It is Melibe sp. 3 in IPN at page 331
Let me quote: " This squat species is uniformly dark brown with thick cerata covered with minute light spots. The rhinophoral sheaths are short and broad and the oral hood is small relative to the size of the animal." and "Size: Length 120 mm."
Let me quote Gosliner & Pola (2012):"Melibe coralophilia has several unique morphological attributes that clearly distinguish it from all other species of Melibe. It is the only species with a large body and a relatively small oral hood. It also is unique in having a dorsal crest of densely arranged tubercles." Unique is also the attitude to hold the egg-mass on the right side of the body.
Gosliner & Pola (2012) named it in their recent publication Melibe coralophilia as it has been found in assosiation with Porites and Heliopora corals.
The most unique attribute of the genus Melibe is their method of feeding. They have no radular teeth and but have developed the oral veil into a large veil or "fish net" which they use to constantly scan the substrate as they crawl along. When the sensitive papillae on the inner edge of the oral veil touch a small crab or crustacean the edge of the veil is rapidly contracted, trapping the prey, which is then ingested.
This species was posted on 21 April 2011 at these websites as Melibe sp. A Genus: Rang, 1829, and on 8 October 2011 changed into
Melibe sp. 01 Genus: Rang, 1829,
for some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even if '01' looks a little bit stupid, and then was only the genus italic written.
