The following species are currently recognized: [2]. Platygyra acuta Veron, 2002; Platygyra carnosus Veron, 2002; Platygyra contorta Veron, 1990; Platygyra crosslandi (Matthai, 1928) ...
The skeleton of a stony coral in the order Scleractinia is secreted by the epidermis of the lower part of the polyp; this forms a corallite, a cup-shaped hollow made of calcium carbonate, in which the polyp sits. In colonial corals, following growth of the polyp by budding, new corallites are formed, with the surface of the skeleton being ...
Pavona clavus is typically found on coral reefs at depths of 2–40 m (6 ft 7 in – 131 ft 3 in), often on slopes and in areas exposed to currents. [1] It prefers protected or semi-protected habitats and is absent from very shallow, high energy reef platforms.
Scolymia, commonly called scoly coral, is a genus of large-polyp stony corals (Scleractinia). These animals are believed date back to the Miocene with three extant species present in the eastern Atlantic Ocean. [1] [2]
Tubastraea coccinea was first documented in 1943 on Caribbean reefs in Curaçao and Puerto Rico. [3] T. coccinea is an invasive species that was documented to have spread as far north as the Florida Keys National Marine Sanctuary in 2004.
Oxypora glabra is a species of scleractinia coral, otherwise known as stony or hard coral, and part of the family Lobophylliidae, which is characteristic of robust coral colonies.
