Porites porites, commonly known as hump coral or finger coral, is a species of stony coral in the genus Porites . It is found in the Caribbean Sea and western Atlantic Ocean and also along the coast of West Africa.
Porites porites forms irregular patches of short, finger-like lobes with blunt, slightly swollen tips. Sometimes these are densely packed but in other locations they are widely spaced. The lobes are up to 2.5 cm (1 in) wide which distinguishes this species from other members of the genus that have narrower lobes. They may be curved or hooked and grow in all directions. The colour is usually white or pale blueish-grey. [3] [4]
This species is known to be some of the oldest forms of life on earth due to the slow growth rate of the coral. The coral is formed from tiny polyps that attach together at the base of their skeletons and branch outward. Scientists believe that some Porites coral are up to 1,000 years old and can reach heights of eight meters and widths of up to five meters. [5]
Porites porites occurs throughout the Gulf of Mexico, the Caribbean Sea, the Bahamas and southern Florida and as far south as Venezuela. [2] It is also found in shallow tropical seas off the west coast of Africa. [1] It is found from low water mark down to a depth of about 20 metres (66 ft) and occurs on both fore reefs and back reefs where the water is not too turbid. [3] It also occurs on the prop roots of mangroves and among seagrass { Thalassia spp. ). [1]
Porites porites is a zooxanthellate coral, the tissues containing unicellular green algae living symbiotically within the cells. [2] These are photosynthetic and use the carbon dioxide and waste materials produced by the coral, supplying oxygen and organic compounds in return. Unlike most stony corals, the polyps of Porites porites often extend their tentacles to feed in the daytime. [3]
Porites porites is listed as being of "Least Concern" in the IUCN Red List of Threatened Species. This is because it is a common species throughout its range and the population seems stable. It is an adaptable species being found in a wide range of habitats and is not particularly susceptible to bleaching. It is prone to coral diseases but its chief threat is the loss of reef habitat through mechanical damage, violent storms, a rise in sea temperatures, ocean acidification, pollution, increased sedimentation and tourism. [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.
Porites astreoides, commonly known as mustard hill coral or yellow porites, is a colonial species of stony coral in the family Poritidae.
Porites lobata, known by the common name lobe coral, is a species of stony coral in the family Poritidae. It is found growing on coral reefs in tropical parts of the Indian and Pacific Oceans.
Porites compressa, also known as finger coral or hump coral, is a species of marine stony coral in the family Poritidae. It is found growing on coral reefs and in shallow lagoons in tropical parts of the Indian and Pacific Oceans.
Favia fragrum is a species of colonial stony coral in the family Mussidae. It is commonly known as the golfball coral and is found in tropical waters on either side of the Atlantic Ocean.
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.
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.
Scolymia lacera, the fleshy disk coral, is a species of stony coral in the family Mussidae. It occurs on reefs in shallow waters in the Caribbean Sea, the Gulf of Mexico, the Bahamas, Bermuda and southern Florida.
Porites furcata, commonly known as hump coral, thin finger coral or branched finger coral, is a species of stony coral in the genus Porites. It is found in the Caribbean Sea and western Atlantic Ocean.
Meandrina meandrites, commonly known as maze coral, is a species of colonial stony coral in the family Meandrinidae. It is found primarily on outer coral reef slopes in the Caribbean Sea and the Gulf of Mexico.
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 Mussidae. 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.
Favites pentagona is a species of stony coral in the family Merulinidae, sometimes known as larger star coral. It is native to the Indo-Pacific region and its range extends from the Red Sea through the Indian Ocean to the Western Pacific Ocean. This is a common species throughout its wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Favites complanata is a species of stony coral in the family Merulinidae, sometimes known as the larger star coral. It is native to the Indo-Pacific region and its range extends from the Red Sea and Indian Ocean to the western and central Pacific Ocean. This is an uncommon species of coral and seems to be decreasing in abundance, and the International Union for Conservation of Nature has rated its conservation status as being "near threatened".
Heliofungia actiniformis is a solitary species of mushroom coral, a large polyp stony coral in the family Fungiidae. This coral is found in shallow water in the Indo-Pacific region. It is a zooxanthellate species. It is a popular coral in the reef aquarium trade; wild populations are threatened by disease, climate change, and over-collecting, and the species is considered vulnerable by the IUCN.
Manicina areolata, commonly known as rose coral, is a colonial species of stony coral. It occurs in shallow water in the West Atlantic Ocean and Caribbean Sea, sometimes as small solid heads and sometimes as unattached cone-shaped forms.
Porites branneri, known by the common name blue crust coral, is a species of stony coral in the family Poritidae. It is found growing on reefs in the Caribbean Sea and the northern and eastern coasts of South America.
Goniopora tenuidens is a species of colonial stony coral in the family Poritidae. It occurs in shallow water in the tropical Indo-Pacific region. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Dipsastraea pallida is a species of colonial stony coral in the family Merulinidae. It is found in tropical waters of the Indian and Pacific Oceans. This is a common species of coral with a widespread distribution, and the main threat it faces is from the destruction of its coral reef habitats. It is rated as a "least-concern species" by the International Union for Conservation of Nature. This species was first described in 1846 as Favia pallida by the American zoologist James Dwight Dana; it was later transferred to the genus Dipsastraea, but some authorities continue to use the original name.
