Scientists to See Corals with Fish Eyes

07.12.2015

Specialists of the University of Queensland (Australia) studied 12 species of fish inhabiting coral reefs, including wrasse and parrot fish to find out how they perceive different colors. The main object of study was opsins, light-sensitive receptors in the cells of the retina.

The findings will help to determine which fish are able to see ultraviolet spectrum and which can see the red one, and to find out the true purpose of brightly colored fish - whether it is a means of masking, or on the contrary, a means to claim their rights to the territory. With this knowledge, scientists can predict what will happen to the fish in the future due to climate change. It is known that increasing ocean temperature leads to gradual coral bleaching, and possibly some species will be more vulnerable to predators, becoming more visible.
