(CNN) - It turns out, humans aren't the only ones getting skin cancer.
Scientists discovered the cancer in wild fish in Australia's Great Barrier Reef region.
The findings, published online by the journal PLoS One, showed about 15 percent of the coral trout had a form of melanoma.
Researchers noticed the dark spots on the normally bright colored fish.
While they initially thought the patches were caused by an infection, it was later determined to be cancer.
Scientists believe ultraviolet radiation is to blame for the cancerous legions.
Australia and the Great Barrier Reef region sits directly under the largest hole in Earth's ozone layer.
