WhyReef - Lifestyle
Like snails and other sea slugs, the magnificent sea slug is a gastropod. Most gastropods have a hard shell outside (not the magnificent sea slug, though) and a muscular foot that they use to move around.
Though it can’t see, it has two tentacles on its head called rhinophores and two near its mouth called oral tentacles, which allow it to smell, taste, and feel its way around the reef. The feathery parts on the back of its body are gills that it uses to breathe in water.

WhyReef - Threats
Chromodoris magnifica can reach a maximum size of 5 cm length. The body is elongate with a foot which is distinct from the upper body by a skirt like mantle hiding partially the foot. The branched gills and the rhinophores are orange colour and can be withdraw in specific pockets under the skin in case of danger. The specific epithet magnifica in Chromodoris magnifica means magnificent, so-named because of this nudibranch's striking, vibrant colors.
The background colour of the body is bluish which intensity varies from a specimen to another. On the mantle, the bluish area is outlined by two continuous black lines and a median continuous line cross it also. These bluish parts are often marked with dash-like black lines. The margin of the mantle is bordered with a large white band with a central orange colour line, the width of these lines is variable for each specimen.
The foot has three black continuous longitudinal lines. Its background colour is the same as its mantle. The margin of basis foot is outlined by an orange and a white line.
