Brain coral (Colpophyllia natans) is a hard coral that is easily recognized by its brainy shape. Rock-like hard corals are often mistaken for rocks and touched by divers or snorkelers to stabilize. By touching coral to stabilize yourself or to take a photo you could kill hundreds of polyps. (Read more here).

Soft corals often have the most stunning shapes and bright colors. This is a tree coral, or Nephtheidae, or Dendronephthya hemprichi. Picture taken at Raja Ampat, Indonesia. True soft corals are easily recognized by their eight arms. They do not produce a calcium skeleton.

Sea fans or Gorgonians (Gorgonia flabellum) belong to the Octocorals, often referred to as soft corals. Gorgonians often have a branching fan-like form. They face water currents to expose catch food, they are filter-feeders.

This massive Elkhorn coral (Acropora palmata) has beautiful branches! colonies are fast growing, making it a master reef builder. They belong to the hard corals and can grow up to 3 meters / 10 feet high.
