The back of the dolphin is dark grey or black and dorsal fin
is distinctively two-toned—the leading edge matches the back in
colour, but the trailing edge is a much lighter greyish white.
Duskies have a long, light grey patch on their foreside leading to
a short, dark grey beak. The throat and belly are white.
There are two blazes of white colour running back on the body
from the dorsal fin to the tail. Right between the white areas
remains a characteristic thorn-shaped patch of dark colour,
by which the species can easily be recognized.
