The green sea urchin - Psammechinus miliaris

This spiny little fellow can be found at low tide hiding under rocks around the coast of Cornwall. They survive by grazing on the various other things living on the rocks including barnacles, tube worms and algae.

It is said that the green sea urchin's gonads are considered a delicacy in some countries!
