Amphiura is a large genus of brittle stars (Ophiuroidea) found in oceans worldwide, from tropics to Arctic and Antarctic regions.
Amphiura is a large genus that is currently divided into the following six subgenera: Amphioplus, Amphiura, Fellaria, Ophionema, Ophiopelte and Ophiopeltis. The once used subgenus Acrocnida has been elevated to a genus rank. The fossil record of the genus dates back to the Turonian ( Amphiura plana ). [1]
Extant species include: [2] [3]
Balaenidae is a family of whales of the parvorder Mysticeti that contains mostly fossil taxa and two living genera: the right whale, and the closely related bowhead whale.
A salp or salpa is a barrel-shaped, planktonic tunicate in the family Salpidae. It moves by contracting, thereby pumping water through its gelatinous body; it is one of the most efficient examples of jet propulsion in the animal kingdom. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
Parapterois is a genus of marine ray-finned fishes belonging to the family Scorpaenidae, the scorpionfishes. These fish originate from marine environments in the Indian Ocean or near it. The venomous Parapterois heterura is occasionally seen as an aquarium fish.
Amphiuridae are a large family of brittle stars of the suborder Gnathophiurina. Some species are used to study echinoderm development and bioluminescence.
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.
Crepidula atrasolea is a species of small sea snail, a slipper snail, a marine gastropod mollusk in the family Calyptraeidae, the slipper snails or slipper limpets, cup-and-saucer snails, and hat snails.
Bathyporeia elegans is a species of amphipod crustacean in the genus Bathyporeia which occurs in the northeastern Atlantic Ocean. It is unpigmented, and grows up to 6 millimetres (0.24 in) long.
Amphiura filiformis is a species of brittle star belonging to the family Amphiuridae. It is found on the seabed in the north east Atlantic Ocean and adjoining seas to a depth of 200 metres (660 ft). It digs itself a shallow burrow in the sand and waves its arms in the water above to suspension feed on plankton.
Catalaphyllia is a monotypic genus of stony coral in the family Euphylliidae from the western Pacific Ocean. It is represented by a single species, Catalaphyllia jardinei, commonly known as elegance coral. It was first described by William Saville-Kent in 1893 as Pectinia jardinei.
Amphipholis squamata, common names brooding snake star and dwarf brittle star, is a species complex of brittle stars in the family Amphiuridae.
Amphiura chiajei is a species of brittle star belonging to the family Amphiuridae. It is found in the northeastern Atlantic Ocean and adjoining seas to a depth of 1,000 metres (3,300 ft). It digs itself into the soft sediment of the seabed and raises its arms into the water above to suspension feed on plankton. It was first described by the British naturalist Edward Forbes in 1843, and was named for the Italian zoologist Stefano Delle Chiaje (1794–1860).
Acropora derawanensis is a species of acroporid coral that was first described by Carden Wallace in 1997. Found in tropical, shallow reefs sheltered from the waves in a marine environment, it is found at depths of 10 to 25 m on reef slopes. The species is rated as vulnerable on the IUCN Red List, with a decreasing population. It is not common but found over a large area, and is listed on CITES Appendix II. It is easily damaged.
Acropora donei is a species of acroporid coral that was first described by J. Veron and Carden Wallace in 1984. Found in fringing reefs and the upper slopes of shallow reefs, it occurs at depths of 5 to 20 m. The species is rated as vulnerable on the IUCN Red List, with a decreasing population, and is affected by disease. It is not common but found over a large area, and is listed under CITES Appendix II.
Acropora hoeksemai is a species of acroporid coral that was first described by Dr. Carden Wallace in 1997. Found in shallow reefs in a marine environment, it is found at depths of 8 to 20 m. It is listed as a vulnerable species on the IUCN Red List, and has a decreasing population. It is common, listed on Appendix II of CITES, and is found over a large range.
Acropora kosurini is a species of acroporid coral that was first described by C. C. Wallace in 1994. Found in marine, shallow reefs, it occurs at depths of 8 to 20 m. It is listed as a vulnerable species on the IUCN Red List, and it is believed to have a decreasing population. It is rare but found over a large area, and is listed on CITES Appendix II.
Acropora pharaonis is a species of acroporid coral that was first described by Milne-Edwards and Haime in 1860. Found in marine, tropical, reefs on slopes sheltered from wave action, it occurs at depths of between 5 and 25 m. It is classed as a vulnerable species on the IUCN Red List, and it has a decreasing population. It is common and found over a large area and is classified under CITES Appendix II.
Acrocnida brachiata, the sand burrowing brittlestar, is a species of brittle star in the family Amphiuridae. It occurs on the seabed in the northeastern Atlantic Ocean and the North Sea, living semi-buried in the sand with only its arm tips projecting.
