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

  • 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
  • A body diameter of about 15 to 20 cm1

Savens confundì cun: Other Toxopneustes urchins look similar. Toxopneustes roseus has a uniform pink, brown or purple test and lives only in the eastern Pacific. Toxopneustes elegans, found only around Japan, has a dark stripe just below the tips of its spines. Toxopneustes maculatus is very rare, known from Réunion, Christmas Island and Palmyra Atoll, and has bright violet on its underside and a violet band around its middle.1

Tge fa ses tissi?

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

It is considered highly dangerous to people. Its stings are extremely painful and medically significant. Larger individuals with bigger claws are thought to be more dangerous, because the strength of the venom is linked to claw size.1

Tge fa el, cura ch'el ha tema?

When touched or brushed against, its flower-like claws snap shut and inject venom. The claws can break off and stay attached to the skin, continuing to inject venom for several hours.1
