Desmophyllum is a genus of cnidarians belonging to the family Caryophylliidae. [1]
The genus has cosmopolitan distribution. [1]
Species: [1]
Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus Vibrio living in symbiosis with the crabs, mostly V. alginolyticus and V. parahaemolyticus.
Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders like other stony corals in the order Scleractinia. Brain corals are found in shallow warm water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or "flower animals". The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height.
Oculina is a genus of colonial stony coral in the family Oculinidae. These corals are mostly found in the Caribbean Sea, the Gulf of Mexico and Bermuda but some species occur in the eastern Pacific Ocean. They occur at depths down to 1000 metres.
The Caryophylliidae are a family of stony corals found from the tropics to temperate seas, and from shallow to very deep water.
Acanthastrea is a genus of large polyp stony corals in the family Lobophylliidae. The colonies are massive and usually flat. The corallites are either circular or angular in shape. The septa are thick near the wall of the corallite, becoming thin near the columella, and have tall teeth. The polyps are extended only at night.
Rhodactis is genus of mushroom corals which are characterized by large individual polyps that are often reminiscent of a mushroom. Rhodactis are related to stony corals but do not produce a stony skeleton.
Holaxonia is a suborder of soft corals, a member of the phylum Cnidaria. Members of this suborder are sometimes known as gorgonians and include the sea blades, the sea fans, the sea rods and the sea whips. These soft corals are colonial, sessile organisms and are generally tree-like in structure. They do not have a hard skeleton composed of calcium carbonate but have a firm but pliable, central axial skeleton composed of a fibrous protein called gorgonin embedded in a tissue matrix, the coenenchyme. In some genera this is permeated with a calcareous substance in the form of fused spicules. Members of this suborder are characterized by having an unspiculated axis and often a soft, chambered central core. The polyps have eight-fold symmetry and in many species, especially in the families Gorgoniidae and Plexauridae, contain symbiotic photosynthetic algae called zooxanthellae. These soft corals are popular in salt water aquaria.
Lobophyllia, commonly called lobed brain coral or lobo coral, is a genus of large polyp stony corals. Members of this genus are sometimes found in reef aquariums.
Isastrea is an extinct genus of corals that lived during the Jurassic and Cretaceous periods. Its fossils have been found in Europe, Africa, North America, Asia and South America.
Dendrophylliidae is a family of stony corals. Most members are azooxanthellate and thus have to capture food with their tentacles instead of relying on photosynthesis to produce their food. The World Register of Marine Species includes these genera in the family:
Balanophyllia is a genus of solitary corals in the order of stony corals.
Caryophyllia is a genus of solitary corals in the family Caryophylliidae. Members of this genus are azooxanthellate and are found in the North Atlantic Ocean and the Mediterranean Sea at depths down to 2,670 metres (8,760 ft).
Stylaster is a genus of hydroids in the family Stylasteridae.
Leptopsammia is a genus of stony cup corals in the family Dendrophylliidae. Members of this genus are found at depths down to about 900 metres (3,000 ft). They are azooxanthellate, meaning that they do not contain symbiotic photosynthetic algae as do many species of coral.
Dipsastraea is a genus of stony corals in the family Merulinidae. Members of this genus are native to the Indo-Pacific region. They are zooxanthellate corals.
Heterocyathus is a genus of coral of the family Caryophylliidae.
Madracis is a genus of cnidarians belonging to the family Pocilloporidae. The genus has a cosmopolitan distribution.
Bathycyathus is a genus of cnidarians belonging to the family Caryophylliidae.
Coenocyathus is a genus of cnidarians belonging to the family Caryophylliidae.
Idmonea is a genus of bryozoans belonging to the family Idmoneidae.
