Tibiania Perophora is a sea squirt genus in the family Perophoridae.
A colony consists of a number of zooids which bud off from a long slender stolon.
A Perophora colony consists of a system of stolons from which individual zooids arise at intervals.
Other distinguishing characteristics are that Perophora has a horizontal gut loop with a short rectum and a testis with usually one, but up to four lobes, situated in the gut loop.
In Ecteinascidia the gut loop is curved, the rectum long and the testis multi-lobed.
