One of the most poorly known dolphins and also amongst the smallest (2) (5), Heaviside's dolphin has a blunt head, rounded, paddle-like flippers (2), and bold markings. The front half of the stocky body is grey and the rear half is largely bluish-black. The flippers are dark and dark patches encircle the eyes and blowhole. The underside is white, as are the 'armpits' behind the flippers, and a distinct white finger-shaped marking extends from the belly along each flank (5) (6).
