The National Marine Aquarium in Plymouth has become the only UK aquarium to display Spotted Eagle Rays.
The six Spotted Eagle Rays have moved into their new home in the coral seas tank. The species is distributed worldwide in tropical and warm temperate waters.
The creatures - which can live for 25 years - grow up to two metres in wing span.
They have been in quarantine for two months and it is planned that they will become part of a captive breeding programme.
Senior biologist James Wright said they have had to re-train the creatures in their feeding habits.
James Wright said: "We firstly taught them to take food from the bottom of the tank, then we put on a light at the top of the tank each time we introduced food. They began to associate the light with food." http://www.national-aquarium.co.uk/
