The following species are currently recognized: [1]
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.
Articulata are a subclass or superorder within the class Crinoidea, including the only living crinoid species. They are commonly known as sea lilies or feather stars. The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an entoneural system. Articulata first appeared in the fossil record during the Triassic period although other, now extinct crinoid groups, originated in the Ordovician.
Lamiinae, commonly called flat-faced longhorns, are a subfamily of the longhorn beetle family (Cerambycidae). The subfamily includes over 750 genera, rivaled in diversity within the family only by the subfamily Cerambycinae.
Admiral Pelham Aldrich was a Royal Navy officer and explorer, who became Admiral Superintendent of Portsmouth Docks.
Eupithecia satyrata, the satyr pug, is a species of moth of the family Geometridae. It was described by Jacob Hübner in 1813. It is found from Ireland, through northern and central Europe east to all of Russia and central Asia and western Siberia to Tibet. It is also present in North Africa and North America.
Bathycrinidae is a family of echinoderms in the class Crinoidea. It contains the following genera and species:
Eupitheciini is a tribe of geometer moths under subfamily Larentiinae, often referred to as pugs. The tribe was described by Tutt in 1896.
Antedonidae is a family of crinoids or feather stars in the phylum Echinodermata. Members of the family are unstalked and have ten feathery arms. They can move about freely and have clawed cirri to attach them temporarily to structures.
Bathycrinus aldrichianus is a species of sea lily, a crinoid in the family Bathycrinidae. It is native to deep water in the North Atlantic Ocean. It was first described by the Scottish marine zoologist Charles Wyville Thomson and named in honour of Pelham Aldrich, a British naval officer and explorer. It is believed to be the crinoid living at the greatest depth.
Ophiactis is a genus of brittle stars (Ophiuroidea).
Bathycrinus australis is a species of sea lily, a crinoid in the family Bathycrinidae. It is native to deep water in the Antarctic Ocean. It was initially identified as Bathycrinus aldrichianus by Philip Herbert Carpenter following the 1872-1876 HMS Challenger expedition. It was later distinguished as a new species by the American zoologist Austin Hobart Clark.
Bathycrinus gracilis is a species of sea lily, a crinoid in the family Bathycrinidae. It is native to the North Atlantic. It was described by Charles Wyville Thomson.
Bathycrinus mendeleevi is a species of sea lily, a crinoid in the family Bathycrinidae. It is native to the Pacific Ocean west of South America. It was described by A. N. Mironov.
Ophiomusium is a genus of brittle stars.
Myriotrochus is a genus of sea cucumbers. The following species are recognised in the genus Myriotrochus:
The pourtalesiids (Pourtalesiidae) are a family of irregular sea urchins that live in the deep sea. They are secondarily bilateral-symmetrical and like other representatives of the taxon Holasteroida they lack the lantern of Aristotle, which is typical for many other sea urchins. The genus Pourtalesia was named after Louis-François de Pourtalès who first collected these animals while dredging at a depth of 600 m. The family is known already from the Upper Cretaceous (Maastrichtian) and is distributed worldwide.
Endoxocrinus is a genus of echinoderms belonging to the family Pentacrinitidae.
Hyocrinidae is a family of echinoderms belonging to the order Hyocrinida.
