  1. Brian & I corresponded about this. I thought - maybe - it might be a megalopa since there appears to be a semi-extended abdomen, then sent it to our crustacea curator, Jody Martin, for his opinion. With the lack of detail Jody was unwilling to even go that far with an id. So if anyone sees a tiny crustacean with bright yellow eyes please take a photo! Maybe we can figure it out.

  2. It could be a coincidence since they're both feeding on the entoprocts and they do tend to be pretty oblivious to others or obstacles when feeding and travelling. I've seen photos of them crawling over scorpion fish, frogfish, wobbies, etc. On the other hand, it could be a prelude/aftermath to mating. As Greedo said, they mate right side to right side. Nudis can be sexually reproductive at small sizes so mating is a possibility.

  3. Hi Brian --


    The red one is easy - Liomera cinctimana. It occurs on both sides of the Pacific & I remember it because I photographed one in Panama.


    The other, well, I wish you had gotten a photo of it from the top. It appears to be a xanthid or in a related family & reminds me of the teddy bear crab Polydectus cupulifera but doesn't have near enough "hair".

  4. I am getting so forgetful you might as well just shoot me & get it over with. Art replied that it was probably a parasitic dajid isopod so I searched around and found this - http://sg.homeunix.com/jovin/Gorontalo-Nov...nemone_shrimp_6 It's the same species of isopod & shrimp. If you click for an enlargement you can actually see the legs of the dajid. The someone from scubaboard who identified it has the initials LH and works for a museum in Los Angeles..... DOH!

  5. Color varies. So does shape as that can depend on whether it's on the seafloor or covering a rock or waving in the current. Also, the shape changes when the cyanobacteria produce air bubbles that lift up the algae. On the other hand, you saw it for real and I'm just guessing. :-)

  6. Hi Bent -- Thanks so much for posting these. They're polychaetes worms in the family Onuphidae. Clear tubes are associated with the genus Hyalinoecia, some species of which have been reported from Indonesia. I can't be positive without examining some under a microscope. Most polychaetes can easily turn around in their tubes or crawl backwards.


    Got any other worms? :-)


    Cheers, Leslie

  7. "Species 1", "species A", etc., are what we call provisional species names. Usually they're just designations given by the guide book's author for things they can't get names for. In that case you'll find the same species listed under different designations in different books.


    If the provisional name is followed by a researcher's name such as "Alpheus sp. 12 Anker" or the book is by a specialist like Terry Gosliner then it means that a specialist recognizes the species as probably unique and undescribed.

  8. Hi Marli -- Art's on his way to Brazil I think. I'd go with Vir euphyllius. The white patches are internal organs which vary in size so they're not a useful character. It would be unusually pale for a euphyllius but intensity of color varies too and the host is certainly right for a Vir.
