Here's another... Anyone have any idea on this one? It is maybe 1/8-inch long and travels quickly (vertically) using what I can best describe as a pair of Dumbo ears. I see them quite often so I'm assuming they are quite abundant.

In one of the videos I have from Nat'l Geographic, Ocean Drifters, there's a similar creature which they mention is some type of post-larval mollusk. Any IDeas?

There is one more photograph of it in one of my stories here.

Hi there
I would ay it's a pelagic opisthobranch, but an adult, not juvenile
there are two major groups, Thecosomes and Gymnosomes (= Pteropods), I would tentatively suggest it's a gymnosome, but try Wrobel & Mills (1998), Pacific Coast Pelagic Invertebrates, there is also a more scientific book on pelagic gastropods, can't recall the author and the exact title ... hmmm
:lol:
