A tunicate is an exclusively marine invertebrate animal, a member of the subphylum Tunicata (/ ˌtjuːnɪˈkeɪtə / TEW-nih-KAY-tə). This grouping is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term ...
Ciona. Species: C. intestinalis. Binomial name. Ciona intestinalis. (Linnaeus, 1767) Ciona intestinalis (sometimes known by the common name of vase tunicate) is an ascidian (sea squirt), a tunicate with very soft tunic.

Lahille, 1890. Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. [2] Ascidians are characterized by a tough outer "tunic" made of a polysaccharide. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%.
A salp (plural salps, also known colloquially as “sea grape”) or salpa (plural salpae or salpas[2]) is a barrel-shaped, planktonic tunicate in the family Salpidae. It moves by contracting, thereby pumping water through its gelatinous body; it is one of the most efficient examples of jet propulsion in the animal kingdom. [3]
Larvacean. Larvaceans or appendicularians, class Appendicularia, are solitary, free-swimming tunicates found throughout the world's oceans. While larvaceans are filter feeders like most other tunicates, they keep their tadpole-like shape as adults, with the notochord running through the tail. They can be found in the pelagic zone, specifically ...
Clavelina picta, common name the painted tunicate, is a species of tunicate (sea squirt), in the genus Clavelina (the "little bottles"). These animals, like all ascidians , are sessile filter feeders .
The predatory tunicate (Megalodicopia hians), also known as the ghostfish, [2] is a species of tunicate which lives anchored along deep-sea canyon walls and the seafloor. It is unique among other tunicates in that rather than being a filter feeder, it has adapted to life as an ambush predator. Its mouth-like siphon is quick to close whenever a ...
