Veering Magnificent Chromodoris Nudibranch

Chromodoris magnifica, the Magnificent Chromodorid

This nudibranch is veering sharply to its left, but at a snail's pace. The rhinophores look kind of like horns, but they are more like an inside-out nose. The reddish gill at back is like an inside-out lung; or is a lung a gill that has been turned inside-out, for use in air? Beneath the skirt of their mantle you can see their mouth parts to the right, and entrance/exit of the reproductive organs at center. Nudibranchs are hermaphrodites. Chromodoris are a major genus among them; most of them have stripes. Below the skirt is the foot, with black and white stripes like the top of the mantle. This creature was at about 70 feet, off the coast at the Crystal Blue Resort in Anilao.
