The radiant sea urchin is a large, colourful sea urchin with long, spiky spines. It lives in warm, shallow seas across the Indo-Pacific, from the African coast to Hawaii and Australia. Its spines are venomous, so it is one to admire from a distance.1

It is not deadly to humans, but its spines can cause painful wounds. Because it is large and brightly coloured, divers can usually see it, so injuries from stepping on one are fairly rare. On the 'Kings of Pain' pain index it scores 12 out of 30.1

It is sensitive to light and can angle its spines towards an approaching threat.1
