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

Hoe om dit te herken

  • 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

Word dikwels verwar met: 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

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

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

Wat doen dit as dit bang is?

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

As dit steek

  • Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand, en kry mediese hulp om die stekels te verwyder. Moenie self daarna grawe nie.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

  • Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
  • Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
  • As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

1

Unlike most venomous sea urchins, it does not sting through its spines. Its venom is delivered through the claws.1

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

Mite-breker

Mite: Sea urchins sting with their spines.

Waarheid: Flower urchins do not deliver venom through their spines. Their venom comes from the flower-like claws, which snap shut and inject it.1
