A dolphin which was seen playfully joining a group of swimmers in Dorset has been injured by a boat propeller.
Lynda MacDonald, 50, and her partner, son and his girlfriend were joined by the bottlenose dolphin on their morning swim in Lyme Bay, Dorset on August 3.
A video showed the playful mammal dancing across the water in a vertical position asking for belly rubs and guiding people across the water with its beak.
However the friendly dolphin has since been injured by a boat in the Lyme Bay area, as wildlife experts began to fear for its safety.
An urgent warning has now been issued to swimmers to stay away from the creatures, as it can lead the animals to let their guard down.
