Imirya itera urubori

Uturemangingo duto cyane ibihumbi dutera urubori turasa iyo hari ikidukozeho.

Ubumara bwayo bukora iki?

When prey touches the tentacles, thousands of stinging cells (nematocysts) fire barbed stingers that inject venom. The venom contains proteins, including proteases and pore-forming toxins, which can disrupt cell membranes and tissues. The venom is effective against prey and humans, but is typically not lethal to people.1

Its stinging tentacles are its main defence, although some animals, such as leatherback turtles, are not bothered by the sting.1

Niba itera urubori

  • Sohoka mu mazi kandi ukureho imirya yayo (tentacles) yose ukoresheje uturindantoki cyangwa igitambaro.
  • Ku box jellyfish zo mu turere dushyuha: suka vinegere aho zateye urubori nibura amasegonda 30, hamagara ubutabazi kandi witegure gukora CPR (gukanda igituza no guhumekera umuntu). Ku bluebottle no ku zindi nyinshi: oza n'amazi y'inyanja, hanyuma ukoreshe amazi ashyushye kubera ububabare.

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 imwe igutereye urubori: 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

Small fish and crabs sometimes hide inside its bell, where they may feed on it.1

2

It uses light-sensing organs called ocelli to migrate from deep water up to the surface.1

3

It swims by jet propulsion, squeezing its bell to push water out, though it mostly floats.1

4

Its population may be growing because of nutrient pollution from human sources, which feeds algal blooms and the wider food chain.1

5

It is kept in many aquariums because of its bright colours and very long tentacles, and it is low-maintenance in captivity.1
