Dusky dolphin  (Lagenorhynchus obscurus)

Whilst found almost everywhere in the Southern Hemisphere, particularly high concentrations of dusky dolphins are found around New Zealand, Tasmania, southern Australia and south-western Africa. Populations are also found around the western coast of South America, but appear to be separated both geographically and biologically by a gap spanning 1,000 kilometres of Chilean coastline. Individuals to the north of this separation are larger than those to the south, and are sometimes considered separate subspecies (1).

The dusky dolphin is a coastal species, usually found over continental shelves and slopes (2) (3) (6).
