Atriolum is a genus of colonial tunicates in the order Enterogona. These are marine animals found attached to the seabed or some other surface.
The World Register of Marine Species lists the following species in the genus: [1]
Ascidia is a genus of tunicates in the family Ascidiidae.
Herdmania is a genus of ascidian tunicates in the family Pyuridae.
Didemnidae, or Didemnidæ, is a family of colonial tunicates in the order Enterogona.
Microcosmus is a genus of tunicates in the family Pyuridae, containing the following species:
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.
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.
Pycnoclavella diminuta, known as the white-spotted sea squirt, white-spot ascidian, and white-spotted ascidian, is a species of tunicate, in the genus Pycnoclavella. Like all ascidians, these sessile animals are filter feeders.
Phallusia is a genus of tunicates of the family ascidians, which includes the following species:
Rhopalaea is a genus of tunicate belonging to the family Diazonidae.
Morchellium is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
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.
Pareugyrioides is a genus of marine tunicates.
Metandrocarpa 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.
