Colourful Nudi

UNDERWATER SUBJECT

This is a Cuthona yamasui, which is a species of sea slug, or nudibranch. They are a shell-less marine Gastropod mollusc. I found this colourful little guy (about 3 cm long) while doing a night dive in the Komodo National Park. It appeared to be eating the white Stinging Hydroid (Aglaophenia) it was sitting on.
