Bathypyura is a genus of ascidian tunicates in the family Pyuridae.
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Ascidiacea is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer "tunic" made of the polysaccharide cellulose.
A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata. It is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords. The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. They are the only chordates that have lost their myomeric segmentation, with the possible exception of the seriation of the gill slits.
Species within the genus Bathypyura include: [1]
Herdmania is a genus of ascidian tunicates in the family Pyuridae.
Sorberacea are a monofamilial class of benthic Tunicates. They superficially resemble sea squirts but prey on invertebrates such as crustaceans. They also have some unique physical features that distinguish them from the ascidiaceans, including a severely reduced pharynx, the retention of the dorsal nerve cord as adults, the superficial position of their ganglion and the unique histology of the cells of their digestive tracts. The branchial syphon is large and surrounded by six large lobes; the cloacal syphon is small. They live exclusively in deep water and range in size from less than one inch (2 cm) to 2.4 inches (6 cm).
