Corals lack an internal skeleton and are often sedentary. They feed on fish or plankton and rely on photosynthetic algae for nutrients. Environmental stress can lead to coral bleaching. Corals reproduce both sexually and asexually, forming large colonies and reefs that support diverse marine ecosystems.
