As the colony grows the staghorn branches create a three-dimensional lattice where baby fish can easily hide and avoid larger predators. Collection and removal of herbivorous fishes also result in corals becoming overgrown by macroalgae, preventing resettlement of new corals in damaged reefs. Acropora cervicornis is susceptible to disease and climate change in particular coral bleaching. SUMMARY: NMFS announces the 90-day finding for a petition to list elkhorn coral (Acropora palmata), staghorn coral (A. cervicornis), and fused-staghorn coral (A. prolifera) as endangered or threatened, and to designate critical habitat under the Endangered Species Act (ESA). 0 : parseInt(e.tabh); NEPR Benthic Habitat Map 2015. 1 : (pw-(e.tabw+e.thumbw)) / (e.gw[ix]); In the images of Acropora coral from Cordelia Banks you can see a fortress of staghorn corals with very few fish swimming in the water. Elkhorn coral grows in the heavy surf areas of reef structures usually in 20 feet of water or less and may form dense "thickets" of structures which provide habitat for fish and invertebrates. A heterogeneous habitat such as this, may facilitate coexistence between competitors within the same colony by increasing the number of available microhabitats and territories in a spatial scale ranging from centimeters to a few meters. Pointed branches of Acropora cervicornis rise from the reef like antlers and the common name for this corals is the Staghorn Coral. Während die Blumentiere im flachen Wasser und auf den Riffdächern meist busch- oder geweihförmig wachsen, bilden sie an den Riffabhängen oft tischförmige Stöcke und wachsen, um noch möglichst viel Licht aufzufangen, waagerecht nach außen.

Staghorn corals (Acropora cervicornis) are propagated within underwater coral nurseries to create a sustainable source of corals for use in coral restoration activities (inset). 0 : e.tabh; They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. The structural complexity provided by A. cervicornis and its congener, A. palmata , provides essential habitat for a multitude of reef-associated organisms (Reviewed in Bruckner, 2002 ). The lower depth limit of a staghorn coral is defined due to the amount of light present and the quantity of suspended sediments whereas the upper depth limit is determined from wave action. Acropora cervicornis structures, full of crevices and holes, serve as refuge for different fish species, some of them being in juvenile phases.
