Two views of a pelagic nudibranch. No idea what kind it is though! The rhinopores at the bottom are clear enough but I have no idea what any of the other bits are. Or which view is from the side and which from the top/bottom. Pics from Balayan Bay, Anilao #MarineLife #Invertebrates #Blacwater - ThreadSky

ah, now that I see the rhinophores..perhaps both are Phylliroe

xenomatt.bsky.social•23 days ago

Thanks! They're both pics of the same individual critter.

The one with the two projecting bits is Phylliroe not sure about the other perhaps @rebeccarhelm.bsky.social knows? https://www.inaturalist.org/observations/274161003

I would agree. There is another genus of pelagic nudibranch but it’s not quite as fishy shaped

Thanks!

Is it mimicking a fish for some reason, or is that just coincidence?

echinoblog.bsky.social•23 days ago

there is probably some convergence there.. here's more https://deepseanews.com/2015/11/meet-the-sea-slug-that-looks-like-a-fish-lives-in-the-deep-sea-and-glows/

Thanks for that! I hadn't realized the odd lump at the front was its foot... and the pics in that article give me something to aim at next time I meet one :)
