Ascidiacea - Wikipedia
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 test or "tunic" made of the polysaccharide cellulose. Ascidians are found all over the world, usually in shallow water with salinities over ...

Ascidiacea - an overview | ScienceDirect Topics
The Ascidiacea, the largest class of the Tunicata, are fixed filter feeding organisms found in most marine habitats from intertidal to hadal depths. The class contains two orders: the Enterogona in which the atrial cavity (atrium) develops from paired dorsal invaginations, and the Pleurogona in which it develops from a single median invagination.
