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

Kaj je?
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

Kako jo prepoznaš

  • 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

Pogosto zamenjujejo z: 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

Moč strupa

Ožigalne lovke

Na tisoče drobnih ožigalnih celic se sproži, ko se jih kaj dotakne.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Če piči

  • Pojdi iz vode in odstrani lovke (z rokavicami ali s krpo).
  • Pri tropskih kockastih meduzah: pike vsaj 30 sekund polivaj s kisom, pokliči pomoč in bodi pripravljen na oživljanje (TPO). Pri portugalskih ladjicah in večini drugih: izperi z morsko vodo, nato pa za bolečino uporabi vročo vodo.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

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

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