It, along with elkhorn coral and star corals (boulder, lobed, and mountainous) built Caribbean coral reefs over the last 5,000 years. These wide branches can grow to lengths reaching over 2 meters (~6 feet) and construct vital vertical reef habitat. These trophic levels include: primary producers, primary consumers, … The grooved brain coral is named for its appearance. However, this does not always work out; the Caribbean version of the violet coral snail, the abbreviated coral snail (Coralliophila abbreviata), creates larger and larger denuded areas as it feeds on elkhorn corals, leading to significant tissue loss. Furthermore, there are complex chemicals found in coral reefs that hold promises to modern medicine. This particular food web starts with Phytoplankton, a photosynthetic primary producer that receives its energy from the sun and does not need to consume any organism. Compare this to star corals that may grow about 1 cm a year and you can understand this dramatic difference. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth.

Elkhorn is an intricate, relatively thin branching coral with an army green background and white growth tips and highlights on the coral body. The best bet is the some healthy tissue still remains deep in the skeleton and, if conditions improve, this coral can grow and recover, spreading to the rest of the skeleton.
