Made some interesting observations today of the feather star! But alas, a camera can (almost) never be as astute as the human eye. I've tried to capture the moment on film, but you need to look REALLY CLOSELY.
Now, if you remember the picture of the whitish, really fine hairs on the feather star's arm, a couple of posts down? Look closely at those hairs (not the huge, red feather) in this video. I just fed the tank with 0.5ml of frozen oyster eggs (roughly 1 - 1.5 million eggs, each 30-50 microns in size). The whitish, fine hairs started making random flapping movements! I can't see the oyster eggs, obviously, so I can't see how the feather star actually captures the food, but its a start.
** The embedded video is really tiny, so you won't be able to see anything. To see a blown-up version, click on the video itself - you'll be taken to the page itself on Youtube's domain. At the bottom right of the video there's a grey panel with several icons, click on the very last one - that'll blow the screen up real huge, and even then, you might need to observe the video a few times to catch it happening. A little tip: look at the left side of the "feather", near the middle. The whitish hairs form this pale, translucent "curtain", but once in a while you'll notice flicking movements and the appearance of transparent windows in the "curtain" - that's the hairs flicking downwards, so you get to see the background clearly. **
