Right whale dolphin
A dolphin in the genus Lissodelphis, distinguished by a smooth back without a dorsal fin. The genus includes northern and southern species.
Northern right whale dolphin: A North Pacific dolphin species in the genus Lissodelphis, with a black-and-white body and no dorsal fin. This is the northern species in the genus.
North Pacific: The northern part of the Pacific Ocean, extending from the equator to the Arctic. The northern species inhabits this ocean basin.
North Atlantic right whale: A large baleen whale species found in the North Atlantic, with a stocky body and no dorsal fin. Despite the shared name and finless back, it is a whale, not a dolphin.
Lissodelphis borealis: The scientific name of the northern right whale dolphin, a finless dolphin of the North Pacific. This binomial names the northern member of the genus.
Southern right whale dolphin: A Southern Hemisphere dolphin species in the genus Lissodelphis, with a black-and-white body and no dorsal fin. This is the southern species in the genus.
Southern Ocean: The ocean surrounding Antarctica, generally defined as waters south of 60 degrees latitude. The southern species ranges through temperate and subantarctic waters bordering this ocean.
Southern right whale: A large baleen whale species found in the Southern Hemisphere, recognized by callosities on its head. It shares the name and broad region with the southern dolphin but belongs to a different cetacean group.
Lissodelphis peronii: The scientific name of the southern right whale dolphin, a finless dolphin of the Southern Hemisphere. This binomial names the southern member of the genus.
Delphinidae: The family of oceanic dolphins, including killer whales, pilot whales, and bottlenose dolphins. Lissodelphis belongs to this family of toothed whales.
Cetacean echolocation: The use of emitted sound and returning echoes by toothed whales to detect objects and navigate. Sound-based sensing helps dolphins find prey underwater.
