Researchers in Australia and Sweden have discovered that coral bleaching and death has a direct effect on how the live reef fish learn may have about their environment - mainly as predators to avoid.
The team of James Cook University in Queensland and Uppsala University conducted tests in enclosed spaces "Mini Reef" simulates the environment they were studying.
They put the girls on their reefs, half of them healthy coral contained, contains the other half, the skeletons of dead coral.
Then trained scientists the fish to detect the smell of a new predator - this perfume pairing with another chemical release Castañuela when attacked. Only fish healthy reefs learned the smell of new predators and hid in reaction among the coral. In the dead reefs the fish was still to be investigated, to rely vulnerable.
The researchers say that their results show worrying signs of the direct impact of coral damage in the behavior and survival of marine animals.
The results are published in the Proceedings of the Royal Society B journal .
