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

Anaishi
Western Atlantic, Caribbean Sea, Gulf of Mexico, northern and eastern South America (as far south as Brazil), Canary Islands and the Indian Ocean1
Bahari ya Atlantiki, Bahari ya Karibi, Ghuba ya Meksiko
Nyumbani
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

Nguvu ya sumu

Miiba yenye sumu

Miiba mikali hubeba sumu. Kumkanyaga au kumshika kunauma.

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

Miiba yake ikikuchoma

  • Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua, na utafute msaada wa kitabibu kuondoa miiba. Usiichokonoe mwenyewe.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Miiba yake ikikuchoma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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
