Urchin stole a polyp

So I have a purple urchin don't know the species kinda looks like maybe tuxedo came on some rock while back and started as a tiny speck with a piece of shell on its back. Anybow it is always picking things up as camo like it had a hermit crab riding along until crab pulled itself off but always has empty shells and rubble on it. Well found it today with a polyp off of my snake polyp colony. I am assuming the polyp is still alive but don't know guess I'll have to wait till late tonight to see if it opens to feed. Sorry for the pic used my iPhone.

Yep that's what urchins do.
If you have frags in your tank and they are not sucured good with some kind of super coral glue the urchin if it comes along will take it for a ride.
