Relate recharge features to aquifers.Bleaching does not just affect corals. The impacts affect many reef animals because corals form the complex habitats that marine animals need. Fish, for example, typically decrease in numbers after a bleaching event. Even species that do not feed directly on corals suffer, because they need diverse complex reef structure for places to hide.
