Corals are colonial marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
Parrotfish are a group of fish species traditionally regarded as a family (Scaridae), but now often treated as a subfamily (Scarinae) or tribe (Scarini) of the wrasses (Labridae). With roughly 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 27 species of Old World coral snakes, in three genera, and 83 recognized species of New World coral snakes, in two genera. Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus Micrurus. Meanwhile, snakes of the genus Micruroides have never caused a medically significant bite.
Micrurus is a genus of venomous coral snakes of the family Elapidae.
Alpheidae is a family within the infraorder caridea characterized by having asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound.
Acropora is a genus of small polyp stony coral in the phylum Cnidaria. Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. Acropora species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin of a reef.
Apo Island is a volcanic island covering 74 hectares in land area, 7 kilometers off the southeastern tip of Negros Island and 30 kilometers south of the Negros Oriental capital of Dumaguete in the Philippines. The name "Apo" means "elder" or "respected ancestor" in the Visayan languages.
Porites is a genus of stony coral; they are small polyp stony (SPS) corals. They are characterised by a finger-like morphology. Members of this genus have widely spaced calices, a well-developed wall reticulum and are bilaterally symmetrical. Porites, particularly Porites lutea, often form microatolls. Corals of the genus Porites also often serve as hosts for Christmas tree worms.
Euphyllia is a genus of large-polyped stony coral. Several species are commonly found in marine aquariums. The genus includes the following species:
Gemmocystis is a genus of apicomplexans.
Achaeus japonicus, sometimes known as the orang-utan crab, is a crab of the family Inachidae which can be observed in tropical waters of the central Indo-Pacific.
Ancylomenes longicarpus is a species of shrimp found from the Red Sea to the Western Pacific. Its tiny body is transparent with white and purple spots on tail and white line between eyes. It is often associated with corals from genera Xenia, Plerogyra and anemones Entacmaea quadricolor, Heteractis crispa.
Euphylliidae are known as a family of polyped stony corals under the order Scleractinia.
Diogenes heteropsammicola is a species of hermit crab discovered during samplings between 2012 and 2016 in the shallow waters of the Japanese Amami Islands. This D. heteropsammicola is strongly associated with the walking corals. This hermit crab species is unique due to the discovery that they use living, growing coral as a shell. The live in the inside of the coral and vary from other types of hermits. Crustaceans of this type commonly replace their shell as the organism grows in size, but D. heteropsammicola are the first of their kind to use solitary corals as a shell form. Heteropsammia and Heterocyathus are the two solitary corals that this hermit species has been observed as occupying. These two coral species are also used as a home by symbiotic Sipuncula of the genus Aspidosiphon, which normally occupy the corals that were previously occupied by crabs.
Lithophyllon is a genus of stony corals in the family Fungiidae.
Grape coral may refer to two different species of sea anemone:
Bubble coral may refer to two different species of sea anemone:
Heterocyathus is a genus of coral of the family Caryophylliidae.
Heteropsammia is a genus of apozooxanthellate corals that belong to the family Dendrophylliidae.
Pectinia is a genus of corals belonging to the family Merulinidae.
