Commerson's Dolphin

Open encyclopedia reference

Commerson's dolphin (Cephalorhynchus commersonii) is also referred to by the common names jacobita, skunk dolphin, piebald dolphin, panda dolphin, or tonina overa (in South America). It is a small oceanic dolphin of the genus Cephalorhynchus. Commerson's dolphin has two geographically isolated but locally common subspecies. The principal subspecies, C.c.commersonii, has sharply-delineated black-and-white patterning and is found around the tip of South America. The secondary subspecies, C.c.kerguelenensis, is larger than C.c.commersonii, has a less-sharply delineated dark and light grey patterning with a white ventral band, and is found around the Kerguelen Islands in the Indian Ocean.

The dolphin is named after French naturalist Dr. Philibert Commerson, who first described them in 1767 after sighting them in the Strait of Magellan.
