An ultra-rare pink manta ray — maybe the only one in the world — has been photographed during a dive on the Great Barrier Reef.
Scientists don’t know why the manta is pink, but have ruled out an odd diet or illness.
Australian-based photographer Kristian Laine took the photographs during a dive just off Lady Elliot Island, northeast of Bundaberg, Queensland.
The ray, which measures 3.3m across, is nicknamed Inspector Clouseau after the famous fictional detective character from the Pink Panther films.
“I had never even heard of a pink manta,” said Mr Laine, speaking to ScienceAlert.
“And when I first saw it, I thought my camera was playing up.
“Only later that night I saw a photo of a pink manta on the restaurant’s notice board and thought it was a joke.
“Until I rushed to check the belly patterns in my camera.”
This isn’t the first time the pink ray has been spotted.
It was first seen five years ago and was photographed in 2015 by diver Ryan Jeffery.
The pink manta has only been seen around 10 times, according to National Geographic.
But scientists are still trying to investigate the strange creature and understand more about its origins.
Scientists collected a small biopsy — a sample of living tissue such as skin — from the manta in 2016 to try to explain the bright pink colour.
“There has not been a thorough investigation into diet or stable isotope analysis,” said Asia Armstrong, of Project Manta, which has been studying Inspector Clouseau.
Testing called stable isotope analysis shows what is present in a sample, such as minerals*, hormones* or other substances that could cause the colour.
“But given the stability* of the white “birthmark” and pink colour over time we think diet can be ruled out.
“The working theory is that it is just a different and very unique expression of the melanin*, but that is still to be confirmed.”

Manta rays are the world’s largest rays and are considered vulnerable.
There are two species, the giant oceanic manta ray (up to 7m wingspan) and the reef manta ray (up to 5m wingspan). Both species are harmless to humans.
They are filter feeders, gathering zooplankton* through their open mouths when they swim.
Gestation — pregnancy — lasts for one year and they give birth to live pups.
They are usually all black or all white, or black and white. Most common is a black back and white belly, thought to make it difficult for predators to see from above (looking down into the water) and difficult to see from below (looking up into the Sun).
Project Manta is a long-running research project based at the University of Queensland that aims to further our understanding of manta rays.
The project’s scientists welcome photos of manta rays from citizen scientists. Each manta ray has unique patterns on its underside and photos help the scientists learn about movement and behaviour.

Poem of the Senses – Manta Ray
A manta ray is a huge, beautiful creature, but a pink one. Well, that’s just amazing. Imagine you are Mr Laine, diving in the ocean and seeing this glorious sight.
Use as many senses (sight, sound, touch, taste, smell) as you can to write a poem describing the owe and beauty of such a sight.
