They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. Staghorn Coral GALLERY Acropora cervicornis. The losses were caused by a combination of coral disease and bleaching, with possible contributions from other stressors, including pollution and predation. We compared linear extension, calcification rate, and skeletal density of nursery-raised A. cervicornis branches reared for 6 months either on blocks attached to … In 2006, these two important reef-building species were listed as threatened under the Endangered Species Act due to significant declines in their populations throughout the wider Caribbean, including the Florida Keys. Elkhorn and staghorn corals were once the most abundant and important species on Atlantic/Caribbean coral reefs in terms of building reef structure. It’s commonly called staghorn coral because the pointed branches rise from the reef like antlers. 1–25 m, Aronson et al., 2008) and reef types (i.e. Small patches can be found in shallow reef environments and occasionally in open areas of sand bottom. Other threats from climate change are sea level rise, changes in currents and storm damage. The Staghorn Coral, Acropora Cervicornis is one of those 3. Its branches are spaced more loosely with a more relaxed look to them.
