Trawlermen have landed an albino ray thought to be the first found in British waters.

The 80cm-long fish was caught in the Solent and is now being cared for at the Blue Reef Aquarium in Portsmouth.

Experts are surprised that the ray survived so long without camouflage to hide from predators.

They have nicknamed him Gamma Ray because the lack of markings mean it is difficult to determine accurately which species he is.

Robbie Robinson, the aquarium's curator, said: "Gamma Ray would have stuck out like a sore thumb on the sea bed."
