1. Siderastrea glynni

About

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.

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.
