Acropora

Acropora represents a captivating genus of small polyp stony corals within the phylum Cnidaria. This group encompasses renowned species such as table coral, elkhorn coral, and staghorn coral, with over 149 species identified. These corals are essential to reef ecosystems because they construct the calcium carbonate skeletons that form the foundation of the reefs.

Acropora corals are colonial, meaning they consist of numerous individual polyps. These polyps can retract for protection and extend to feed on plankton and organic matter. Unfortunately, these corals face various environmental threats, leading to population declines and heightened vulnerability to bleaching events. Bleaching occurs when corals expel their symbiotic algae, resulting in a white appearance and potential mortality. Factors such as pollution, elevated water temperatures, ocean acidification, sedimentation, and eutrophication contribute to bleaching. Consequently, some Acropora species are currently listed as Threatened.

In the realm of reef-keeping, Acropora corals are highly prized for their vibrant colors. Many aquarists cultivate these corals in captivity, but they require precise conditions to thrive, including bright light, stable temperatures, and high water quality. Reef aquariums also contend with challenges like parasites, including Acropora-eating flatworms and red bugs.
