Charitometridae is a family of crinoids or feather stars in the phylum Echinodermata.
The following genera are recognised by the World Register of Marine Species: [1]
Articulata are a subclass or superorder within the class Crinoidea, including all 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.
Ischnochiton is a genus of polyplacophoran mollusc.
Drillia is a genus of small sea snails, marine gastropod mollusks in the family Drilliidae.
Cyclostrema is a genus of sea snails, marine gastropod mollusks in the family Liotiidae.
Henricia is a large genus of slender-armed sea stars belonging to the family Echinasteridae. It contains about fifty species.
Lacuna is a genus of sea snails, marine gastropod mollusks in the family Littorinidae, the winkles or periwinkles.
Onoba is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Rissoa is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
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.
Capillaster is a genus of crinoids. It contains the following species:
Melithaea is a genus of octocorals in the family Melithaeidae. Members of the genus are commonly known as fan corals and are found in the tropical Indo-Pacific region. The type species is Melithaea ochracea.
Davidaster is a genus of crinoids. According to the World Register of Marine Species, a number of species that originally were included in the genus Nemaster are now included in Davidaster. Members of this genus have wedge-shaped arms, except for the basal ones, often longer than they are wide. The mouth is off centre and there are no pinnule combs after pinnule 3. The primary comb has the teeth widely separated and confluent with the lateral edge of the segment.
Metacrinus is a genus of stalked crinoids in the family Isselicrinidae. Members of this genus live on hard surfaces in deeper parts of the ocean. The genus has extant species and is also represented in the fossil record. Members of the genus grow to a maximum height of 60 centimetres (24 in) and are found in the eastern Pacific Ocean from Japan to Australia.
The elegant feather star is a species of crinoid in the family Tropiometridae.
Cinachyrella is a genus of marine sponges in the family Tetillidae.
Comatulidae is a family of comatulid crinoids. Since 2015, it replaces the family Comasteridae.
Colobometridae is a family of crinoids belonging to the order Comatulida. Members of this order are known as feather stars.
Dichrometra is a genus of echinoderms belonging to the family Mariametridae.
Zygometra is a genus of crinoids within the family Zygometridae. Members of this genus are found at depths of 10 to 162.5 meters in the Indo-Pacific around countries such as Australia, Indonesia, Malaysia and the Philippines.
