Okay, so we paused by the tank before going to bed and saw the urchin on a rock where we could really look at it. Then the kids started laughing hysterically. The orange spot in the middle (I'm thinking it's an anal organ, but the kids thought it was an eye) was pulsing in and out of the body of the urchin. VERY bizzare! When I told them I thought that was the anal organ, they were totally grossed out. They were joking about constipation, and doing sound effects for it!
Is that normal behavior for an urchin? My son wants to know if he might have swallowed a bristle worm...
