Yellow foot nudibranch
Thordisa villosa
Family Dorididae
updated Oct 08

Where seen? This rather boring but large nudibranch is sometimes seen on our Northern shores among coral rubble. It appears to be seasonally common.

Features: 8-10cm long. The upperside of the broad hard body looks like coral rubble in colour and texture: it has small tapering finger-like structures (papillae). The underside and small foot is yellow with brown or black spots.
The body doesn't fall apart when handled. Tiny rhinophores and small feathery gills.
