Fish have skin cancer for the first time

Local fishermen call them Rambo fish because their skin is full of scars and has an unusually dark color, looking like they just returned from the war. In fact, these are the first natural fish to have skin cancer.

A salmon has cancer

The sick salmon live in Australia's large coral reefs, attracting the attention of researcher Michael Sweet at Newcastle University (UK) since last year. Sweet and his colleagues eliminated the possibility that they had skin fungi, because black scars that looked like melanoma on human skin were a sign of skin cancer.

These fish live in fresh water, so the cause of their disease may be due to the ozone hole, which causes radiation to rise to the area. This reason may explain why there are up to 15% of the fish that scientists have obtained on the skin.

A number of other wild animals have also been found to be cancerous like Tasmanian carnivores and white whales.
