I Am The Orange One.....
The bright orange nudibranch that I came across during The Hantu Bloggers dive in August has been IDed.
Dr Bill Rudman from The Sea Slug Forum has IDed it as the color form of Phestilla melanobrachia. This nudibranch comes in Black too.
It is believed that the colour of the nudibranch matches the colour of the dendrophylliid coral (Tubastrea, Dendrophyllia) on which they are feeding. Hmmm.....so will the black one turn orange after feeding?
