Agaricia tenuifolia, commonly known as thin leaf lettuce coral, is a species of colonial stony coral in the family Agariciidae. This coral is found in shallow waters in the Caribbean Sea and Gulf of Mexico.
In sheltered waters, A. tenuifolia forms irregular encrusting patches with many vertical, leaf-like blades. The corallites, which are on both sides of these blades, are arranged in meandering rows separated by irregular ridges. [3] In places with more vigorous wave action, this coral may form spherical colonies. The colour of this coral is usually pale brown, reddish-brown or greenish-brown. [4]
A. tenuifolia is native to the Caribbean Sea and the Gulf of Mexico. It is common in the southern part of this range but less so in the north. It occurs on shallow-water reefs and lagoons at depths between 1 and 15 metres (3 and 49 ft). [1]
A. tenuifolia is a zooxanthellate species of coral, having symbiotic unicellular dinoflagellates housed in its tissues. These are photosynthetic and use the sun's energy to create nutrients which the coral is able to use and on which it relies for much of its nutritional needs. The coral also feeds at night when the polyps expand and extend their tentacles to catch the zooplankton floating past. [4]
A. tenuifolia is susceptible to bleaching, a process where the coral expels the zooxanthellae from its tissues and turns white. This happens under adverse circumstances, such as when the water temperature becomes too high. [5] This coral recruits readily to open patches of reef in the Meso-American barrier reef off Belize, but could be considered a "coral weed" as it prevents other, more long-lived corals from recruiting. [6] In this location, corals were affected by a severe bleaching event in 1999 and although other species later recovered, A. tenuifolia suffered 100% mortality. [5]
A. tenuifolia is susceptible to bleaching and coral diseases, which put it at risk, but it is a fast-growing species and readily colonises disturbed areas of the reef and therefore has the potential to recover rapidly. For these reasons, the International Union for Conservation of Nature has assessed its conservation status as being Critically endangered. [1]
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.
Agaricia is a genus of colonial stony corals in the family Agariciidae. These corals are found in shallow waters of the West Indies.
Pavona cactus, the cactus coral, potato chip coral or leaf coral, is a species of colonial stony coral in the family Agariciidae. This coral is found in shallow waters on reefs and in lagoons in tropical parts of the Indo-Pacific region.
Lobophora variegata is a species of small thalloid brown alga which grows intertidally or in shallow water in tropical and warm temperate seas. It has three basic forms, being sometimes ruffled, sometimes reclining and sometimes encrusting, and each form is typically found in a different habitat. This seaweed occurs worldwide. It is the type species of the genus Lobophora, the type locality being the Antilles in the West Indies.
Acropora nasuta is a species of branching stony coral in the family Acroporidae. It is native to the western and central Indo-Pacific where it is found in shallow reef habitats. Like other corals of the genus Acropora, it is susceptible to coral bleaching and coral diseases and the IUCN has listed it as being "Near Threatened".
Micromussa regularis is a species of coral found in Indo-Pacific waters from Australia to the western Pacific Ocean. It is usually uncommon throughout its range, but can be more common locally. It has a narrow depth range, and so is susceptible to coral bleaching and disease. It is also threatened by the global decline in coral reef habitats.
Alveopora fenestrata is a species of stony coral that is found in the Red Sea, the Gulf of Aden, the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia and the oceanic west Pacific Ocean. It can be found in shallow coral reefs, to a depth of 30 metres (100 ft). It is particularly susceptible to coral bleaching.
Alveopora spongiosa is a species of stony coral that is found in the Red Sea, the Gulf of Aden, the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia Japan, the East China Sea and the oceanic west and central Pacific Ocean. It can be found on protected upper coral reef slopes, generally from depth of 9–20 m, but can grow at depths of up to 50 m. It is moderately susceptible to coral bleaching, and is harvested for the aquarium trade.
Alveopora verrilliana is a species of stony coral that is found in the Red Sea, the Gulf of Aden, the northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan, the East China Sea, the oceanic west and central Pacific Ocean and the Johnston Atoll. It can also be found in Palau and the southern Mariana Islands. It grows on shallow coral reefs to a depth of 30 metres (100 ft). It is particularly susceptible to coral bleaching and is harvested for the aquarium trade.
Orbicella faveolata, commonly known as mountainous star coral, is a colonial stony coral in the family Merulinidae. Orbicella faveolata is native to the coral coast of the Caribbean Sea and the Gulf of Mexico and is listed as "endangered" by the International Union for Conservation of Nature. O. faveolata was formerly known as Montastraea faveolata.
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.
Turbinaria is a genus of colonial stony corals in the family Dendrophylliidae. Common names for this genus include disc coral, scroll coral, cup coral, vase coral, pagoda coral and ruffled ridge coral. These corals are native to the Red Sea, Indian Ocean, Japan and the south Central Pacific Ocean.
Turbinaria bifrons, commonly known as disc coral, is a species of colonial stony coral in the family Dendrophylliidae. It is native to the Indo-Pacific region. It is a zooxanthellate coral that houses symbiont dinoflagellates in its tissues. This is an uncommon species and the International Union for Conservation of Nature has rated its conservation status as being "vulnerable".
Turbinaria frondens, commonly known as disc coral, is a species of colonial stony coral in the family Dendrophylliidae. It is native to the Indo-Pacific region. It is a zooxanthellate coral that houses symbiont dinoflagellates in its tissues.

It is an uncommon species and the International Union for Conservation of Nature (IUCN) has rated it as a "vulnerable" species.
Agaricia agaricites, commonly known as lettuce coral or tan lettuce-leaf coral, is a species of colonial stony corals in the family Agariciidae. This coral is found in shallow waters in the tropical western Atlantic Ocean and the Caribbean Sea. The IUCN has assessed its status as being Vulnerable.

Lighthouse Reef is an atoll in the Caribbean Sea, the easternmost part of the Belize Barrier Reef and one of its three atolls, the other two being Turneffe Atoll and Glover's Reef. Lighthouse Reef is located about 80 kilometres (50 mi) southeast of Belize City. The atoll is of oblong shape, approximately 35 kilometres (22 mi) long from north to south, and about 8 kilometres (5.0 mi) wide. It forms a shallow sandy lagoon with an area of 120 square kilometres (46 sq mi) and a depth between 2 to 6 metres deep.
