I finally got a decent pic of my tiny brittlestar with black-and-white striped legs. Each leg is about 3/4 inch long - I believe he has 5 of them. He lives in a hole in the liverock and is normally very hard to see (I used a flash and greatly enlarged the photo).

He is a filter feeder and will catches small fragments of flakes. Actually, I now squirt the tiny flakes suspended in salt water by using a turkey baster - that way I make sure he gets food every day.

That's a nice little brittle star. I've got little ones, too, but they're always gray or white without the snazzy stripes.

I have little white ones too, but they come out and crawl around.
Marvin (that's what I've named him) is special.

It was Colin who advised me to take a large magnifying glass and examine my live rock to discover all the small interesting things living there. If you haven't tried this, you should.

A brittle star (sometimes called a serpent star) is related to sea stars and sea urchins (and sea cucumbers and crinoids). They have five very flexible arms connected to a central disk.
