  1. I'm not sure of the species but it's a pelagic snail. They spend their entire lives swimming which is made possible by the development of a swimming fin and reduction in the size & weight of the shell. If this had been found off California I would call it Carinaria cristata. You can try to figure out the species using the character table on this page:

  2. Hi Marli -- Send a PM to the Poppes via member cookmedoc. I'm sure they can help. They're mollusc experts and I bet anything they have a copy of the magnificent new book on ovulids. Unfortunately the cost is magnificent too so I have to save up to buy a copy.


  3. Hi everyone --

     

    The meeting tonight had to be cancelled. For safety reasons the museum will be locked down today. The Lakers parade ends at the adjacent Coliseum. Even though the rally officially ends at 1 PM many of the surrounding streets & freeway ramps won't be open until 4 pm. I checked with Security and they will not re-open it this evening just for our meeting.

    Sorry, Leslie


  4. The common name is squat lobster. They're in the family Galatheidae which are anomurans along with hermit crabs & porcelain crabs. The easiest way to distinguish anomurans & true crabs (brachyurans) is that anomurans have 4 pairs of legs while true crabs which are in Brachyura have 5 pairs of legs. There are hundreds of species and I've heard estimates that there are even more undescribed species than named ones.


  5. Lindsey forwarded the image to Dirk Fehse, one of the authors of the brand new book "The Living Ovulidae" by Felix Lorenz & Dirk Fehse. It's an amazing authorative book with tons of images of both shells & live animals. The unfortunate part is that the price is 120 euros plus shipping but it's definitely worth it for ovulid fans. Anyway, Dirk thinks it's probably a juvenile Cyphoma sedlaki which was described from the Florida Keys.


  6. I had the same doubt about the two. He's positive on the one you had listed as juvenile flamingo's tongue and was pretty sure on the other. Lindsey offered to forward the one with thin red circles to an ovulid expert so I'll ask him to do that.


  7. More common but still undescribed. It's listed as Saron sp 2 in Debelius' crustacea book. I checked & couldn't find any recent papers on it. There are several undescribed species in the genus. Some of them have been shoe-horned into S. marmoratus or S. neglectus because there's some similarity in the coloration. The genus is in great need of revision but since some of these species have only been photographed, never collected, it will be hard to do.


  8. Anisa Abid of NG Television called me to see if I had any footage of bobbitt worms or other ambush predators. Me? Ha! Contact Anisa directly if you have footage you think might be suitable. Her email is aabid@ngs.org

     

    "As I mentioned on the phone, I'm looking for footage of the following marine species using their ambush predator tactics on prey, preferably in high speed and HD. If anyone from your forum might happen to have this I would greatly appreciate if they could contact me as soon as possible (we're on a tight deadline). This would be for inclusion in a program by National Geographic Television on ambush predators.

     

    bobbit worm

    northern stargazer

    mantis shrimp

    stonefish

    anglerfish

     

    Other footage of non-marine species are also being sought after:

    bolas spider

    crab spider

    goliath spider

    fireflies

    new zealand glow worm

    dragonfly larvae

    horned lizard

    chameleons (slinging their tongue)

    salamanders

    toads

    praying mantis

     

    Many thanks!

  9. Hi Phil - well, you've hit the jackpot. That's a very rarely seen Saron known only from Indonesia. It's listed as Saron sp 3 in Debelius' Crustacea Guide of the World. At the time he wrote the book it had yet to be collected or described. Good eye and good photo!


  10. That would be Periclimenes holthuisi unless some clever taxonomist has come along & split it up into different species. It has an interesting life style. During the day it hangs out among anemones where it feeds by clipping off pieces of the tentacles. At night when the anemone closes up the shrimp moves down to the column or off the anemone completely.
