Corals SI


Corals are marine invertebrates who typically live in compact colonies of many identical individual polyps. A coral "group" is a colony of myriad genetically identical polyps. Some corals can catch small fish and plankton, using stinging cells, but most corals obtain the majority of their energy and nutrients from photosynthetic unicellular dinoflagellates that live within their tissues.
