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.
Scolymia lacera is a coral with a single, solitary polyp and does not increase in size by budding as do colonial species of coral. It is a small species with a diameter of up to 6 centimetres (2.4 in). The radially-running ridges in the stony cup which it secretes can be seen through the fleshy body of the polyp. Its colour is variable and is usually some shade of greenish-brown. [3] Scolymia lacera is very similar in appearance to Scolimia cubensis which occupies much the same range. The differences are mostly in the layout of the septa, the miniature ridges in the calcareous calyces in which the polyps sit. S. lacera tends to occupy better lit positions while S. cubensis is in less well lit locations. Where the two come in contact, S. lacera is more aggressive. [4]
Scolymia lacera is found in the Caribbean Sea, the southern half of the Gulf of Mexico, the Bahamas and southern Florida. [1] It grows on reefs, rocky outcrops and steep reef slopes at depths of between 15 and 80 metres (49 and 262 ft). [3]
Scolymia lacera contains single-celled symbiotic algae called zooxanthellae in its tissues. These are photosynthetic and use energy from the sun to produce organic compounds from which the coral also benefits. Much of its energy needs are supplied in this way but it also extends its ring of short tentacles to catch plankton, feeding mostly at night. Scolymia lacera is an aggressive coral that attacks neighbouring corals that might deprive it of light. It does this by extruding filaments several centimetres long from its mesenteries. [3] When these come in contact with another coral they secrete enzymes that in the course of several hours digest its soft tissues. Smaller corals may be killed by this attack while larger individuals may have the part within reach stripped back to the skeleton. [5]
The IUCN Red List of Threatened Species lists this species as being critically endangered. Some of the factors affecting corals are a rise in sea temperature and consequent coral bleaching, increased severity of storms, ocean acidification, coral disease and various human impacts. [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.
Scolymia, commonly called scoly coral, is a genus of large-polyp stony corals (Scleractinia). These animals are believed date back to the Miocene with three extant species present in the eastern Atlantic Ocean.
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.
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.
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 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.
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.
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 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.
Micromussa lordhowensis, previously known as the 'Acan Lord', is a species of stony coral in the family Lobophylliidae. It is a widespread and common coral with large polyps occurring on shallow reefs in the Indo-Pacific Ocean. It was originally classified under the genus Acanthastrea, and reclassified under the genus Micromussa in 2016.
Cynarina lacrymalis is a species of stony coral in the family Lobophylliidae. It is variously known as the flat cup coral, solitary cup coral, button coral, doughnut coral, or cat's eye coral. It is found in the western Indo-Pacific Ocean and is sometimes kept in reef aquaria.
Astrangia solitaria, the dwarf cup coral or southern cup coral, is a species of stony coral in the family Rhizangiidae. It is native to shallow water in the western Atlantic Ocean and the Caribbean Sea.
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.
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.
