31. Southern Right-whale Dolphin Lissodelphis peroni French: Dauphin de Péron / German: Sidlicher Glattdelfin / Spanish: Delfin sin aleta meridional Other common names: Mealy-mouthed Porpoise, Peron’s Dolphin Taxonomy. Delphinus peronii Lacépede, 1804, “dans les environs du cap sud de la terre de Diémen, et par consequent vers le quarante-quatrime degree de latitude australe [= about 44° S, 141° E, south of Tasmania],” Indian Ocean. This species is monotypic. Distribution. Circumpolar in subantarctic waters, primarily between 30° S and 65° S, including the Great Australian Bight, Tasman Sea, and Chatham Is, but as far N as 25° S in the Malvinas Current, 23° S in the Benguela Current, and 12° S in the Humboldt Current. Descriptive notes. Total length up to 300 cm; weight up to 116 kg. Neonates are thought to be ¢.100 cm long. Like its northern counterpart, the Northern Right-whale Dolphin (L. borealis), the Southern Right-whale Dolphin is torpedo-shaped but slightly more robust, and it has short, broad-based beak; shallow tailstock; small, slender flippers; and no dorsal fin. Skin has distinctive black and white coloring. Most offlanks and belly are white, and black streak runs dorsally from base offlukes along tail before dipping down into more of a cape over thoracic region and melon. Face and beak are white. Flippers are also white but may have dark trailing edge. Edges of flukes on dorsal side are dark gray. Some completely black individuals have occasionally been observed in New Zealand waters. There are 44-49 pairs of conical teeth in each jaw. Habitat. Prefer deep, offshore waters of 1-20°C but may occur closer to shore along coasts off Chile and around New Zealand in water at least 200 m deep. The Southern Right-whale Dolphin appears to be restricted to southern temperate waters and is rarely observed south of the Antarctic Convergence. It may follow cool currents, such as the Humboldt Current, into lower subtropical zones. The Southern Right-whale Dolphin is most abundant off the Chilean coast (where ...
