Bottlenose Dolphin

(Tursiops truncatus)

Bottlenose Dolphins in British waters are the biggest of their kind – they need to be able to cope with our chilly waters! They are very sociable and will happily swim alongside boats, providing people on the boat a wonderful wildlife experience.

Overview

Bottlenose Dolphins are the most familiar of our dolphins and most likely seen from British shores. These dolphins are the biggest Bottlenose Dolphins in the world – their size helps them cope with our chilly waters.

Bottlenose Dolphins are very social animals and can often be seen in small groups of up to 15 individuals. They love to jump out of the water and will happily approach boats to bowride (surfing in the waves created by the boat). They feed on fish, often working as a team to hunt.

Key Facts

  • A chunky, fairly plain grey dolphin, darker above and paler below. Their beak is short and stubby and their dorsal fin is large, sickle-shaped and often marked with notches and scratches. Bottlenose Dolphins are often sighted close to shore alone or in small groups. Look out for boisterous splashing and breaching – and don’t be surprised if they approach your boat to check you out!
  • Individual Bottlenose Dolphins can be recognised from the unique pattern of nicks and notches on their dorsal fin – a bit like a fingerprint! Dolphins can then be tracked over their lifetime using only photos of their fins.
  • Length: up to 4m Weight: 500kg Average Lifespan: 45-50 years
