Very large dolphins, up to 3 metres long and 354 kilograms.


With the onset of winter cold, they begin to migrate to warmer waters to spend the winter in more comfortable conditions. Often migrate with other members of the family.

The movements of these dolphins are fast and energetic, jumping high and often out of the water.

White-beaked dolphins like to accompany passing ships.

Food and feeding habits

It feeds mainly on demersal and benthic fish (cod, herring, flounder, navaga, capelin, merganser) and less commonly on crustaceans and molluscs.
