Colpophyllia is a genus of stony corals in the family Mussidae. It is monotypic with a single species, Colpophyllia natanscommonly known as boulder brain coral or large-grooved brain coral. It is characterised by large, domed colonies, which may be up to two metres across, and by the meandering network of ridges and valleys on its surface. The polyps only extend their tentacles at night.

Individual colonies of Colpophyllia natans are large and usually broadly domed, with curvature typically increasing with the size, and therefore age, of the colony. They grow up to two metres in diameter and morphologically earn the epithet “boulder”. Colony shape may occasionally be flat-topped discs, particularly when younger. As a type of brain coralthe surface of the skeleton is a network of winding, curving valleys and ridges or walls that roughly resemble the familiar folding architecture of the mammal cerebrum.

The colour of the ridges and valleys vary among colonies, with the ridges being various shades of brown, and the valleys either whitish, green, or tan. The ridge tops are indented with a single thin groove.

Ridges and valleys may be up to 2 centimetres wide, and this breadth distinguishes it from the narrower Diploriawhich may natand be similar in appearance. The robust shape, size, and slow growth of the boulder brain coral allows it more easily to survive conditions to which smaller and more fragile corals, such as the plate-like lettuce coral Agaricia agaricitessuccumb.


Corals in the Caribbean are susceptible to bleaching caused by high water temperatures and solar radiation. A nine-month study conducted in compared the mortality batans C. It is identifiable in fossil records at least since the early Pliocene.

It can be found down to a depth of fifty metres, but is more often established closer to the surface. Colpophyllia natans is a hermaphroditic broadcast spawner, releasing large numbers of gametes synchronously to aid fertilisation.

Each individual polyp spawns both eggs and sperm, having the reproductive capabilities of both the male and female sexes. Following fertilisation, the zygote becomes a microscopic larva called a planulacolppphyllia, upon swimming to suitable substrate, will anchor and establish a new colony.

This method of sexual reproduction has a high rate of failure in several of its stages and few new colonies successfully grow. A total of seven diseases are known to afflict C. It is one of the Caribbean corals most afflicted by black band diseaseand along with Montastraea spp.

Other hosted diseases include white plague types I and II, dark spotand skeletal anomalies, such as tumours and galls. Another pathogen, so far unidentified, killed in one year, between andapproximately half of the corals present in Bird Key Reef of the Dry Tortugas.

Despite this susceptibility to disease, the boulder brain coral is long-lived, with specimens capable of living for more than two hundred years. The first description of Colpophyllia natans as a species was published by the Dutch physician and naturalist Maarten Houttuyn.
