Montastraea annularis

Montastraea annularis at Molasses Reef, Florida Keys

Montastraea annularis, commonly known as the boulder star coral, is a species of coral that lives in the western Atlantic Ocean and is the most thoroughly studied and most abundant species of reef-building coral in the Caribbean to date.[1] It also has a comprehensive fossil record within the Caribbean.[2][3] This species complex has long been considered a generalist that exists at depths between 0 and 80 meters[4] that grew into varying colony shapes (heads, columns, plates) in response to differing light conditions.[5] Only recently with the help of molecular techniques has M. annularis been shown to be a complex of at least three separate species.[6][7][8] Those species are divided into M. annularis, M. faveolata, and M. franksi.

A related species is M. cavernosa, which has larger polyps.
