I've found a unidentified sea slug. I've attached the image.
I felt it is Noumea simplex, but the rhinophore clubs are tipped in deep orange in N. simplex, but the whole color of the rhinophore is orange in my animal. I've found Noumea decussata on your Forum. The color of the rhinophore are the same. However the pattern of the gill is uncertain. it's not clear in my photo.
One thing I am wondering is that this sea slug can retract its rhinophores completely. It seems very sensitive. As far as I observe, N. simplex usually do not retract their rhinophore. Or I should say, they are not as sensitive. That may be why I do not see it?

I'm pretty sure that this is N. decussata. I am not sure if it is more sensitive than N. simplex .
Can you let me know where you photographed your animals so I can add it to the data please?
