The southern bottlenose whale (''Hyperoodon planifrons'') is a species of whale, in the ziphiid family, one of two members of the genus ''Hyperoodon''. Seldom observed and rarely hunted, the southern bottlenose whale is probably the most abundant whale in Antarctic waters. The species was first described by English zoologist William Henry Flower in 1882, based on a water-worn skull from Lewis Island, in the Dampier Archipelago, Western Australia. ==Description== The southern bottlenose whale is fairly rotund and measures in length when physically mature. The melon is extremely bluff. The beak is long and white on males but grey in females. The dorsal fin is relatively small at , set behind the middle of the back, falcate (sickle-shaped), and usually pointed. The back is light-to-mid grey. It has a lighter underside.
