US Scientists from the University of Iowa and Northwestern University have used a tiny tropical fish to find out more about the development of serious skin cancer.
The molecular set up of embryonic Zebrafish is believed to prevent tumours from developing and experts hope that studying the fish will help them to better understand the cause of melanomas.
Researchers implanted zebrafish embryos with human skin cancer cells and found that they moved around and divided as normal but did not form tumours.
Dr Robert Cornell, who worked on the study, said: "These cancer cells don't do what they do in other circumstances, such as when they are placed under a mouse's skin.
"The objective of our work is to use this very simple system to identify the exact component that can influence the behaviour of melanoma and other cancer types."
He added that further studies of zebrafish could produce new cancer treatments.
"When we identify the crucial factor, whatever it may be, we can look for the equivalent in humans, or make a synthetic version," he said.
