Collecting sea urchin, Pseudoboletia maculata
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.
