  1. Definitely different species & species, maybe family too. It reminds me more of a Periclimenes than a Hippolyte commensalis. I'll have to ask the shrimp patrol.
  2. The first is a variant of Phyllidia occellata as you suspected while the second is Reticulidia halgerda -- http://www.seaslugforum.net/find/phylocel http://www.seaslugforum.net/retihalg.htm
  3. My god that's huge! It's a pelagic tunicate. The group name for these is Larvacea because they retain the tail & pelagic life style of typical tunicate larvae. Normally Oikopleura forms a mucus house which acts as a giant filter to collect food particles. The houses don't last very long so the Oikopleura constantly makes new ones while the discarded houses sink down to the bottom. See how there's a cloud of particles & mucus strings that travel at the same speed as the animal in your video? That's the transparent house. The typical larvacean (also called appendicularian) is tiny, just a few millimeters long and transparent. I've never seen one like this. http://www.microscopy-uk.org.uk/mag/indexm...jan01/oiko.html http://www.tafi.org.au/zooplankton/imageke...aria/index.html This image from the Philippines by the Poppes appears to be the same species. They called it Oikopleura and I'd love to know what reference they used for the name. http://www.poppe-images.com/?t=17&photoid=942672
  4. Hi Marli -- I checked with some reefer friends and they agree. Good sleuth work!
  5. I really hate guessing genus in flatworms! So much of the characters are internal that it's really a shot in the dark. I mean, Pseudoceros & Pseudobiceros are distinguished by the presence of a single penis or two penises so unless you get a photo of an animal penis-fencing it's kinda hard to tell.....
  6. Cute little wormie. Looks like it can't decide if it wants to be camouflaged (the middle section) or advertise its toxicity (margin). But I can't find it either......
  7. Gooseneck barnacles to be a bit more specific. Check out Scapellum and Lepas for similar looking species.

    Worm

    You know me so well, Brian ;-) But I don't know what it is :-(
  9. Looks like Jon must be away. that man gets more invites for field work than anyone I know. Hopefully he'll take a look once he's back from whatever fabulous place he's in now.
  10. Thanks for posting them. Bootlace worms, definitely, and out of my comfort zone both phyletically & geographically. This is a job for Nemertinator, the defender of truth, justice, and the nemertean way of life. I'll ask him to pop by. Ta--
  11. First impression is that it's an oddly colored Bohadschia argus but with cukes first impressions are often wrong. Why don't you contact the IP holothurioid expert Gustav Paulay? \http://www.flmnh.ufl.edu/malacology/paulay.htm
  12. Yup, sea fan or gorgonian. James & Acropora are the two best tropical cnidarian people around here - send them a PM if they don't show up soon.
  13. [quote name='waso' date='Sep 17 2010, 03:01 PM' post='261410' Where are the experts??? Exactly what I was wondering. C'mon people, let's have some help here! Don't expect a worm girl to do fish ids, you know I can barely tell the difference between a Hippocampus and a Mola.... :- D
  14. Hi Alex - It looks to me like Hamodactylus noumaea. Common name is gorgonian shrimp, with the color always matching the host. There's another species, boschmai, but that has a regular pattern of white dots on the back and is a bit more transparent.
  15. :) And what a lovely worm it is. Family Eunicidae, genus Eunice. The color pattern - red with a white band across an anterior segment - is typical of many species in the genus.
  16. Everything? That sucks! How/why did it happen?
  17. Hi Jim -- Family Marginellidae, probably genus Volvarina. There are a lot of species in the this group that look a lot alike. Classification in molluscs is based on shell characters and there's still not as much known about what the live animals look like. Here's a similar species photographed by Art Anker - http://www.flickr.com/photos/artour_a/374980420/ How's the camera? Did you get a replacement?
  18. My guess is some species of stick crab like Chalaroachaeus curvipes - http://wetpixel.com/forums/index.php?showtopic=37345 http://wikitivity.jp/scuba-diving/modules/...%82%A6%E3%82%B9 The two legs with claws by the mouth are short & used for manipulation rather than walking. In Steve's pic the two legs are sort of dead center. Liquidguru's got an outstanding video on his http://divekbr.com/blog/?cat=4 which shows a related crab - the skinny sponge crab (Oncinopus or Achaeus depending on which reference you check) right after molting. It's using the two short arms to pick pieces of sponge away from the discarded carapace & transfer them to it's new carapace. This is typical behavior for decorator crabs & other crustaceans. Even the big hermits that carry anemones on their shells will move the anemones from an old shell to a new one.
  19. Thanks Jon. It's always great when you show up to put names on things.
  20. You lucky stiff. I haven't been out of the museum in nearly two long boring years....... Glad to have you back! )
  21. Some of the pics I see that are labelled Baseodiscus quinquelineatus have 5 black dorsal lines on a white body. Sometimes the 2 outermost are close to the lateral edge but they're not ventral. What are they?
  22. Great video for fish & invert lovers. The spotted pom-pom crabs & the octopus are particularly nice--- Merged with topic : Adam
  23. Here's the current list of species in Ancylomenes. Some of the most common species have been switched including the Caribbean pedersoni.
