Porites is a genus of stony coral; they are SPS (Small Polyp Stony) corals. They are characterised by a finger-like morphology. Members of this genus have widely spaced calices, a well-developed wall reticulum and are bilaterally symmetrical. Porites, particularly Porites lutea, often form microatolls.Corals of the genus Porites also often serve as hosts for christmas tree worms (Spirobranchus giganteus).
Specimens of Porites are sometimes available for purchase in the aquarium trade. Most Porites that are collected have Christmas tree worms (Spirobranchus giganteus) that bore into the coral, serving as additional aesthetic livestock. These particular Porites specimens are called "christmas tree worm rocks" or "christmas tree worm coral". However, due to the strict water quality, lighting and dietary requirements, keeping Porites in captivity is very difficult.
