Description

Montipora coral, Arthur Bay, Magnetic Island, January 2016

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

. ''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.
