A SEAL pup released by Cornish Seal Sanctuary in Gweek has been found dead on a beach near Bournemouth with serious facial injuries - it is thought she was struck by a jet ski.

Sponge Bobby, a six month old female grey seal, was released from the Cornish seal sanctuary last month.

Conservation experts traced the animal using the identification tag on its flipper after she was discovered at Hengistbury Head on Monday.

Wildlife photographer and environmental campaigner Steve Trewhella, of UK Coastal Wildlife, said the animal had suffered serious injuries to its face, believed to have been caused by a boat or jet-ski.

Urging people to keep their distance from seals, as well as other sea animals, he added: “They are wonderful creatures – watch them, film them and enjoy the spectacle but you have to respect the fact that they are vulnerable animals.”

Emma Rance, marine conservation officer at Dorset Wildlife Trust, said the animal had sustained severe head injuries.

She said: “She had suffered a lot of trauma to the head area and we assume that is the reason for her death.

“It’s quite likely she would have been hit by a propeller.
