How to remove a rock-boring urchin from its burrow/hole?

Hey Guys,

I have what I think is a rock boring urchin that came as a hitchhiker on a piece of liverock that is currently in my sump. I want to remove the piece of rock as itís home to some unwanted hitchhikers I canít get rid of.

I donít necessarily want to get rid of the urchin. Does anyone have any idea on how to remove the urchin from its hole/burrow without harming it?
