Commerson’s dolphin

Scientific name: Cephalorhynchus commersonii  

Home: Commerson’s dolphin lives in the southern coast of South America-  Argentina, the Strait of Magellan and near the Falkland Islands- and near the Kerguelen Islands in the Indian ocean. Unfortunately, Commerson’s dolphin lives very close to shore so it often gets tangled in fishing nets and gear in coastal areas.

Physical Features: Commerson’s dolphin is a super cute, black and white dolphin: Its head, front fins, dorsal fin, and fluke are black; It’s body and front side are white. These dolphins are very small and only grow to around 5 ft in length. The smallest dolphin ever known was a 4.5 ft, 51 lb female found in Patagonia.

Commerson’s dolphin is said to resemble a Porpoise more so than a typical dolphin but its behavior is dolphin-esque none the less!The sexes are distinguished by a black spot on their bellies- females have a round spot and males have a tear-drop shaped spot.

Food: They are active predators and eat a wide array of sea food. They mainly feed on small fish as well as invertebrates such as krill, squid, cuttlefish, crab, shrimp, and squid.

Conservation Status: Not much is known about the Commerson’s dolphin’s conservation status and it is listed as “Data Deficient” on the IUCN’s Red List of Threatened Species. However, it has the most abundant populations of the genus Cephalorhynchus.

Fun Facts:

- Commerson’s dolphin is named after Philibert Commerson who first described them in 1767 after spotting them in the Strait of Magellan
