Well in keeping with Underwater Marine Life, for me these are rare. There are more than 3000 over species of this and some have’t been named as yet. Nudibranchs, also known as sea slugs, are some of the most beautiful and diverse creatures in the ocean.
Nudibranchs are essentially snails without shells, and their name literally means “naked gill”. In most species, the gills are prominently displayed on their dorsal surface.Some kinds of nudibranchs have a tuft of gills located on their backs at the posterior end, which are used only for respiration. Other kinds of nudibranchs have many finger-like structures on their backs called cerata, which function for gas exchange and often defense. Sea slugs have a pair of tentacles (called rhinophores) located on top of their heads, which biologists believe are used as sensory organs to assist in finding food and seeking a mate. The bright colouration seen in many species is believed to warn potential predators that the nudibranchs contain distasteful or even toxic compounds. Many of the dorid nudibranchs (Suborder Doridacea) are strongly scented, which is thought to be a chemical anti-predator warning.
But above all, this particular marine life is probably even more rare. Once was thought to be only found in Manado, Sulawesi, now can be found in various areas with difficulty. The problem is that it has an excellent camouflage method and is also very small, maximum length is 2cm. They are only found on gorgonians (sea fans) of the genus Muricella, in depths of 16-40m.

Well, if you can spot it – you have great eye sight. Otherwise, tell me, I will circle it for you later!
