Corella is a genus of sea squirts belonging to the family Corellidae. The genome of Corella inflata has been sequenced which has provided insight into tunicate evolution [2]
The World Register of Marine Species includes the following species in this genus: [1]
Ascidia is a genus of tunicates in the family Ascidiidae.
Microcosmus is a genus of tunicates in the family Pyuridae, containing the following species:
Didemnum is a genus of colonial tunicates in the family Didemnidae. It is the most speciose genus in the didemnid family. Species in this genus often have small calcareous spicules embedded in the tunic and form irregular or lobed colonies. Some Didemnum species, including Didemnum vexillum and Didemnum perlucidem are considered invasive species. In early 2006, Didemnum vexillum was found covering a 230 km2 area of cobble habitat in Georges Bank off the coast of New England, and is classified as an invasive species of greatest concern in coastal areas throughout Europe, New Zealand, and North America. Didemnum sp. invasions have also been recorded in Canada, the Mediterranean, and the Netherlands.
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.
Eusynstyela is a genus of ascidian tunicates in the family Styelidae.
Phlebobranchia is an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886.
Halocynthia is a genus of ascidian tunicates in the family Pyuridae. Species such as H. roretzi are eaten in parts of Asia as a delicacy.
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.
Phallusia is a genus of tunicates of the family Ascidiidae, which includes the following species:
Polycarpa is a genus of ascidian tunicates in the family Styelidae.
Rhopalaea is a genus of tunicates belonging to the family Diazonidae. The genus has a cosmopolitan distribution in warm and temperate oceans.
Molgulidae is a family of tunicates in the class Ascidiacea. Following a revision in 2007, the family Hexacrobylidae was synonymized with Molgulidae.
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.
Aplidiopsis is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
Eugyra are marine tunicates.
Cnemidocarpa is a genus of ascidian tunicates in the family Styelidae.
Gynandrocarpa is a genus of ascidian tunicates in the family Styelidae.
Culeolus is a genus of ascidian tunicates in the family Pyuridae.
