Long-spined Sea Urchin Diadema antillarum
Found in the western Atlantic and Caribbean. It is the most abundant and important herbivore on the coral reefs of the western Atlantic and Caribbean basin. When the population of these sea urchins is at a healthy level, they are the main grazers which prevent algae overgrowth of the reef.
