The dorsal fin is two toned with the trailing edge a much lighter grey. They have a long, light grey patch on their foreside leading to a short, dark grey beak (shorter than in a Common Dolphin). The throat and belly are white and they have a large white Y-shaped patch running from the dorsal fin to the tail. They have a moderately curved dorsal fin.

Zealand, South Africa and South America as three distinct subspecies. They have also been spotted off southern Australia. They breed over summer so females and calves tend to be closer inshore at this time feeding on small schooling fish and returning to deeper water at other times to chase mobile prey. Females reach sexual maturity at around 18 years and breed at three yearly intervals, weaning calves at around 18 months. Climate change will impact on their distribution.

Stranding Information

There have been five stranding events of Dusky Dolphins in Tasmania, usually as a single dead specimen. One specimen was a female giving birth. In New Zealand, Dusky Dolphins have been successfully refloated after mass stranding.
