The fin whale, also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale. The biggest individual reportedly measured 26–27.3 m (85–90 ft) in length, with a maximum recorded weight of 65.5 to 120 tonnes. The fin whale's body is long, slender, and brownish-gray in color, with a paler underside to appear less conspicuous from below (countershading).
