Thanks, but I wasn't referring to the 'holding' legs... if you look at the pic, just to the left of the big arm which is curling away to the left, you can see two smaller arms, much smaller than the rest, complete with the feeding 'feathers'.I agree with what's been said above regarding crinoids losing limbs or tips of limbs due to stress of import and shipping or acclimation. But, what you're seeing under it are actually the "legs" which are the arms it uses to hang onto rocks, there should be 5 of them. Notice how they're curled onto the rock it's on. Unfortunately it isn't growing new limbs (at least not yet) it takes much longer than a week or so to regenerate. Also the arms would grow right alongside the others and would look just like them but smaller. Sorry to be that guy, but that's the answer.
