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 an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886.

The posterior part of the abdomen contains the heart and gonads, and is typically larger than in other sea squirts.
