Polyclinum is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
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.
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. It is a cluster of identical cells (clones) on the surface of a solid medium, usually derived from a single parent cell, as in bacterial colony. In contrast, a solitary organism is one in which all individuals live independently and have all of the functions needed to survive and reproduce.
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.

Polyclinum aurantium is a species of colonial sea squirt, a tunicate in the family Polyclinidae. It is native to shallow water in the northeastern Atlantic Ocean and Mediterranean Sea.
Polyclinum planum, is a compound ascidian commonly known as the Elephant Ear Tunicate. It is an ascidian tunicate in the family Polyclinidae. Ascidians are also known as sea squirts.
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.
Microcosmus is a genus of tunicates in the family Pyuridae, containing the following species:
Botrylloides is a genus of ascidian tunicates in the family Styelidae.
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.
Phallusia is a genus of tunicates of the family ascidians, which includes the following species:
