Niba amahwa yayo akujombye

  • Shyira igikomere mu mazi ashyushye, ashyushye uko umuntu abyihanganira atiriwe ashya, kandi ushake ubufasha bwa muganga kugira ngo amahwa avanwemo. Ntukayacukure ubwawe.

Buri gihe banza uhamagare nimero y'ubutabazi (112, 000, 911). Izi ni inama rusange z'ubutabazi bw'ibanze, si inama za muganga. Ibanze by'ubutabazi bw'ibanze

Irinde akaga

  • Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
  • Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
  • Niba amahwa yayo akujombye: tuza, ntunyeganyege, hamagara nimero y'ubutabazi (112, 000, 911) cyangwa ujye ku bitaro vuba. Ibuka uko yasaga, ifoto irafasha.

Ntigushakisha ngo ikugirire nabi. Ikoresha ubumara bwayo kugira ngo ifate ibyo kurya cyangwa yirinde, kandi ikunda cyane kwihisha. Ibindi ku kwirinda

Ibintu by'ukuri

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
