Sea urchins are spiny, globe-shaped creatures commonly found on rocky seabeds and coral reefs in Cyprus. With their hard shells and radiating spines, they play an important role in the marine ecosystem by grazing on algae and maintaining the balance of underwater habitats. While their sharp spines serve as a natural defense, sea urchins are fascinating to observe and add texture to the underwater landscape. Divers should admire them carefully to avoid accidental contact!
