I noticed a pile of shells in the front of my four month old tank. I started with live rock. In the middle of the pile I found this urchin. It doesn't look like a black rock boring or collector tuxedo urchin. Any ideas?

Probably a type of urchin commonly called a "purple urchin" or purple pincushion/short-spine urchin.
Where did the live rock originate? The purple urchins are quite invasive in some areas.

Just hopped on at the right time for ID and found some I've seen before (I enjoy researching ID).
