Ranked the number 1 EDGE Coral, Siderastrea glynni is the only member of its genus found in the Eastern Pacific and is endemic to a tiny area off the Panamanian coast. This species is currently under revision as it is thought to be a junior synonym of Siderastrea siderea
Five colonies were discovered in 1992 but no new recordings have since been put forward. Currently, the remaining colonies reside in captivity at the Smithsonian Tropical Research Institute, also in Panama. It is unknown whether additional wild populations of this species remain undiscovered, however fairly rigorous surveying has so far proved unsuccessful. As a result, this coral is considered Critically Endangered. However, it is thought that these colonies resulted from transferred colonies of Siderastrea siderea in the Caribbean, during the setup of a field experiment early into the 1980s.
