A dolphin has died after a group of the animals became stranded on a beach in Wales.
Six dolphins were stuck at Valley on the island of Anglesey in North Wales on Wednesday.
A team of marine mammal medics was dispatched to Valley to provide first aid to the common dolphins, according to British Divers Marine Life Rescue (BDMLR).
The medics found most of the group – of four adults and two juveniles – to be in good health, but one of the adults, which had an old healed wound where it had lost a dorsal fin, appeared to struggle when it started swimming again.
There was concern the other dolphins might become stranded again so some of the medics entered the water to help redirect them.
Most of the group refloated thanks to the incoming tide.
Volunteers monitored the pod but two of the dolphins disappeared in the early afternoon during high tide.
One of the dolphins was found deceased in Anglesey on Thursday morning, BDMLR confirmed.
The dolphin found dead on Thursday morning was one of the pair that disappeared, BDMLR added.
A post-mortem examination will be carried out and team members will stay on site in case more dolphins find themselves in difficulty.
Cemaes Bay Coastguard said it had helped volunteers from BDMLR during the efforts to save the animals.
