I changed it on 8 October 2011 into Melibe rangii Bergh, 1875.
In their recent publication list Gosliner & Pola (2012) Melibe engeli Risbec, 1937 as "distinct and recognizable",
they suggest that Melibe rangi Bergh, 1875 is "most likely a synonym of M. viridis".

The most unique attribute of the genus Melibe and so of Melibe engeli 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.
