A grey seal and her pup have been released back into the wild after "taking a wrong turn" and finding themselves at Wylfa Power Station on Anglesey.
The RSPCA says seals can sometimes get dragged along by the strong currents created by the power station, slipping through the bars at the end of the sea pipe and end up in the cooling chambers.
“We managed to catch the mother and pup who were both healthy" said RSPCA animal collection officer William Galvin.
“We then went to Cemlyn Bay and released the seals. They had a quick sniff of each other and then they were off.”
