  1. yes, its the soft tube of a sabellid polychaete
  2. A bivalve in the family Galeommatidae. In some species like this one the mantle completely covers the two valves and the animal crawls or hops on its foot. Many of the species are commensals on other inverts
  3. Hi Mark -- It looks to be a nemertean worm. I can't tell for sure (images are too small) but the little white string on the left end might be either the worm's proboscis or a prey item.
  4. Yes to the first 2. The 3rd looks to me like the closed siphons of another clam.
  5. They might belong to another type of cirratulid polychaete.
  6. Hi Linda -- Thanks so much for posting this! It's quite rare to get photos of living scaleworms in this particular family. Polynoidae is a good guess as that's the largest family with hundreds of known species but there are several other families including the sea mice (Aphroditidae) where the scales are hidden under the "fur". This one belongs to family Acoetidae (= Polyodontidae in older books). You've got the head in focus which is how I can tell it's family Acoetidae - the eyes are on long stalks. Only some genera of acoetids have this feature. It's most likely to be a species of either Acoetes or Polyodontes. How large was it? A few of them get up to a meter in length. I really like that you got a bit of the tube in the second photo. They have specialized glands which produce long fibers; these are combined with mucus & sediments to build thick felt-like tubes. They rarely leave home, preferring to ambush other critters from the safety of their tubes. Cheerios, Leslie
  7. Welcome to Wetpixel Beroe, and thanks for the update. It would be nice to have a jelly pro hanging around! Cheers, Leslie
  8. Hi Frank -- It appears to be a eulimid or pyramidellid snail. Many species in both families are predators on echinoderms, sticking the proboscis through the skin in order to suck out body fluids. They're so small that they really don't hurt their prey unless there are hundreds of snails on one animal. Some species however have adapted to a parasitic way of life & live semi- or fully-permanently attached to the prey, either on the surface or internally.
  9. Fantastic video (of course I always love any & all worm vids). :-)) It is a polychaete - those lateral rows of hairs are the bristles that give the group their latin name (poly = many, chaete = bristle) & common name (bristle worms). It's just that it's moving too fast for the annulations to show. I'm pretty certain it's family Glyceridae, genus Glycera. Some species do swarm to spawn. They're called bloodworms & in south Australia, around Adelaide, there's an annual bloodworm run where fishermen go out at night to catch as many as possible. They preserve the worms for use as bait throughout the year. http://www.strikehook.com/forum/5-general-fishing/162556-2011-bloodworm-run?start=15
  10. Crabs will eat anything. I've seen a video of one dropping his own claw, picking it up, and eating the meat out of it. Now a general question to anyone who's ever seen one of these blue porcelain crabs. I'm curious to know if it's always on pink or red barrel sponges? Is it ever on anything else? (and having a dive guide place it on black sand for contrast doesn't count!)
  11. I passed your photo along to Gordon Hendler, the museum's curator of echinoderms & an ophiuroid specialist. He thinks the brittle may be Ophiothrix nereidina which comes in a variety of colors.
  12. It's a still undescribed species of porcelain crab in the genus Aliaporcellana. Judging by the amount of photos I've seen it's not rare and it's normally found on that pink sponge. I'm more interested in the brittle star. Do you have any pictures showing the central disk or a high-res image of the arms?
  13. I forwarded your image to Lindsey Groves, our museum's collection manager of molluscs. Here's his response: "Definitely not an Opalia (FYI, O. chacei has been synonymized with O. borealis). It is most likelyEpitonium montereyensis, which Jim called E. indianorum in the Light’s Manual revision in 2007 (pl. 367E). Epitonium tinctum would be a best second best guess. The tiny specimen to the left of the large epitoniid is too small to id from this image. Hope this helps." Jim is Jim McLean, the museum's curator emeritus of molluscs
