Fish That Dance On Molten Sulpher Ponds

Researchers from the University of Victoria, Canada, have come across tonguefish that like to skip across pools of molten sulphur of undersea volcanoes in the western Pacific. The measured temperature is more than 180C (355F). The fish live on the edge of the pools, and in a couple of cases the scientists saw them out on the surface of a pool. The fish have been studied with remotely operated submersibles. The phenomenon has amazed the scientists and they are trying to work out how the creatures survive in such a hostile environment.
