Scientists have so far been unable to explain why this manta ray, filmed swimming off the coast of Lady Elliot Island on Australia’s Great Barrier Reef, has a pink underside.
It was filmed by Dive instructor Ryan Jeffery two weeks ago and re-posted on the Guardian’s website.
Experts have speculated that the colouration of the male ray may be due to a skin condition.
