The Grey Whale is a medium to large-sized baleen whale (baleen is a flexible material found in long, thin plates along the jaw which act to filter small food particles rather than using regular teeth). It has a streamlined body and narrow, tapered head. It has dark grey mottled skin, often covered with patches of barnacles and crustaceans. This whale does not have a dorsal fin but has a low hump and a series of seven to fifteen “knuckles” along its dorsal ridge. Two to four grooves on the underside of the throat allow the whale to extend its throat so it can feed by scooping up bottom sediment and straining it through its baleen.
Weight: 22 to 38 t (24 to 42 tons). Length: Females, 12 to 15 m (39 to 50 ft); Males, 11 to 14 m (36 to 46 ft).
