The health of ocean habitats is a delicate balance of the presence of the right species and the proper conditions. When things are out of balance the health of habitats can be at stake. Coral reef habitats act as a host for a diverse amount of species of invertebrates and vertebrates; however, the reefs are sensitive to physical and chemical changes which we often discuss on this podcast, but we rarely discuss the biological changes that can occur including the presence of predators and prey.
