Orbicella franksi, commonly known as Boulder star coral, is a colonial stony coral in the family Merulinidae. It is native to shallow waters in the Caribbean Sea, the Gulf of Mexico, the Bahamas, Bermuda and Florida, and is listed as a "vulnerable species" by the International Union for Conservation of Nature.

Taxonomy

Until recently this coral, along with Orbicella faveolata , was thought to be a variety of Orbicella annularis . There is very little morphological differences between them but studies have shown differences in corallite structure, life history, allozymes and distribution. All three members of this species complex used to be placed in the genus Montastraea . [3]

Description

Colonies of Orbicella franksi usually form massive clumps with uneven surfaces, but sometimes forms plates, and in shady positions, may be encrusting. The general colour is orange-brown, greenish-brown or greyish-brown, but the extremities of the lumps are often pale or white. The corallites (the cups in which the polyps sit) are small, measuring 3.5 mm (0.14 in) across. The growing edges of this coral bear both large and small corallites which is in contrast to the closely related Orbicella faveolata , which has regularly spaced corallites at its growing edges. [4]

Distribution and habitat

Orbicella franksi is native to the Caribbean Sea and the Gulf of Mexico, including Florida, the Bahamas and Bermuda. It typically grows on fore reefs (where it may be the most common species of coral) and its depth range is 5 to 50 metres (16 to 164 ft) but it is typically found at depths of between 15 and 30 metres (49 and 98 ft). [1]

Status

Orbicella franksi seems to be more resistant to coral diseases than some members of its genus, but is still susceptible to coral plague, yellow-band disease, black band disease and coral bleaching. [1] The major threats it faces include climate change, ocean acidification and destruction of its reef habitat. The International Union for Conservation of Nature has rated its conservation status as being near threatened. [1]

Pillar coral is a hard coral found in the western Atlantic Ocean and the Caribbean Sea. It is the only species in the monotypic genus Dendrogyra. It is a digitate coral -that is, it resembles fingers or a cluster of cigars, growing up from the sea floor without any secondary branching. It is large and can grow on both flat and sloping surfaces at depths down to 20 m (65 ft). It is one of the few types of hard coral in which the polyps can commonly be seen feeding during the day.

<i>Orbicella annularis</i> Species of coral

Orbicella annularis, commonly known as the Boulder star coral, is a species of coral that lives in the western Atlantic Ocean and is the most thoroughly studied and most abundant species of reef-building coral in the Caribbean to date. It also has a comprehensive fossil record within the Caribbean. This species complex has long been considered a generalist that exists at depths between 0 and 80 meters that grew into varying colony shapes in response to differing light conditions. Only recently with the help of molecular techniques has O. annularis been shown to be a complex of at least three separate species. Those species are divided into O. annularis, O. faveolata, and O. franksi. This coral was originally described as Montastraea annularis.

Yellow-band disease is a coral disease that attacks colonies of coral at a time when coral is already under stress from pollution, overfishing, and climate change. It is characterized by large blotches or patches of bleached, yellowed tissue on Caribbean scleractinian corals.

Eusmilia is a genus of stony coral in the family Meandrinidae. It is a monotypic genus represented by the species Eusmilia fastigiata, commonly known as the smooth flower coral. It is found on reefs in the Caribbean Sea.

<i>Pseudodiploria strigosa</i> Species of coral

<i>Colpophyllia</i> Genus of corals

Colpophyllia is a genus of stony corals in the family Mussidae. It is monotypic with a single species, Colpophyllia natans, commonly known as boulder brain coral or large-grooved brain coral. It inhabits the slopes and tops of reefs, to a maximum depth of fifty metres. 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 ridges are usually brown with a single groove, and the valleys may be tan, green, or white and are uniform in width, typically 2 centimetres. The polyps only extend their tentacles at night.
