WWF and other organizations campaigned to stop an offshore oil drilling platform from being built in that critically endangered population's habitat. The eastern North Pacific stock of this large baleen whale annually migrates 11,200 miles, roundtrip, between its summer range off Alaska and Siberia and its winter range in Mexico. The gray whale is one of the animal kingdom's great migrators. To keep warm in cold water, Gray whales have a thick layer of insulated blubber as thick as 10 inches. They also “breach” (jumping up into the air then splashing down onto their back or side, known also as cresting or lunging), which is understood to be a form of communication, a form of play, and an attempt at removing skin parasites.

Since they are cetaceans, gray whales have adapted their skills and needs, to develop completely in the aquatic environment. As gray whales are a major contributor to the biophysical diversity and social economics of whale watching in the study area, research that advances our understanding of the spatial-temporal dynamics of habitat use is highly relevant to managing seasonal populations in Clayoquot Sound and throughout the North Pacific range of their coastal migration. The Gray whale is a giant of the ocean, mottled light to dark gray in color and encrusted with barnacles and whale lice. The sperm whale can be found in tropical and temperate oceans, and adult males are sometimes found at higher latitudes. Speak up for species and places through WWF's Action Center.
