Flower urchin
The flower urchin is a sea urchin with flower-shaped claws that can sting. It lives on coral reefs, in seagrass beds and on rocky or sandy sea floors across the Indo-West Pacific. It is one of the sea urchins most likely to cause a painful and medically significant sting.1

Com reconèixer-lo
- Flower-like claws (globiferous pedicellariae) that are pinkish-white to yellowish-white, with a central purple dot and a bright white rim1
- A rigid shell (test) that is deep red and grey, with a purple zigzag pattern along each of the five ambulacral segments; rarely it is greenish or pale purple1
- Short, blunt spines, usually hidden beneath the flower-like claws1

Què fa el seu verí?
Its venom is made in glands at the base of the flower-like claws, not in the spines. The claws have sharp fang-like tips that can penetrate human skin, and when touched they snap shut and inject venom. The sting is described as extremely painful and medically significant.1

Larger individuals with bigger claws are thought to be more dangerous, because the strength of the venom is linked to claw size.1
Què fa quan té por?
