Elkhorn Corals

Elkhorn coral (Acropora palmata) is a large, branching coral with thick and sturdy branches resembling elk antlers. Colonies are fast-growing with branches increasing in length by 2-4 inches/5-10 cm per year and colonies reaching their maximum size in approximately 10-12 years. Elkhorn coral was formerly the dominant species in shallow water (3 ft-16 ft/1-5 m deep) throughout the Caribbean and on the Florida Reef Tract, with large stands forming extensive, densely aggregated fields in areas of heavy surf.

Shelter and Structure

Staghorn, elkhorn, and star corals have been paramount in reef growth throughout the Caribbean and Tropical Western Atlantic for the past 5,000 years. They provide shelter and structure for many species of reef inhabitants and are visually stunning representatives of coral reef systems. Part of what makes the reefs so beautiful and effective habitats is how corals grow in various shapes. With the dense “ears” of the elkhorn creating a canopy, the intertwining branches of the staghorn forming a thicket, and the expansive star corals giving other organisms a solid base to grow on, there is plenty of nooks for fish and invertebrates to find a protective home.
