NEEDLE-SPINED URCHIN (Diadema savignyi)
Biodiversity > Marine Life > Echinoderm > Sea urchins

Diadema savignyi

The Needle-spined Urchin is distinguished by its 10cm long, brittle, black spines and five bright blue V spots on its upper surface. These urchins are very alert and quickly sense the presence of an intruder. They immediately start to wave their menacing armory, and their spines are capable of injecting poison, which will cause pain for several hours. They are more common in deeper water -for example, the lagoon area at North Bay.
