Scientists may have found an explanation for why the first amphibious fish moved from water to land. On a small island in the South Pacific Ocean, four species of blennies spend half their time in water and half on land. To test whether predation could be driving the transition to land, researchers created blenny mimics and dispersed them throughout the blennies’ habitats. They found that the aquatic mimics were attacked at a much higher frequency than the terrestrial mimics were, making predation a viable cause for the water-to-land transition.
