Clavelina moluccensis, the bluebell tunicate Botrylloides violaceus showing oral tentacles at openings of buccal siphons. About 3,000 species of tunicate exist in the world's oceans, living mostly in shallow water. The most numerous group is the ascidians; fewer than 100 species of these are found at depths greater than 200 m (660 ft). [12]

A salp (pl.: salps, also known colloquially as “sea grape”) or salpa (pl.: 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]
Thaliacea is a class of marine chordates within the subphylum Tunicata, comprising the salps, pyrosomes and doliolids. Unlike their benthic relatives the ascidians , from which they are believed to have emerged, thaliaceans are free-floating ( pelagic ) for their entire lifespan.
The full development of Oikopleura dioica and the fate of its cell lineages have been well-documented, providing insight into larvacean anatomy. [11] Being a model organism, most of our knowledge on larvaceans comes from this specific taxon. Variations in body shape and anatomy exist between families, [12] although the general body plan stays ...
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 .
Ciona intestinalis (sometimes known by the common name of vase tunicate) is an ascidian (sea squirt), a tunicate with very soft tunic. Its Latin name literally means "pillar of intestines", referring to the fact that its body is a soft, translucent column-like structure, resembling a mass of intestines sprouting from a rock. [ 1 ]
