A rare tropical turtle remains in a serious condition and is "lucky to be alive" after being washed on to an Anglesey beach.

The animal could be an Olive ridley turtle - the first ever to be seen in the UK.

It was discovered at Tan-y-Foel on Saturday close to Anglesey Sea Zoo and staff took it to a vet.

The turtle, believed to be female, has been nicknamed Menai and is undergoing rehabilitation.
