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.)
