Gray Whales visit Puget Sound

When people hear of Puget Sound, they often think of Orcas, but we also have many other different types of whales that stop by Puget Sound throughout the year. One of these is the Gray whales. A small sub set of Gray whales come to Puget Sound each spring to feed on Ghost shrimp in the waters near the south end of Whidbey Island.

Gray whales can grow up to 50 feet in length and weigh 40 tons, or about the weight of 20 average US cars. They have one of the the longest migrations of any animal, traveling between their birthing lagoons in Baja California and their summer feeding grounds in the Bering Sea. Gray whales feed by scooping up mud on the bottom of the ocean and using their baleen to filter out small invertebrates. They primarily feed on Crustaceans such as crabs, lobsters, crayfish, krill, barnacles, and, of course, Ghost shrimp.

The Gray whale (Eschrichtius robustus) are in the order Cetacea, which includes Whales, Dolphins, and Porpoises. The North Pacific population is estimated to be between 20,000 and 22,000. Gray whales can be seen along the west coast of the United States as they migrate from their birthing lagoons in Mexico to summer feeding grounds near Alaska.
