Long-spined Sea Urchin
Diadema setosum

Adults inhabit tropical coral reefs, lagoons, and rocky coastal shallows, sheltering in crevices by day and foraging at night. They scrape algae and organic material from hard surfaces with a complex tooth apparatus. Their exceptionally long, venomous spines provide strong protection, while bright blue lines can be visible on the body.
