Tiny amphibious fish may give an insight into how life survived the transition from aquatic to terrestrial habitats.
According to NSW scientists, the Pacific leaping Blenny, which grows to only eight centimetres and spends its time leaping from rock to rock, defending territory and feeding on the tropical island of Guam, provides an evolutionary snapshot of each stage of the land invasion by fish, News.com.au reported.
Dr. Terry Ord and Courtney Morgans discovered that the fish are uniquely camouflaged to their rocky environments and this helps them avoid being eaten by land predators.
