A porpoise has been successfully rescued from a beach in Guernsey.
Dolphins have been known to attack porpoises
A bather spotted the animal floundering on Perelle beach on the island's west coast on Thursday evening.
The rescue operation was co-ordinated by the GSPCA, and was helped by the inshore rescue boat and some members of the public.
The porpoise, which did not appear to be injured, was given an antibiotic injection by the GSPCA's vet. It was then taken back out to sea.
Geoff George, an animal collection officer and marine medic for the GSPCA, says the porpoise may have had a problem with its natural navigation system, or it could have been scared by a pod of dolphins.
Dolphins have been known to attack and kill porpoises.
Mr George says it took more than one attempt to release the porpoise.
He said: "Some members of the public had already tried to take the animal back out to sea a couple of times, but it kept re-beaching.
"They were brilliant. They wouldn't give up, even though they didn't have any waterproofs.
"Eventually, we used the inshore rescue boat to take the porpoise back into deep water."
Having been assessed as fit to be released, Mr George says if the porpoise had kept re-beaching, it would have had to have been put to sleep.
He said: "I'd like to thank everyone who helped make it a successful rescue.
"Euthanasia is the very last thing we ever want to do."
