Long-Spined Urchin (Diadema antillarum) – Blue Heron Bridge, Riviera Beach, FL
Looking beyond the spiny defense of an urchin takes a steady hand. Moving in tight to image the ‘body’ of this urchin was tough because of the long length of its spines (~15cm). Once in position, I could see the periproctal cone (sphere) and freckled ridges – a sight I have rarely leaned in far enough to enjoy. Click the image to zoom and ‘lean in’ for yourself.
