Background The drastic decline in the abundance of Caribbean acroporid corals (Acropora cervicornis, A. palmata) has prompted the listing of this genus as threatened as well as the development of a regional propagation and restoration program. The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. Surprisingly some Acropora species have actually been seen capturing live fish (Sisson 1973). Corals, specifically the Atlantic staghorn coral, Acropora cervicornis, are under major threat as disturbance events such as storms and disease and predation outbreaks increase in frequency.

Of these species, only Acropora cervicornis, Acropora palmata, and the hybrid Acropora prolifera are found in the Caribbean and Western Atlantic. Sedimentation of its aquatic habitat threatens the staghorn coral, as the increased sediment prevents light from reaching the lower portion of the coral … Climate change is increasing the risk of extinction. Staghorn coral can form dense groups called thickets in very shallow water.

Elkhorn (Acropora palmata) and staghorn (A. cervicornis) corals were listed as threatened under the U.S. Coral reefs are the most diverse ecosystems in the marine world and can take 10,000 years to form. Genetic research has demonstrated that gene flow is regionally restricted across the Caribbean in both species. Acropora White Syndromes. Rising sea temperature increases algae growth so oxygen levels become too high for the coral, causing "bleaching"—the coral expels the algae and dies. Staghorn coral Acropora cervicornis. and Staghorn (Acropora cervicornis) coral reef zones have almost disappeared from most islands in.
