The IUCN lists Commerson's dolphin as Least Concern in its Red List of Threatened Species. The proximity of the dolphin to the shore makes accidental killing in gillnets a common occurrence. The dolphin was killed for use as crab bait by some Argentinian and Chilean fishermen in the 1970s and 1980s, but this practice has since been curtailed. [2]
Shown is the northern species, so the only white parts are the bellies, hidden from this angle. Both species are highly gregarious. They move in pods of several hundred individuals and sometimes congregate in groups of 3000. [2] The groups may also contain dusky dolphins and pilot whales (in the south) and Pacific white-sided dolphins (in the ...
The long-finned pilot whale (Globicephala melas) is a very large dolphin, measuring five to six meters long and weighing one to three tons.

[4] [5] Its body is nearly all-black with a white ventral marking, extending forward as a narrow band from the caudal peduncle to
[10] [11] More extensive anomalous pigmentation has been observed, with records of pure all-white individuals, [12] [13] as well as melanistic (all-black) individuals. [ 14 ] [ 15 ] In 1998, a potential hybrid of a southern right whale dolphin and a dusky dolphin ( Lagenorhynchus obscurus ) was observed and subsequently described in 2002.
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
The dusky dolphin has a distinctive colouration that resembles the Pacific white-sided dolphin. It has a dark grey or black upper area, light grey face, chest area, and flank patch, and a white underside. The flank patch has a branch that extends over the back and can reach the blowhole.
