Tricks to recognize a Dusky Dolphin
Dusky dolphins are unlikely to be confused with Heaviside’s dolphins but can be easily distinguished from them by their recurved dorsal fin.
1,8 -2m. There’s a little difference in size between the sexes.
Black to dark grey dorsally, prominent whitish blaze on sides of tailstock, white ventrally, whitish grey thoracic patch.
Tall pointed dorsal fin with paler edge. The centrally-placed dorsal fin is erect and hooked. In adult males the fin is more curved, has a broader base and a greater surface area than in adult females.
Narrow and pointy
Short, blunt and dark-tipped beak. The head slopes gently to a small snout, which is well differentiated laterally from the head by shallow grooves but almost imperceptibly in the mid-line.
Fast and active swimmer, highly acrobatic, high jumps. They exhibit some of the most spectacular aerial behaviour of any cetacean in the subregion.
Usually in groups of 20 to 50 individuals.
