About

A social species of dolphin, usually found in pods of 5-10 individuals in UK seas; though much larger groups can be seen elsewhere in their range. Like most species of dolphin they are incredibly acrobatic and will often approach boats to bowride. White-beaked dolphins are a subpolar species, common in the cooler waters of the North Atlantic. A small population is found year-round in Lyme Bay, Devon/Dorset and dolphins are spotted close to shore in Northumberland in the summer months. White-beaked Dolphins feed on fish and work together to herd large schools.

How to identify

A large, stocky dolphin with a distinctive white beak. They are black in colour, with a lighter underbelly. A white flash on its sides and back help differentiate from other dolphins. They have a tall curved dorsal fin.

Distribution

The cold temperate waters of the continental shelf and open waters of the North Atlantic Ocean. Nationally, populations of white-beaked dolphins can regularly be found in Lyme Bay, around the Hebrides and seasonally off the North East England coast.

Did you know?

White-beaked Dolphins are often sighted with young calves during the summer months in both Lyme Bay and off Northumberland, suggesting these may be important nursery areas.

How people can help

Report your White-beaked Dolphin sightings to your local Wildlife Trust. If you spot White-Beaked Dolphins whilst at sea, maintain a distance of at least 100m, especially if a calf is present. If the dolphins approach you, maintain a constant speed and allow them to interact on their own terms and leave at will. If you find a stranded White-beaked Dolphin (dead or alive), please report it to the relevant authority (see www.wildlifetrusts.org/living-seas/marine-protected-areas/sightings). The Wildlife Trusts are calling for a Marine Conservation Zone (MCZ) to protect the White-beaked Dolphin population in Lyme Bay.
