Many coral reefs are dying out and many are in danger of doing so. Climate change is the main factor. As the climate changes, hurricanes become a more frequent appearance. These hurricanes cause severe damage to coral reefs. Climate change and over fishing makes it difficult for coral reefs to heal and rebuild themselves. Fish that live in coral reefs are also harmed. As the temperature gets warmer, the cycle that brings nutrients to the surface water is a much more difficult process. These fish that live in and near coral reefs die from lack of nutrients. One adaption that might help rebuild the population of the fish that inhabit coral reefs is the ability to go longer without food. Deep sea creatures have adapted to be able to go long periods of time without food. If the fish that reside in coral reefs were able to do this, they would be able to survive longer and reproduce, thus increasing the population. The coral reefs themselves rely on the fish that live there for its own survival.
