A professional fisherman in the Netherlands was left stunned after he caught an extraordinary bright-yellow catfish.
Martin Glatz, who was fishing with his twin brother Oliver on a lake, had caught many catfish, but he had never seen anything like this before – a wels catfish.
Wels catfish are reportedly native to lakes and rivers throughout Europe, and can grow to 2.7 metres long if they live to become fully grown.
But this example of the incredible fish may have had a rare genetic disorder known as leucism, a rare genetic disorder that causes a reduction of pigmentation in skin and hair.
“I have never seen such a catfish before. I am still overwhelmed by it,” Glatz told Live Science.
Despite looking very striking to humans, animals with leucism often live at a disadvantage as their bright pigment can make them easier to spot, making it more difficult to avoid predators or to sneak up on prey.
