Risso's Dolphin



A bulky species with a rather bulbous forehead. These dolphins are usually a pale grey colour (right), although this colour fades with age. The skin is fequently marked with extensive pale scars!! Its dorsal fin is relatively long and slender. Very social animals and can create a herd of a hundred or more!!!! Like many dolphins they do ride the waves of boats.

Size: 3.3-3.8m

Young: single calf, born April-September

Diet: squid, octopus, cuttlefish and small fish

Status: scarce, though very locally common.
