Bottlenose dolphin Tursiops truncatus

The most familiar of the dolphins and the most likely to be seen from British shores, the bottlenose dolphin is found all round the world. In the UK, the best places to see these dolphins are the Moray Firth in Scotland, Cardigan Bay in Wales and the coasts of Cornwall, Devon and Dorset. Bottlenose dolphins are large, fairly plain grey dolphins, darker grey above and paler below. They have a short beak and a large triangular dorsal fin that curves backwards.



Bottlenose dolphins are social animals, usually found in small groups of up to 15 individuals. They are very acrobatic, often jumping out of the water or even doing somersaults. The bottlenose dolphin feeds on fish such as salmon, flatfish, herring, mackerel and cod.
