Here a crinoid is hanging down. It's not its usual stance, but you can see the little toothpick size legs or feet (in the upper left-hand corner of the image) where it is attached to a piece of hard coral. See Crinoid on Hard Coral for more description of this animal and Yellow Crinoid for a more typical shape. I especially like the repetition of design seen in Orange Crinoid Curl.
