Halloween Urchin - Tripneustes gratilla

This is my Halloween urchin in the middle of a tug-o-war with a Xenia colony. This is a shot spine multi-color urchin. The colors happen to be the colors associated with Halloween such as orange, yellow, white and sometimes green.

My Halloween urchin would keep so many items on him that I never realy got a good clean shot of what it looked like.
