The World Register of Marine Species includes these species in this genus:- [1]
The Clionidae are a family of sea angels, which are a group of pelagic marine gastropods.
A salp or salpa is a barrel-shaped, planktic tunicate. It moves by contracting, thereby pumping water through its gelatinous body, one of the most efficient examples of jet propulsion in the animal kingdom. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
Botryllus is a genus of colonial 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.
Eusynstyela is a genus of ascidian tunicates in the family Styelidae.
Halocynthia is a genus of ascidian tunicates in the family Pyuridae. Species such as H. roretzi are used as food.
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.

Golfingiidae is a family of peanut worms.
Phascolionidae is a family of peanut worms.
Styelidae is a family of ascidian tunicates.
Thalassema antarcticum is a species of marine echiuran worm. This species is different from others in its genus that also have continuous longitudinal muscles by its lack of papillae on the body.
Synoicum is a genus of colonial sea squirts, tunicates in the family Polyclinidae.
Distomus is a genus of ascidian tunicates in the family Styelidae.
Stolonica is a genus of ascidian tunicates in the family Styelidae.
Thalassematidae is a family of spoonworms in the suborder Echiurida.
Anelassorhynchus is a genus of spoonworms in the subclass Echiura.
Thalassema steinbecki is a species of marine echiuran worm. It is found in the northeast Pacific Ocean. This species was formally described in 1946 by the American marine biologist Walter Kenrick Fisher (1878-1953), the specific name honours the American novelist John Steinbeck (1902-1968) who led the expedition which collected the type specimens.
