# Montipora

Montipora is a genus of Scleractinian corals in the phylum Cnidaria. Members of the genus Montipora may exhibit many different growth morphologies. With eighty five known species, Montipora is the second most species rich coral genus after Acropora.

## Description

Growth morphologies for the genus Montipora include submassive, laminar, foliaceous, encrusting, and branching. It is not uncommon for a single Montipora colony to display more than one growth morphology. Healthy Montipora corals can be a variety of colors, including orange, brown, pink, green, blue, purple, yellow, grey, or tan. Although they are typically uniform in color, some species, such as Montipora spumosa or Montipora verrucosa, may display a mottled appearance.
Montipora corals have the smallest corallites of any coral family. Columellae are not present. Coenosteum and corallite walls are porous, which can result in elaborate structures. The coenosteum of each Montipora species is different, making it useful for identification. Polyps are typically only extended at night.
Montipora corals are commonly mistaken for members of the genus Porites based on their visual similarities, however, Porites can be distinguished from Montipora by examining the structure of the corallites.

## Distribution

Montipora corals are common on reefs and lagoons of the Red Sea, the western Indian Ocean and the southern Pacific Ocean, but are entirely absent in the Atlantic Ocean.

## Ecology

Montipora corals are hermaphroditic broadcast spawners. Spawning typically happens in spring. The eggs of Montipora corals already contain zooxanthellae, so none is obtained from the environment. This process is known as direct or vertical transmission.
Montipora corals are preyed upon by corallivorous fish, such as butterflyfish. Montipora corals are known to host endo- and ectoparasites such as Allopodion mirum and Xarifia extensa. A currently undescribed species of nudibranch in the genus Phestilla has also been reported in the scientific and aquarium hobbyist literature to feed on the genus.
Montipora corals are susceptible to the same stresses as other Scleractinian corals, such as anthropogenic pollution, sediment, algal growth, and other competitive organisms.

## Evolutionary history

A 2007 study found that the genus Montipora formed a strongly supported clade with Anacropora, making it the genus with the closest genetic relationship to Montipora. It is thought that Anacropora evolved from Montipora relatively recently.
