Botryllus elegans is a species of colonial ascidian tunicates in the family Styelidae. It is found in Mozambique and South Africa.
Ascidiacea, commonly known as the ascidians or sea squirts, 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 a polysaccharide.
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.
Ciona is a genus of sea squirts in the family Cionidae.
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.
Botryllus is a genus of colonial ascidian tunicates in the family Styelidae.
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.
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.
Styela angularis is a solitary, hermaphroditic ascidian tunicate that is found along the coast of Southern Africa from Lüderitz Bay in Namibia to the Eastern Cape.
