			  Collector Urchin|  |  (Pseudoboletia maculata)
 This sea urchin 
			likes to collect all kinds of rubble, like pieces of shell, bits of 
			algae and small rocks. Sea urchins are very much underappreciated 
			and have a very important job: preventing reefs to be overgrown with 
			algae. Take your time and have a closer look. Not only are there several 
			different species all around Julian Rocks, they also have a quite 
			interesting anatomy and biology.
