It is abundant in Bermuda lagoons and reefs, Florida-Bahamas outer reefs and patch reefs, Jamaica backreefs and reefs, St. Lucia open bay with reef patches, in reefs of Cuba, Barbuda, and Panama, and in reefs of the Belize Shelf where it forms an "Archaias-Asterigerina dominant" assemblage characteristic of high turbulence area.
