Hooded Nudibranch - a species of sea slug, specifically a predatory nudibranch. The body of this nudibranch is translucent. It is usually colorless to pale yellow or green, with opaque brown hepatic diverticula. It has a large expandable oral hood, fringed with sensory tentacles, which it opens and throws forward in order to catch food. A single pair of rhinophores on the hood are rounded and earlike. 4-6 pairs of flat paddle shaped cerata run along its dorsum in two rows.
