Radiant sea urchin
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

Dintlha
A crab called Dorippe frascone carries the urchin on its back.1
Several shrimps, crabs and small fish live among its spines for shelter.1
Its scientific name refers to a star-shaped pattern around its anus, not to the animal's shape as a whole.1
Its bright colours and size make it a favourite subject for underwater photographers and some expert fish-keepers.1
Its young larvae drift in the ocean as plankton before they settle on the seabed.1
