Trapania cirrita is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.
This species was first described from South Africa.
This goniodorid nudibranch is translucent brown in colour, with an irregular network of short white lines on the body.
Trapania cirrita probably feeds on Entoprocta which often grow on sponges and other living substrata.
