The species is fairly rotund and measure 9.8 metres (32 ft) in length when physically mature,and there have been claims that large individuals reach up to 11.2 metres (37 ft),rivaling Giant Beaked Whales and being significantly larger than known records of the subspecies in southern hemisphere and the close-resembling tropical species.The melon is extremely bluff.The beak is long and white on males but grey on females.The dorsal fin is relatively small at 30–38 centimetres (12–15 in) and set far back on their bodies.It is falcate (sickle-shaped) and usually pointed.The back is mid-to-dark grey.They have a lighter underside. Weight estimates are hard to come by.For the northern bottlenose whale,5,800–7,500 kilograms (12,800–16,500 lb) is given somewhat consistently.
