Bottlenose dolphin fact sheet



The bottlenose dolphin is the most well-known of all the dolphins. They have a wide distribution throughout coastal and continental shelf waters in tropical and temperate zones.  Bottlenose dolphins are extremely social and often inquisitive animals. They can often be seen lobtailing, breaching, bowriding, and playing with fish, seaweed or other objects. Because of their social behaviour and adaptability they are often kept in captivity. There are currently three recognised species: common bottlenose dolphins (T. truncatus), Indo-Pacific bottlenose dolphins (T. aduncus) and Burrunan bottlenose dolphins (T.australis).

In the Azores, common bottlenose dolphins can be seen year round in the continental shelf waters. They usually form small groups of fewer than 20 individuals and can sometimes be seen with other species.
