Dear Charles,

Thanks for the photos. I suspect your animal is Melibe engeli. Is this animal in an aquarium? I am trying to work out why it is opening and closing its oral hood like this, as though its catching things in the water. Although Melibe leonina from the west coast of Nth America does that [see message #15431], the other species all seem to 'feel' for bottom dwelling animals as they crawl along. Perhaps yours is crawling upside down on the water surface feeling for debris floating there?

Best wishes,
Bill Rudman
