Urchin Pictures

If you look closely at this pincushion urchin (Tripneustes gratilla) that I just received from LiveAquaria (http://www.liveaquaria.com/product/prod_display.cfm?c=497+530+594&pcatid=594), you can see a number of black spots that it is holding on to. What are these? A number of them were floating around in the shipping water as well.

Pretty sure that's just the tips of its tube feet.

There were quite a few of them floating around in the water, I hope they are not the tips of the tube feet !
