Description
To me, one of the most interesting animals in the ocean has always been sea urchins. When I was diving I loved to watch them intently, watching their spines bristle and move slowly and I would always find their skeletons all over the bottom. The shells or skeletons are actually called TESTS. A test is made up of magnesium calcite plates fused together beneath the skin, and a bare test is quite intricate in nature and very beautiful. They can be several different colors, but most of what I've witnessed have been black, green, or red or purplish red. These shells are just one more marvels of nature.
