Southern Right Whale Dolphin

Introduction: The graceful southern right whale dolphin, (Lissodelphis peronii), is a small and slender species of mammal found in cool waters of the southern hemisphere. It is one of two species of right whale dolphin, the other (Lissodelphis) is found in deep oceans of the northern hemisphere. It has an unusual appearance for a dolphin, as it is bereft of a dorsal fin, bringing about the 'right whale' into the common name. They are the only dolphin in the southern hemisphere without this feature.

Group sizes vary from a few to 250, although 50 is more of an average sighting. They are often observed with pilot whales and dusky dolphins. Patagonian toothfish are known to prey on southern right whale dolphin, and predators include sharks and the killer whale (Orcinus orca).
