Copula sivickisi is a tiny box jellyfish, about 1 cm across, that lives in shallow warm seas. It is the only species in its genus and is active only at night. It is unusual among box jellyfish because it has a mating ritual and fertilises its eggs inside the body.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

It has twenty-four eyes, grouped on four stalked structures called rhopalia on the rim of the bell.1

2

Unlike most box jellyfish, it has an elaborate mating ritual. A male grabs a female by one tentacle and pulls her around while they entwine.1

3

A female has been seen mating with several males, up to eight times in a two-hour period.1

4

It is attracted to light, and it chooses a spot on the seabed soon after dawn, spending a few minutes selecting a good location before settling there.1

5

Its average maximum swimming speed is 4.9 cm per second, which is faster than the currents near the surface of the shallow waters where it lives.1

6

The male passes a red bundle of sperm (a spermatophore) to one of the female's tentacles, which pushes it into her manubrium, the tube hanging from the underside of the bell.1

Eggs are fertilised inside the female's bell. About two or three days later she releases a mucous strand of embryos into the sea, and these develop into polyps.1
