Is colored dark grey dorsal with a light grey belly and darker grey sides and a yellow stripe between the flukes and the dorsal fin.

Coast of New England and the coasts of the UK, Norway, and Greenland
Sharks and killer whales.

Social system/Group size
The group sizes vary with location: around 60 close to the Newfoundland shore, but rather smaller east of Iceland.
The main threat is the entanglement in fishing gear, especially near the coast. They are hunted in Norway, Greenland, Canada and the Faeroe Islands and suffer from the high contentrations of mercury and hexabromocyclododecane in the waters near industrial areas.
At its widest point, this dolphin can be up to 60% of its total length.
