[BlueTrend Mini Classroom] Diadema Urchin Edition | Marine Habitat & Species Micro-Education Materials Part 6 ft. Ocean Conservation Administration & Keelung City Government

(Don't forget to turn on the subtitle function!)

The diadema sea urchin, with its long, slender spines, is commonly known as the "devil urchin" and is a frequent resident of rocky reef coastlines. It has a distinctive spherical anal papilla that serves as one of its most recognizable features. These urchins often bore pits and holes into rocky reefs, and after nightfall they roam the reef to graze on algae. Although the diadema urchin's spines allow it to fend off many natural predators, for many small creatures the urchin actually becomes a safe haven to stay away from — and some organisms even make the urchin's spines their permanent home! Let's get to know them through the Marine Habitat & Species Micro-Education Materials!
