Nudi Series & Quiz: Chromodoris (1)

Marine Life mediumThe 13th edition of Marine Life monthly post is sponsored by Dive InspireDive Inspire offers unique products inspired by the beautiful and colorful marine life from our oceans. You can win one of their products if you can answer the quiz correctly. Trust me, you don’t have to be a marine biologist to join the quiz. Let’s get to know the nudibranch and grab the gifts!

Nudi is a nick name for the Nudibranch. You may think it is related to naked, yes, it is! Nudibranch means “naked gill”. It is an invertebrate animal from the molluscs group that can be found anywhere in the oceans. They are more diverse in tropical seawater like in Thailand, the Philippines, Malaysia and Indonesia. There are more than 100 groups of Nudibranch; and Chromodoris is one of the more popular ones because it has a large number of species. Chromodoris is also called Goniobranchus.

Chromodoris has dorsal appendages called CERATA that function as a respiratory and digestive system. Its horns are called RHINOPHORE and contains the “nose” of the nudibranch. It functions as a sensory receptor to “chemical scents” and water current. Its MANTLE is body part of nudibranch that resembles a cloak.

Nudibranch Anatomy

According to database, there are 85 species identified as part of Chromodoris. The common things of these species are: they are able to release toxic, feed on sponges and store the sponges chemicals on their mantle. I don’t think the fish will find this nudibranch as tasty prey. However some nudibranch species are carnivore, they eat other nudibranch, usually from different species. Sort of cannibalism of nudi’s world.

The Fantastic Four Species of Chromodoris

I haven’t seen all 85 species of Nudibranch Chromodoris yet, but would love to. Perhaps it will be too optimistic to see all species in my future dives. Four Chromodoris species at once should be a good start. These fantastic four Chromodoris are commonly seen in Indo-Pacific region. Their images are as following (Please click the image for large version):

Their species names and descriptions are as following – (not in the order of the images):

Chromodoris magnifica, it has the orange band around the mantle and three black lines on top its body. Its rhinophores and cerata are both having orange colors.

Chromodoris willani, this nudibranch has bluish white or translucent white background color and black longitudinal stripes. Its cerata and rhinophores are speckled white.

Chromodoris annae has black longitudinal lines on top of blue colored background on its mantle. It has yellowish close to orange colored border on its mantle. Its cerata and rhinophores have orange colors.
