Sea turtle has CT scan to find out why she can't dive

A lost turtle, who can't dive underwater, is being treated by scientists after she washed up in a chilly Welsh beach more than 4,000 miles from home.

Scientists put the turtle called Menai into a CT scanner to try to solve the mystery of why she couldn't sink into the waters.

Now Menai - named after the beach in North Wales where she was washed up - is being nursed back to health ready for being flown back to her home waters off the North African coast.

The female turtle was taken to Anglesey sea zoo after being discovered in the Menai Straits.

But the Zoo's sealife experts were baffled when they found she could not dive in its tank and just kept bobbing on the surface.

So they took Menai on a four-and-a-half journey in a temperature-controlled van to the Royal Veterinary College in Hatfield.

Menai was put into the college's scanner which showed the female turtle was suffering from a lung lesion which was affecting her bouyancy.

The Zoo is now confident they will be able to repair the damage - and remove a build up of gas from her lungs and return the turtle to her home waters in the Atlantic Ocean.

Menai is the first Olive Ridley turtle to be sighted in the UK since records began in 1748.
