updated Sep 12

Where seen? This extremely well camouflaged nudibranch was seen among Sargassum seaweeds (Sargassum sp.) at St. John's Island.

Features: About 3cm long. It has a pair of 'flaps' (mantle lobes) in the middle of the body. There are fluffy structures (dendritic gill-like structures) inside the mantle lobes. The brush-like rhinophores are tiny and are at the tip of a huge rhinophore stalk. Along the sides of the body it has a few bright blue spots and white spikes.

What does it eat? This nudibranch grazes tiny hydroids that grow on seaweeds.
