updated Oct 2016
Where seen? This nudibranch with bead-like bumps is sometimes seen on on our Northern shores among seagrasses and seaweeds. It appears to be seasonally common, often with many seen during a single visit.

Features: 4-5cm long. Hard broad body with rounded bumps all over it like beads with a broad band down the centre of the body which has fewer or no bumps and is usually darker in colour. The body doesn't fall apart when handled. Gills feathery and orange. The underside is pale with some smudged darkish blotches on the edges. The narrow foot is plain.
