Chiridota is a genus of sea cucumbers in the family Chiridotidae. It is an extant genus but some fossil species are known.
The following species are recognised in the genus Chiridota: [2]
Holothuria is the type genus of the marine animal family Holothuriidae, part of the class Holothuroidea, commonly known as sea cucumbers. Members of the genus are found in coastal waters in tropical and temperate regions. They are soft bodied, limbless invertebrates that dwell on the ocean floor and are usually detritivore. They resemble a cucumber in form. The genus contains some species that are harvested and sold as food.
Cidaris is a genus of pencil sea urchins.
Astropecten is a genus of sea stars of the family Astropectinidae.
Coelopleurus is an extant genus of echinoids with fossil records dating back to the Eocene, with remains found in Europe and North America.
Cucumaria is a genus of sea cucumbers.
Semicassis is a genus of medium-sized predatory sea snails, marine gastropod molluscs in the subfamily Cassinae within the family Cassidae, the helmet snails and bonnet snails.
Spatangus is a genus of heart urchins in the Spatangidae family. The genus is synonymous with the previously recognised genera Prospatangus Lambert, 1902 and Spatagus. There are nine recognised species. The type species is Spatangus purpureus Müller, 1776 by subsequent designation.
Synaptidae is a family of sea cucumbers that have no tube feet, tentacle ampullae, retractor muscles, respiratory trees, or cuvierian tubules. They also lack radial canals of the water-vascular system, with only the circumoral ring present.
Cucumariidae is a family of sea cucumbers, marine animals with elongated bodies, leathery skins and tentacles that are found on the sea bed.
Phyllophoridae is a family of sea cucumbers, marine invertebrates with elongated bodies, leathery skins and feeding tentacles.
Beroe, commonly known as the cigar comb jellies, is a genus of comb jellies in the family Beroidae.
Chiridotidae is a family of sea cucumbers.
The Diphyidae are a family of siphonophores. These are colonial siphonophores with two nectophores arranged one behind the other. The front one includes a somatocyst, while the hind one does not. The somatocyst often contains an oil droplet for buoyancy control. A nectosac in each nectophore allows the organism to swim efficiently.
Opheodesoma is a genus of sea cucumbers in the family Synaptidae.
Psolus is a genus of sea cucumbers in the family Psolidae, marine animals with long bodies, leathery skins and tentacles, that inhabit the sea bed.
Aegina citrea is a genus of hydrozoans in the family Aeginidae.
Pteraster is a genus of sea stars in the family Pterasteridae.
Pseudocnus is a genus of sea cucumbers.
Leptopentacta is a genus of sea cucumbers in the family Cucumariidae.
Thyone is a genus of sea cucumbers in the family Phyllophoridae.
