Brittle star genera

Gorgonocephalus, the '''Gorgon's heads or Gorgon's head basket stars', is a genus of marine basket stars in the class Ophiuroidea. Members of this genus are found in coldwater environments including the Arctic, the Antarctic, and deep-sea habitats. The scientific name comes from the Greek, gorgós meaning "dreaded" and -cephalus'' meaning "head", and refers to the similarity between these echinoids and the Gorgon's head from Greek myth with its coiled serpents for hair.

Asteroporpa is a genus of echinoderms belonging to the family Gorgonocephalidae.

Ophiura is a genus of echinoderms belonging to the family Ophiuridae.

Ophiocoma is a genus of brittle stars belonging to the family Ophiocomidae.

Asteronyx is a genus of echinoderms belonging to the family Asteronychidae.

Ophiothrix is a large genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to Arctic and Antarctic regions. At present a total of 93 Ophiothrix species have been recognized. It is considered as one of the most interesting genera because of the presence of its brilliant colors and associations with coral and sponges as well. This genus has been labelled particularly difficult with respect to taxonomy, due to a high degree of variability in characters that are described is a morphological aspect.

Ophiarachnella is a genus of echinoderms belonging to the family Ophiodermatidae.

Macrophiothrix is a genus of brittle stars.

Amphiodia is a genus of brittle stars belonging to the family Amphiuridae.

Ophiocomina is a genus of brittle stars belonging to the family Ophiotomidae. They are distributed worldwide.

Amphipholis is a large genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to Arctic and Antarctic regions. Some species have been used to study echinoderm development (Amphipholis kochii) and bioluminescence (the dwarf brittle star, Amphipholis squamata).

Acrocnida is a genus of brittle stars in the family Amphiuridae. The genus contains three members: Acrocnida brachiata, Acrocnida semisquamata, and Acrocnida spatulispina. There has also been observed hybridization between both Acrocnida brachiata and Acrocnida spatulispina. It is a fairly common genus, usually found along the coasts of Northwestern Europe, but with some species like semisquamata appearing around West Africa. Members of this genus primarily prefer intertidal and subtidal habitats, and they are less likely to be found in intertidal areas by comparison. This genus was not offici

Ophiomusium is a genus of brittle stars.

Amphilepis is a genus of brittle stars of the family Amphilepididae. It contains the following species: Amphilepis antarctica Amphilepis guerini Amphilepis ingolfiana Amphilepis mobilis Amphilepis neozelandica Amphilepis norvegica Amphilepis nuda Amphilepis papyracea Amphilepis patens Amphilepis pycnostoma Amphilepis sanmatiensis Amphilepis scutata Amphilepis tenuis Amphilepis teodorae

Ophioleuce is a genus of brittle stars.

Astrophyton muricatum, the giant basket star, is an echinoderm found in shallow parts of the tropical western Atlantic and throughout the Caribbean Sea and the Gulf of Mexico. It is the only species in the genus Astrophyton. During the day, it curls up into a tight ball shape to protect itself from predators. At night, it climbs to an elevated point to feed by extending its intricately branched feeding arms in a bowl-like shape in order to snare passing plankton and other organisms from the current.

Ophioplocus is a genus of brittle stars in the family Hemieuryalidae. The genus was first described by Thomas Lyman in 1861.

Ophionereis is a genus of echinoderms belonging to the family Ophionereididae.

Ophiomastix is a genus of echinoderms belonging to the family Ophiocomidae.

Trichaster is a genus of echinoderms belonging to the family Euryalidae.

Ophiopsammus is a genus of brittle stars within the family Ophiodermatidae.

Ophiotholia is a genus of brittle stars.

Hemipholis is a genus of brittle stars.

Ophiopholis is a genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to temperate regions.

Astrocladus is a genus of echinoderms belonging to the family Gorgonocephalidae.

Palaeocoma is an extinct genus of brittle stars that lived during the Middle Triassic to Early Jurassic Periods. Its fossils have been found in Europe.

Ophiohamus is a genus of brittle stars in the family Ophiacanthidae from New Caledonia. Timothy D. O'Hara and Sabine Stöhr circumscribed and named the genus in 2006; they described the type species Ophiohamus nanus in the same work. A second species, Ophiohamus georgemartini, was described by O'Hara and Caroline Harding in 2015. , those are the only two species recognized in this genus.

Monamphiura is a genus of brittle star echinoderms of the family Amphiuridae.

Ophiomusa is a genus of echinoderms, which includes sea urchins, sand dollars and sea cucumbers, belonging to the family Ophiolepididae. Ophiurida are similar to starfish; they both have a central disc and five arms sprouting from the disc. One of the main distinguishing factors of an Ophiuroid is its arms; the arms of an Ophiurida are longer, thinner, and distinctly separated in comparison to those of a sea star.

Stenaster is an extinct genus of brittle stars that lived from the Ordovician to the Silurian.

Geocoma is an extinct genus of brittle stars that lived in the Jurassic. Its fossils are known from Europe.
