Stephanocoenia intersepta, commonly known as blushing star coral or small eyed star coral, is a species of colonial stony corals in the family Astrocoeniidae. 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 Near Threatened [1]
Stephanocoenia intersepta commonly grows in a flattened hemispherical shape. Occasionally misidentified as massive starlet coral (S. siderea), S. intersepta has large, protruding corallites as opposed to S. siderea's retracted corallites. Polyp tentacles are usually extended during the day, contributing to its cream, tan, gray, or brown color. When disturbed, these tentacles retract, changing the color of the coral and giving it the common name blushing star coral.
This coral is found in reefs occupying the majority of the Caribbean Sea, Gulf of Mexico, and Florida Keys. Typically found between depth of 1m and 100m, it has been found as far south as the coast of Brazil. [2] [3]
This coral is a zooxanthellate species, which contains single-celled dinoflagellates in its tissues. These are photosynthetic and provide the coral with 70% to 95% of its energy needs. The rest of its needs are supplied by the polyps which trap passing plankton.
Found in most reef communities, the crustose form of this coral is typically found in shallower environments between 5 and 15 meters, while the boulder form is found in deeper communities (10-20m). The average age of maturity is around three to eight years, and average generational age is around 10 years. [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.
The organ pipe coral is an alcyonarian octocoral native to the waters of the Indian Ocean and the central and western regions of the Pacific Ocean. It is the only known species of the genus Tubipora. This species is a soft coral but with a unique, hard skeleton of calcium carbonate that contains many organ pipe-like tubes. On each tube is a series of polyps which each have eight feather-like tentacles. These tentacles are usually extended during the day, but will swiftly withdraw with any sort of disturbance. The skeleton is a bright red color, but is typically obscured by numerous polyps. Because of this, living colonies are typically green, blue, or purple due to the color of the expanded polyps. Colonies are typically dome-shaped and can reach up to 3 meters across, while the individual polyps are typically less than 3 mm wide and a few mm long. They are close relatives to other soft coral and sea fans. This species is a popular aquarium coral due to its ease to maintain, as well as higher tolerance compared to most true corals. However, its popularity presents a problem: along with its potential as an aquarium coral, the species' coloration makes it a popular commodity for tourists, leading to a variety of threats to the population.
Duncanopsammia is a monotypic genus of stony corals. It is represented by the single species, Duncanopsammia axifuga, commonly called whisker coral, duncanops coral, or simply duncan coral. Individual polyps are fairly large with round skeletal bases (corallites) 10–14 millimetres (0.39–0.55 in) in diameter and larger central discs from which multiple tentacles radiate; the polyps form a structure branching at irregular intervals to form a large colony.
Porites astreoides, commonly known as mustard hill coral or yellow porites, is a colonial species of stony coral in the family Poritidae.
Homophyllia bowerbanki is a vulnerable species of coral found in the Pacific and Indian Oceans. This species is moderately common, but it is threatened by crown-of-thorns starfish predation and habitat loss.
Galaxea fascicularis is a species of colonial stony coral in the family Euphylliidae, commonly known as Octopus coral, Fluorescence grass coral, and Galaxy coral among various vernacular names.
Plerogyra sinuosa is a jelly-like species of the phylum Cnidaria. It is commonly called "bubble coral" due to its bubbly appearance. The "bubbles" are grape-sized which increase their surface area according to the amount of light available: they are larger during the day, but smaller during the night, when tentacles reach out to capture food. This species requires low light and a gentle water flow. Common names for Plerogyra sinuosa include "grape coral", bladder coral, and pearl coral. According to the IUCN, Plerogyra sinuosa ranges from the Red Sea and Madagascar in the western Indian Ocean to Okinawa and the Line Islands in the Pacific.
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.
Siderastrea siderea, commonly known as massive starlet coral or round starlet coral, is a stony coral in the family Siderastreidae. It is found in shallow parts of the western Atlantic Ocean as solid boulder-shaped or domed structures.
Siderastrea radians, also known as the lesser starlet coral or the shallow-water starlet coral, is a stony coral in the family Siderastreidae. It is found in shallow parts of the western Atlantic Ocean as small, solid mounds or encrusting sheets.
Pseudodiploria strigosa, the symmetrical brain coral, is a colonial species of stony coral in the family Mussidae. It occurs on reefs in shallow water in the West Atlantic Ocean and Caribbean Sea. It grows slowly and lives to a great age.
Pseudodiploria clivosa, the knobby brain coral, is a colonial species of stony coral in the family Mussidae. It occurs in shallow water in the West Atlantic Ocean and Caribbean Sea.
Dichocoenia is a monotypic genus of stony coral in the family Meandrinidae. It is represented by a single species, Dichocoenia stokesii, which is commonly known as pineapple coral, elliptical star coral, or pancake star coral. It is mostly found in the Caribbean Sea and the western Atlantic Ocean. Dichocoenia stokesii has irregular calyces and its form can be either a massive, hemispherical hump or a flat, platform-like structure.
Isophyllia sinuosa, the sinuous cactus coral, is a species of stony coral in the family Mussidae. It is found in shallow water in the tropical western Atlantic and the Caribbean Sea.
Mussa is a genus of stony coral in the family Faviidae. It is monotypic, being represented by the single species Mussa angulosa, commonly known as the spiny or large flower coral. It is found on reefs in shallow waters in the Caribbean Sea, the Bahamas and the Gulf of Mexico.
Lobophyllia corymbosa, also known as lobed cactus coral or brain root coral, is a species of large polyp stony coral in the family Lobophylliidae. It occurs on reefs in shallow waters in the Red Sea, off the coast of East Africa, and in other parts of the tropical Indo-Pacific.
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.
Goniastrea retiformis is a species of stony corals in the family Merulinidae. It is native to shallow water in the Indo-Pacific region.
