Scientists have found evidence that one of the world's rarest sharks is alive and well, living off the Welsh coast, BBC reported.

Sightings from fishing boats suggest the mysterious angel shark is present in Welsh waters, although no-one knows exactly where.

The shark's only established stronghold is the Canary Islands, where the animals have been filmed on the seabed.

Wales could be a key habitat for the critically endangered shark, which is from an ancient and unique family.
