Risso’s dolphin — size comparison — facts and sources
Risso’s dolphin occurs in deep waters of warm and temperate seas. It has a substantial, rounded head without a pronounced beak. Numerous pale scars accumulate with age, so older individuals may look almost white.
It hunts chiefly squid, often during nocturnal dives. Fish and crustaceans also occur in its diet. It lives in groups whose members communicate acoustically while travelling and seeking food.
