Species: [1]
Ascidia is a genus of tunicates in the family Ascidiidae.
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. A few species, including Pyura chilensis are commercially fished.
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 sea squirts, 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 an order 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.
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.
Cnemidocarpa is a genus of ascidian tunicates in the family Styelidae.
Polyandrocarpa is a genus of ascidian tunicates in the family Styelidae.
Stolonica is a genus of ascidian tunicates in the family Styelidae.
Polycitor is a genus of tunicates belonging to the family Polycitoridae.
Diplosoma is a genus of tunicates belonging to the family Didemnidae.
Cystodytes is a genus of tunicates belonging to the family Polycitoridae.
Distaplia is a genus of tunicates belonging to the family Holozoidae.
Polysyncraton is a genus of tunicates belonging to the family Didemnidae.
