Stolonica is a genus of ascidian tunicates in the family Styelidae.
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 Stolonica include: [1]
Stolonica socialis is a species of tunicate or sea squirt in the family Styelidae. It is native to the northeastern Atlantic Ocean where it lives on the seabed.
Species names currently considered to be synonyms:
Distomus variolosus is a species of tunicate or sea squirt in the family Styelidae. It is native to the northeastern Atlantic Ocean where it lives on the seabed.
Pyura is a large genus of sessile ascidians that live in coastal waters at depths of up to 80 m (260 feet). Like all ascidians, Pyura are filter feeders.
Microcosmus is a genus of tunicates in the family Pyuridae, containing the following species:
Styela is a genus of tunicates. Styela clava, an edible species, is known as an invasive species in some areas.
Molgula, or sea grapes, are very common, globular, individual marine tunicates roughly the size of grapes.
Clavelina is genus of tunicates, containing the following species:
Eusynstyela is a genus of ascidian tunicates in the family Styelidae.
Phlebobranchia is a suborder of sea squirts in the class Ascidiacea.
Stolidobranchia is an order of tunicates in the class Ascidiacea. The group includes both colonial and solitary animals. They are distinguished from other tunicates by the presence of folded pharyngeal baskets. This provides the etymology of their name: in ancient greek, στολίς, ίδος means the "fold" of a cloth. Stolidobranchian sea squirts are also characterized by the complete absence of an abdomen. The abdominal organs of other tunicates are instead located to one side of the pharyngeal basket in this group.
Aplousobranchia is a suborder of sea squirts in the class Ascidiacea. They are colonial animals, and are distinguished from other sea squirts by the presence of relatively simple pharyngeal baskets. This provides the etymology of their name: in ancient greek, ἁ.πλοος-ους (ha.ploos-ous) means "simple". The posterior part of the abdomen contains the heart and gonads, and is typically larger than in other sea squirts.
Polycarpa is a genus of ascidian tunicates in the family Styelidae.
Styelidae is a family of ascidian tunicates.
Polyclinum is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
Synoicum is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
Eugyra are marine tunicates.
Pareugyrioides is a genus of marine tunicates.
Alloeocarpa is a genus of ascidian tunicates in the family Styelidae.
Cnemidocarpa is a genus of ascidian tunicates in the family Styelidae.
Polyandrocarpa is a genus of ascidian tunicates in the family Styelidae.
