Description

Members in this genus are usually thin corals that form leafy, plate-like, encrusting or semi-massive colonies. The colours vary greatly. The calices are less than 2 mm in diameter and are usually well separated by the coenosteum. The skeleton is lacy, the walls are indistinct and the septa, when present are small and in 2 cycles. The columella is rarely developed and the corallites are inconspicuous and appear empty as the polyps are very small.

Biology

Like other corals, Montipora corals are colonies of individuals, known as polyps, which are about 2 mm across and share tissue and a nerve net. The polyps can withdraw into the coral in response to movement or disturbance by possible predators, but slightly protrude when undisturbed. The polyps usually extend further at night to capture zooplankton from the water. These corals have zooxanthella
Zooxanthella
Zooxanthellae are flagellate protozoa that are golden-brown intracellular endosymbionts of various marine animals and protozoa, especially anthozoans such as the scleractinian corals and the tropical sea anemone, Aiptasia....

Photosynthesis is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can...

In aquaria

Most Montipora corals are brown, pink, or green but variants with bright colors or having a ridge color with a high contrast to the core color, such as the rainbow and superman Montipora are more prized by aquarists. Captive propagation of Montipora corals is widespread in the reefkeeping community. Able to endure varied conditions, Montipora corals can be grown by enthusiasts without the use of metal halide lighting
Metal halide lamp
Metal-halide lamps, a member of the high-intensity discharge family of lamps, produce high light output for their size, making them a compact, powerful, and efficient light source. By adding rare earth metal salts to the mercury vapor lamp, improved luminous efficacy and light color is obtained...
