  1. Hi Polly & welcome to Wetpixel --


    Do you have any close ups of the "worms"? They're more likely to be entwined basket stars/brittle stars or solenogastres (unusual shell-less, worm-like molluscs) than polychaetes. The circular orange area with triangular segments in the middle of the closest branch looks like the disc of a brittle star.

  2. Oh wow! That circle of fine hairs around the eye is fabulous! Never noticed it before.


    Art's opinion on similar shots was maybe Phycocaris simulans, maybe a new species of Phycocaris. I'll send this off to him, see if he known something more at this point.


    Davichin - same animal or a different one? They must be pretty territorial if it's the same one.

  3. I'd say a male & female either mating or the male carrying her around to make sure no other male can mate with her. Similar crabs are on the web as Leucosia pubescens - check out Teresa Zubi's site. In one of her shots both crabs are upside down & you can clearly see that one is male & one is female.



  4. So much prettier than any old shark! :lol:


    I would just call it Eunice sp for now. Hopefully someone will work up these giant eunicids someday. E. roussaei has been restricted to the Mediterranean & Adriatic Seas & I think aphroditois will end up being restricted to the Indian Ocean or even completely obliterated if type material can't be found.

  5. Such a big prey for such a tiny predator. It does seem that in the world of nudies it is not always the biggest who eats the smallest...


    Like we keep telling you guys, size isn't everything! :lol:


    According to the ever-informative Sea Slug Forum Gymnodoris inornata usually attacks its prey from behind, makes a hole in the prey's skin, and sucks out the internal organs. The prey shrivels away until it is an empty husk at which point the G. inornata will swallow what's left. So as long as it can stay attached it will be a successful predator on animals much larger than itself. http://www.seaslugforum.net/showall/gymninor

  6. That's one possibility. Callioplanidae and Planoceridae are 2 more families that have dorsal tentacles and very thin, transparent & cryptically patterned bodies. I don't really know flatworms & just picture key them like most people so I'm not willing to go past "flatworm" as an id.

    Cheerios, L

  7. You're half right - sea apples do feed on plankton and half wrong - it's not a sea apple. Those are echinoderms - holothuroids in the genera Paracucumaria and Pseudocolochirus. The critter in your video is a sea anemone in the family Actinodendronidae, possibly Actinostephanus haeckeli. The two images at the bottom are of haeckeli - http://web.nhm.ku.edu/inverts/adorian/actinodendronidae.htm Actinodendronid anemones have really powerful nematocysts and as you saw, are quite capable of catching fish.

  8. Much thanks! Tons of Eunice Roussaei found there, too. One was easily 8 feet long.


    I'd sure love to see some of those! The real name of the big caribbean eunicids is in doubt and it will require examining specimens to determine the correct name. Same for the other giant eunicids in other parts of the world - even the IP bobbitt. E. roussaei's range is now considered to be Adriactic, Mediterranean, etc. If you like going through scientific jargon (although this isn't as bad as most) there's a discussion about the issue here http://www.ots.ac.cr/tropiweb/attachments/...Polychaetes.pdf
