Cephalorhynchus genus in the dolphin family Delphinidae .
Extant species
[ edit ]
It consists of four species:
Distribution
Commerson's dolphin
C. commersonii
Argentina including Puerto Deseado, in the Strait of Magellan and around Tierra del Fuego, and near the Falkland Islands, near the Kerguelen Islands in the southern part of the Indian Ocean
Chilean dolphin
C. eutropia
coast of Chile
Heaviside's dolphin
C. heavisidii
coast of northern Namibia at 17°S and as far south as the southern tip of South Africa
Hector's dolphin
C. hectori
coastal regions of New Zealand
The species have similar physical features—they are small, generally playful, blunt-nosed dolphins—but they are found in distinct geographical locations.
A phylogenetic analysis in 2006 indicated the two species traditionally assigned to the genus Lagenorhynchus hourglass dolphin L. cruciger and Peale's dolphin L. australis are actually phylogenetically nested among the species of Cephalorhynchus , and they suggest these two species should be transferred to the genus Cephalorhynchus . Some acoustic and morphological data support this arrangement, at least with respect to Peale's dolphin.[2]
According to a study in 1971, Peale's dolphin and the Cephalorhynchus species are the only dolphins that do not whistle (no acoustic data are available for the hourglass dolphin). Peale's dolphin also shares with several Cephalorhynchus species the possession of a distinct white "armpit" marking behind the pectoral fin.[3]
