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

Como recoñecelo

  • 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

Adoita confundirse con: 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

Poder da pezoña

Pica

A pezoña sae por un ferrete.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: Moi perigosoPode matar a unha persoa que non reciba tratamento.

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

Que fai cando ten medo?

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

Se pica

  • Mete a ferida en auga quente, tan quente como a persoa poida aguantar sen queimarse, e busca axuda médica para quitar as espiñas. Non as intentes sacar ti escarvando.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

2

A zebra crab, Zebrida adamsii, often lives attached to its shell. The crab is thought to be immune to its venom.1

3

Its flower-like claws are the source of its common name and are its most striking feature.1

4

Tiny shrimp, Athanas areteformis, sometimes live among its spines.1

5

In the seashell trade, its empty shells are called "mushroom urchins" because they look like mushroom caps.1

Desmontamitos

Mito: Sea urchins sting with their spines.
