Long-spined black sea urchin

Description:

The Long-spined Sea Urchin (Diadema setosum) is a regular sea urchin commonly seen on our reefs. It has long, needle-like spines which break easily upon contact. These spines are hollow, containing a mild venom, and broken spines are very difficult to remove when they penetrate the victim's skin of the victim, causing pain and discomfort. This sea urchin has an orange anal cone and five equally spaced white spots on the upper side.
