Last Saturday (May 29th), I took this foto, at about 50fws, during an open water dive, a few miles off the LA coastline. The animal is, I believe, a C. affinis. On close inspection, it appears to have a tiny hitchhiker, about 1/4 inch long. Perhaps a type of flat worm or a sea slug. Not sure what it is. Dave Behrens isn't quite sure himself. Anyone want to hazard a guess or provide an educated ID?

Oh Kevin, how can you insult the noble name of worm this way? It's an amphipod!

Oh disgraceful egg on my countenance! May the Most Revered Royal Polychaete Gods lash me a thousands times with a flatworm belt and deign to accept my most humble apologies. :oops: k;-)
AMPHIPOD?!^@$%# sheesh...
Yet, I discern no hint of segmentation that would be characteristic of an amphiod.
Reason I thought it might be a flatworm (which I mistook for a sea slug):

I'm sure the Polychaete Gods will accept such a heart-felt apology!

Of course, the egg will be on my face if I'm wrong :lol: I had forgotten about that worm (didn't I find the name for you?). I'll send it to some pod friends and see if they agree or if I'll be the next one kneeling in shame.
Cheers, Leslie

Don Cadien had this to say " It is an amphipod, probably a hyperiid in the genus Scina (at least that is what the antennal peduncles suggest)."

I found a good article for you - with UW pics - on associations between symbiotic crustaceans & gelatinous zooplankton in California here http://www.mbari.org/expeditions/Biolum ... /index.htm
