An octopus with a see-through head has been captured on camera by a curious photographer.
Wu Yung-sen, 42, was exploring in the sea of Anilo, Philippines, when he stumbled across the unusual-looking mollusc.
In his amazing images, the rare larval – or baby – octopus appears to have a see-through head, allowing observers to see its entire, neon-red brain.
Wu said: “This is an octopus larval, or a wunderpus larv, and I discovered it during a night dive.
“I knew it was very rare, so I had to take the photograph very quickly.”
Company consultant Wu, who has been an underwater photographer for four years and is originally from Taiwan, loves to photograph marine animals.
He added: “I was inspired to start taking underwater photographs because it is difficult to describe the beauty of the ocean with words, so I chose pictures.”
