Staghorn Coral contributes to habitat formation, species interactions, and human livelihoods, who rely on reef habitat as a source of protein. It has cyclindrical branches that look like the antlers of a stag, a male deer.
The most generalized threat to corals is global climate change, resulting in temperature extremes and ocean acidification.
Branching corals, like many in the genus Acropora, provide structurally complex habitats for reef fishes and other organisms.Fluctuations in the abundance, distribution and characteristics of thicket-forming staghorn Acroporids may contribute to changes in the abundance and species composition of reef fishes due to changes in the availability of shelter habitat and food. This allows Acropora to outgrow other corals on the reef.
