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

Sihlala
Coastal waters of the northeast Atlantic, including the Celtic, Irish, North and Mediterranean Seas1
uLwandlekazi lweAtlantiki, uLwandle lweMeditera, uLwandle lwaseMntla (North Sea)
Ekhaya
It lives in shallow coastal water and moves up and down the water column, mostly near the surface and down to just above the seabed. It is rarely found deeper than 30 m.1
Ubude
15 cm ukuya ku-25 cm (5,9 in ukuya ku-9,8 in)1
Esona santya siphezulu
malunga ne-0,7 km/h (0,44 mph)
Ukuqubha, uqikelelo nje
Sitya ntoni?
It eats other marine invertebrates and plankton, including dinoflagellates, copepods, crustacean eggs, larval fish and chaetognaths. It stuns and catches prey with stinging cells on its tentacles, then its oral arms move the prey into its mouth.1

Indlela yokusiqaphela

  • 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

Sidla ngokubhidaniswa no: 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

Amandla etyhefu yokuluma nokuhlaba

Ii-tentacle ezihlabayo

Amawaka eeseli ezincinci ezihlabayo ziyadubula xa kukho into ezichukumisayo.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

Each tentacle has stinging cells used to capture prey and to defend against predators. Jellyfish stings are painful and can be deadly to humans.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

Senza ntoni xa soyika?

Stinging cells on its tentacles are used to defend it from predators.1

Ukuba siyahlaba

  • Phuma emanzini kwaye ususe naziphi na ii-tentacle (ngeiglavu okanye ngelaphu).
  • Kwiijelifishi zebhokisi (box jellyfish) zasetropiki: thela iviniga kwiindawo ezihlatyiweyo ubuncinane imizuzwana engama-30, biza uncedo kwaye ulungele ukwenza i-CPR. Kwii-bluebottle nakwezinye ezininzi: hlambulula ngamanzi olwandle, emva koko usebenzise amanzi ashushu ngenxa yeentlungu.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

  • Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
  • Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
  • Ukuba siyakuhlaba: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

1

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

2

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

Umqhekezi weentsomi

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

Inyaniso: Earlier records from there were due to confusion with close relatives. The species lives in the northeast Atlantic.1
