The calcareous remains (known as the "test") of one of about 50 Black Sea Urchins (Centrostephanus rodgersii) I found washed up high onto the rocky shoreline of a beach near Ukumehame. This one had most of its spines scrubbed off in the surf. Considering how delicate the test is without living tissue to hold it together, it's amazing that it's still intact.
