The outer covering of the [tunicate] is a thick, tough, sometimes gelatinous membrane, the "tunic" or "test", secreted by the underlying epithelium and attached to the inclosed body only at the siphons. In some tunicates the test is so transparent that practically all of the internal organs are visible through it.

CONT

Urochordates ... are enclosed in a tough cellulose-like tunic (hence the common name tunicate).

OBS

Hemichordates and most urochordates are... filter-feeders, moving water through their gill slits, but are sessile as adults. When ascidian tunicates metamorphose, the motochord is resorbed.
