The common seal, named Opal, was “dehydrated and malnourished” when she was discovered on her own and with no sign of her mum on Hunstanton beach on July 9.

Since being rescued, Opal is now being cared for at SEA LIFE Hunstanton’s Rescue Hospital and is showing “remarkable signs of recovery”.

Nigel Croasdale, general manager at SEA LIFE Hunstanton, said: “Stories like Opal’s show exactly why conservation and rehabilitation work matters so much.

“She’s shown real character throughout her recovery, which has been wonderful to see given how vulnerable she was when she arrived.

“We’re all made up with her progress and look forward to seeing her continue to grow stronger, all while seeing more of her sassy little personality along the way.”

Estimated to be six weeks old and weighing just 9.5kg at the time of rescue, Opal was given rehydration treatment and placed under close observation.

She will remain under care until she reaches the target release weight of 25kg.
