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

Leef in

Cool waters of most of the world's oceans, most common in the Northern Pacific1

Stille Oseaan

Tuis

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

Lengte

59 cm (1,9 ft)1

Topspoed

omtrent 1,3 km/h (0,81 mph)

Swem, rowwe skatting

Wat eet dit?

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

Hoe om dit te herken

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

Word dikwels verwar met: 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

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Its sting is weak.1

Wat doen dit as dit bang is?

Its tentacles contain nematocysts, which also help protect it from predators.1

As dit steek

Klim uit die water en pluk enige tentakels af (met handskoene of 'n lap).
Vir tropiese kubuskwalle: gooi vir minstens 30 sekondes asyn oor die steke, roep hulp en wees gereed om KPR te doen. Vir bloublasies en die meeste ander: spoel af met seewater, dan warm water vir die pyn.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Net wiskunde in jou blaaier. Niks word gestoor of enige plek heen gestuur nie.

Hoe vinnig is dit?

'n Tuinslak omtrent 0,05 km/h (0,03 mph)

Egg-yolk jellyfish omtrent 1,3 km/h (0,81 mph)

'n Mens wat swem omtrent 3 km/h (1,9 mph)

die moeite werd om te weet

Feite

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
