Manx Whale and Dolphin Watch has shared a video of a white Risso's dolphin, swimming near Marine Drive.
The Peel based charity says Risso's dolphins return to Manx waters every year in March and stay until September.
The dolphin was filmed by Manuela Swiatek and who sent it to the charity.
It adds the mammal is very white due to scarring from fighting with squid, octopus and other Risso's dolphins.
