The Diadema sea urchin, with its long, slender spines, is commonly known as the "devil sea urchin" and is a frequent resident of rocky reef coastlines. Its spherical anal papillae are one of its most distinctive features. These urchins often erode pits and holes into the reef surface, and after dark they roam the rocks grazing on algae. Although their formidable spines help defend against many predators, for a variety of small creatures the Diadema sea urchin is actually a safe sanctuary — off-limits to outsiders — and some organisms even spend their entire lives making a home among its spines! Let's get to know them through the Marine Habitat & Life Micro-Education Series!
