Mayotte, Mtsanga Mbouanatsa, less 1 m, 6 October 2012, size : 30 mm
This nudibranch is well hidden on the substrate
It mimics an encrusting ascidian....
A strange behavior, all the inside face of the cerata are visible...
Never the outside face...
If somebody make a photo with all the outside face, it would be interesting to see the effect...
The same specimen crawling on the substrate...with the "outside face" forward...
