rd population is a North Atlantic population, which is now extinct.
'Flex,' a satellite-tagged western gray whale stirred interest from scientists when he traveled over 5,000 miles over 124 days in a trip from Russia to Oregon in fall-winter 2011. Photo-identification work revealed that Flex was also seen off Vancouver Island in Canada in 2008, and at that time, was thought to be a whale from the California gray whale population.
