The long-spined sea urchin is a spiny, black sea creature that lives on coral reefs. It is one of the most important grazers on Caribbean and western Atlantic reefs, because it eats the algae that could otherwise smother the coral.1

It usually lives on coral reefs at depths of 1 to 10 metres. It often hides in a crevice, so that only its spines can be seen. Those that cannot find a crevice live in more exposed places.1

它对人有多危险?

对人的危险: 很疼可能真的很疼,但几乎从不严重。

如果它的刺扎到你

  • 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。
  • 如果它的刺扎到你: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

事实

1

Some individuals have spines up to 30 cm long, while most sea urchins have spines of only 1 to 3 cm.1

2

In 1983, more than 97% of this sea urchin died across the Caribbean in a mass die-off, and the reefs became overgrown with algae.1

3

When males and females are ready to spawn, they release a fluid that alerts other urchins to release their eggs and sperm too.1

4

It is the most abundant and important herbivore on the coral reefs of the western Atlantic and Caribbean.1

5

Dedicated nurseries that grow these urchins to help restore reefs exist in Jamaica and Puerto Rico.1
