Tucker the gassy sea turtle treated for the bends so he can dive

Rescued olive ridley sea turtle is too buoyant to be able to dive for food but experts hope to change that with decompression treatment

Vets have put a rescued sea turtle into a hyperbaric chamber, usually used to treat human divers suffering the bends, in a bid to remove gas bubbles in its body that stop it diving.

Experts from Seattle will test the buoyancy of Tucker the 20-year-old endangered olive ridley sea turtle on Friday in the hope that they can one day release him back into the ocean.
