The compass jellyfish is a common jellyfish that lives in cool coastal seas of the northeast Atlantic, including the North Sea and the Mediterranean. Its bell has a pattern that looks like the face of a compass, which gives it its name. Its tentacles carry stinging cells, so it is best left alone.1

Uko wayimenya

  • Adults have a bell 15 to 25 cm across, usually yellowish white with some brown.1
  • The bell has 16 brown, elongated V-shaped markings around a central brown spot.1
  • It has 24 tentacles arranged in eight groups of three.1
  • It has four oral arms that are noticeably longer than the tentacles and look folded and frilly.1
  • Juveniles lack the compass pattern. They look white and polka-dotted, with a reddish fringe on the bell edge.1

Ikunze kwitiranywa na: Records of this species from the southeastern Atlantic, including South Africa, were caused by confusion with close relatives: C. africana, C. fulgida and an undescribed species tentatively called "C. agulhensis".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

Males release sperm from their mouths into the water, and females can fertilise sperm from several males.1

Adults often carry a parasite called Hyperia medusarum, which settles inside the body, especially the gonads.1

3

Compass jellyfish have very few predators. Leatherback sea turtles and ocean sunfish are known to eat them.1

4

Warmer winters allow longer release periods for young, and the species is predicted to move further north as the seas warm.1

Usenya ibinyoma

Ikinyoma: Compass jellyfish live in the southeastern Atlantic, including South Africa.
