For the first time, scientists have identified widespread skin cancer on an important reef fish species. The Coral Trout (Plectropomus leopardus) was the center of a study conducted by the Newcastle University and the Australian Institute of Marine Science collecting specimens from the southern portion of the Great Barrier Reef Marine Park: Heron Island and One Tree Island.
"The individuals we looked at had extensive -- but only surface -- melanomas," explains Doctor Michael Sweet who led a team that studied 136 sample fish. ?UV radiation appears to be the likely cause," explains Dr. Sweet.? Of the136 specimens, 15% (20 fish) exhibited melanomas lesions on surface of their skin covering from 5% to 98% of their body.
The entire study is available at PLoS ONE.
