Four grey seals have been released into the sea after being nursed back to health at the Welsh Mountain Zoo at Colwyn Bay.
The seals had been washed ashore on the Isle of Man and were then flown to the zoo by private jet at the end of last year.
They were released into the waters at Penrhyn Bay, Llandudno, on Sunday.
Another pup, found on the beach at Prestatyn, is still being cared for at the zoo.
Joanne Roberts, from the zoo, said everyone was pleased to see the pups rehabilitated and back in the wild.
"People were happy more than anything to see them go - to see they have reached their target weight.
"The seals are back in full health and we have been able to get them back out into the wild".
The four pups, which had been fed with herring, were given the names Mango Chutney, Vindaloo, Kashmir and Halleem by staff.
They were separated in pairs and they had their own indoor and outdoor pools at the special unit.
The zoo, which specialises in nursing seals back to health, took delivery of the seals at the end of October and at the beginning of December.
Its seal rescue centre, which opened in 1997, has two filtered pools and an indoor intensive care unit.
Ms Roberts added: "A few of the seal were bloodied, we have just been caring for them and trying to fatten them up because they had to reach a certain weight".
