The egg-yolk jellyfish is a very large jellyfish with a bright yellow centre that looks like a fried egg. It lives in cool seas across most of the world's oceans and is most common in the Northern Pacific. It is special because it can grow very large, and it is one of the few jellyfish that can survive in low-oxygen water.1

Domov

It lives in cool open seas and drifts with the current. Its polyp stage attaches to rocks and piers, so people may come across the animal near piers and rocky shores.1

Dolžina

Kaj je?

It mainly eats gelatinous zooplankton and smaller jellyfish, along with fish and fish larvae. It catches prey with its tentacles, covers the food in mucus, and brings it to its mouth with its oral lobes.1

Kako jo prepoznaš

A yellow centre that looks like a broken egg yolk, surrounded by opaque white tissue1
A large bell, sometimes close to 60 cm across1
16 clusters of tentacles, each with up to a few dozen tentacles, and each tentacle up to 6 m long1
Broad, curtain-like oral arms1
Mostly drifts with the current, with only limited movement1

Pogosto zamenjujejo z: The lion's mane jellyfish (Cyanea capillata) is sometimes confused with this species. The smaller Cotylorhiza tuberculata, which is found mainly in warmer water, especially in the Mediterranean Sea, is also called a fried egg jellyfish.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?

Its tentacles contain nematocysts, stinging cells that help it catch prey. Its sting is weak, which allows some small animals to ride on its bell and steal food from its arms and tentacles.1

Kaj naredi, ko se prestraši?

Its tentacles contain nematocysts, which also help protect it from predators.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

vredno vedeti

Dejstva

Its tentacles can reach up to 6 m long, which is far longer than its bell.1

It has no gills, lungs or circulatory system. It takes in oxygen through its thin body surface instead.1

The giant deep-sea octopus Haliphron atlanticus clings to this jellyfish and eats its oral arms and stomach.1

It can survive in low-oxygen water for several hours at a time, and it sometimes dives into these zones during the day to avoid competition.1

Small crabs and an amphipod called Hyperia medusarum can live on its bell, and some feed on the parasites that infest the jellyfish.1
