Worms! I finally got the video together and uploaded.
I haven't been able to id these worms; the closest I can find are the three-section tubeworms, but they don't quite match. I'd appreciate any help!
(As before, the sound only works for me after I've switched the settings to 480p. I can't figure out why. And get rid of the ad asap; it's hiding a couple of captions. Viewing the worm full-screen gives you a better look at the features of the head and tentacles.)

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.
Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!

Yikes! Strange little creature! But efficient too!
ReplyDeleteI can't find the words to tell you how much I enjoyed this video. What a wonderful little creature! Your captions and music were perfect.
ReplyDeleteThank you. You manage to teach me and also abate my longing for the Ocean and its creatures somewhat!
What a wonderful, informative, and entertaining video! Thank you for the post.
ReplyDeleteThere is so much life around us that we are not aware of - thanks so much for sharing these little creatures with us. I'm amazed at how those tentacles work as conveyor belts, bringing materials in & out of the tube. Pretty cool!
ReplyDeleteCool! i didn't know about any of that. Enjoyed your video very much.
ReplyDeleteWhat an amazing video. You really get the details. - Margy
ReplyDeleteI had no idea they use their tentacles like that. I assumed they'd grab something, and retract it into their mouth, but your video shows otherwise. I wonder if that "conveyor belt" motion is akin to how a snail moves, or perhaps using micro-feet (cilia) to move food in.
ReplyDeleteBTW, what is the status of your crab population? Did any of the young survive?
Thanks, all!
ReplyDeleteTim, I wonder about that conveyor belt action. I read somewhere that the food moves along a groove in the tentacles, but that's all I could find. Except that another website said that the tentacles were only used to remove food, and from what I saw and videoed, food is also being captured and brought down to the tube mouth.
About the crabs; there are two very small crabs in the tank that I didn't bring home, as far as I know. And a couple of days ago, I was watching, and saw some sand grains moving around, so I used the hand lens. And there was a crab there, barely bigger than the grains of sand.
Whether it's one of Ma Crabs or not, I can't tell. I'm not sure of the timing, and I have brought home fresh salt water for them. But it could be.
