Tropical fish are invading Australian ocean water

A University of Adelaide study found that climate change is helping tropical fish species invade temperate Australian waters. The warming current keeps baby fish warm, increasing their survival chances. As temperatures rise, these tropical fish will eventually grow to their full size and compete with native fish for resources.
