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

怎样认出它

  • 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

常被误认为： 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

毒液之力

蜇伤

毒液通过蜇刺出来。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

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

它害怕时会做什么？

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

如果它蜇人

  • 把伤口泡在热水里，水温以不烫伤为限、尽量热，然后去看医生取出刺。不要自己去挖。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。 急救基础

注意安全

  • 永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
  • 给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
  • 如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。 更多安全知识

值得了解

事实

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

谣言粉碎机

谣言： Sea urchins sting with their spines.

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