The unassuming rock goby, a small fish that can be found in rock pools around the United Kingdom, southern Europe and North Africa, is a master of camouflage, a new study finds.
Within a minute, the rock goby can change its color and brightness to disguise itself from hungry predators, such as birds and fish.
"These small fish that live in rock pools need excellent camouflage to avoid predators, and because they're often seen against many backgrounds, rapid color change enables them to be hidden in many places quickly," said lead researcher Martin Stevens, a senior research fellow in the Centre for Ecology and Conservation at the University of Exeter, in the United Kingdom.
