Small Fish Develop Disguises for Survival

A recent study, performed by researchers from Australia’s ARC Center of Excellence for Coral Reef Studies (CoECRS) and James Cook University, reveals that particular tiny fish have developed deceiving behaviors and features to enhance their survival chances against predatory fish. The damsel fish, a tiny yellow fish with an eyespot on its tail, is capable of changing the size of its actual eye and eyespot in order to confuse and distract larger predators. This is the first study to document predator-induced changes in the size of eyes and eyespots in prey fish.
