Paratanaoidea is a superfamily of malacostracan crustacean. [1]
According to the World Register of Marine Species, the following families are accepted within Paratanaoidea: [1]
The following genera are regarded as Paratanaoidea incertae sedis , meaning their familial placement is uncertain: [2]
Mysidae is the largest family of crustaceans in the order Mysida, with over 1000 species in around 170 genera.
The crustacean order Tanaidacea make up a minor group within the class Malacostraca. There are about 940 species in this order.
Octocorallia is a class of Anthozoa comprising over 3,000 species of marine organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians within three orders: Alcyonacea, Helioporacea, and Pennatulacea. These organisms have an internal skeleton secreted by mesoglea and polyps with eight tentacles and eight mesentaries. As with all cnidarians these organisms have a complex life cycle including a motile phase when they are considered plankton and later characteristic sessile phase.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
The order Pygocephalomorpha is an extinct group of peracarid crustaceans. Pygocephalomorpha were abundant from the Carboniferous era until their extinction in the Permian era.
Leptocheliidae is a family of malacostracans in the order Tanaidacea. There are more than 30 genera and 140 described species in Leptocheliidae.
Apseudopsis is a genus of crustaceans belonging to the family Apseudidae. The genus has almost cosmopolitan distribution.
Typhlotanaidae is a family of crustaceans belonging to the order Tanaidacea.
Akanthophoreidae is a family of crustaceans belonging to the order Tanaidacea.
Anarthruridae is a family of crustaceans belonging to the order Tanaidacea.
Paramesochridae is a family of copepods belonging to the order Harpacticoida.
Parapseudidae is a family of crustaceans belonging to the order Tanaidacea.
Pseudotanaidae is a family of crustaceans belonging to the order Tanaidacea. The family contains one subfamily, Pseudotanainae, which contains five genera.
Algospongia is a class of small, calcified fossil organisms of uncertain taxonomic position, assigned in a comprehensive 2010 review to "Animalia" incertae sedis, but both prior to and post that to an unnamed phylum of Algae; other workers simply list them as Problematica. They occur in carbonate rocks of the Paleozoic era and their last representatives occur in the Late Permian geological period. Characteristic genera include Aoujgalia, Moravammina and the early-appearing Wetheredella, although the taxonomic validity of the last named genus has been disputed.
Agathotanaidae is a family of crustaceans belonging to the order Tanaidacea.
Araphura is a genus of malacostracan crustacean found in New Zealand.
Tanaellidae is a family of malacostracan crustacean.
Parapseudinae is an estuarine subfamily of crustacean in the order Tanaidacea.
Pseudotanais is a genus of tanaidacean crustacean.
Paleopneustina is a suborder of sea urchins of the order Spatangoida. Its taxonomy is still under investigation.
