Ophiotomidae is a family of brittle stars. [2] It was originally introduced as a subfamily Ophiotominae under the family Ophiacanthidae. [1] The family has a worldwide distribution. [3]
There are six genera: [2]
Brittle stars, serpent stars, or ophiuroids are echinoderms in the class Ophiuroidea, closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to 60 cm (24 in) in length on the largest specimens.
Actiniidae is the largest family of sea anemones, to which most common, temperate, shore species belong. Most members of this family do not participate in symbioses with fishes. Three exceptions are the bubble-tip anemone, snakelocks anemone and Urticina piscivora.
Astropecten is a genus of sea stars of the family Astropectinidae.
Amphiuridae are a large family of brittle stars of the suborder Gnathophiurina. Some species are used to study echinoderm development and bioluminescence.
Ophiopholis is a genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to temperate regions.
Ophiotrichidae are a family of ophiurid brittle stars within the suborder Gnathophiurina.
Arminidae is a family of sea slugs, marine gastropod mollusks in the superfamily Arminoidea.
Ophioderma is a genus of brittle stars in the family Ophiodermatiidae.
Christian Frederik Lütken, was a Danish zoologist and naturalist.
Haloclavidae is a family of sea anemones. Members of the family are found worldwide and many live largely buried in soft substrates with only their oral disc and tentacles protruding.
Ophiopsila is a genus of brittle star belonging to the family Ophiocomidae. Many species are bioluminescent.
Ophiactis is a genus of brittle stars (Ophiuroidea).
Ophiacanthidae is a family of brittle stars. Axel Vilhelm Ljungman circumscribed this taxon in 1867; he initially named the subfamily Ophiacanthinae within the family Amphiuridae. Gordon L. J. Paterson promoted its rank to family in 1985.
Actinostolidae is a family of sea anemones in the order Actiniaria. Members of this family are deep sea species, with some occurring at hydrothermal vents.
Euryalidae is a family of echinoderms belonging to the order Euryalida.
Hemieuryalidae is a family of echinoderms belonging to the order Amphilepidida.
Ophiacanthida is an order of echinoderms belonging to the class Ophiuroidea.
Ophiura is a genus of echinoderms belonging to the family Ophiuridae.
Ophiomusa is a genus of echinoderms belonging to the family Ophiolepididae that includes: sea urchins, sand dollars and sea cucumbers. 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.
Hemipholis is a genus of brittle stars.
