    The most affected by dead coral reefs is small fish, and bottom feeders. This is beacuse these fish use the coral reefs as shelter from predators.

    How are the wildlife affected by this?

    The fish don't have shelter and they are eaten by their predators. Without the coral reef as a shelter the small fish and bottom feeders are prone to be killed by the bigger fish/predators.

    What causes death of coral reefs?

    Coral reefs face many threats. Some are natural stresses, such as hurricanes, cyclones, typhoons, earthquakes, or plagues of coral-eating predators like the crown of thorns starfish, about which we can do little. These stresses usually are very episodic or irregular in both space and time, and really healthy reefs will recover from them over time. In a completely different category are the human caused stresses to reefs. These stresses are persistent and constantly intensifying.
