The clinging jellyfish is a small jellyfish, with a bell only 1 to 3 cm across. It lives in shallow coastal waters across much of the Northern Hemisphere. Its sting can be strong in some areas, so it is worth knowing what it looks like.1

Leef in

Shallow coastal waters of the north Pacific, including Japan and Russia; also Europe, the Atlantic coast of the United States and parts of the Mediterranean1

Stille Oseaan, Atlantiese Oseaan

Tuis

It lives in shallow coastal and brackish waters. During the day it attaches itself to surfaces, especially seagrass.1

Lengte

1 cm tot 4 cm (0,4 in tot 1,6 in)1

Topspoed

omtrent 0,35 km/h (0,22 mph)

Swem, rowwe skatting

Wat eet dit?

It mostly feeds at night in open water on zooplankton such as fish larvae and tiny crustaceans. It may also catch prey while attached to surfaces during the day.1

Hoe om dit te herken

Has a transparent bell lined with about 60 to 80 tentacles1
Gonads are orange, red or violet in females and yellow-brown in males1
The tan manubrium (mouth structure) hangs down in the middle of the bell1
Bell is usually 1 to 3 cm across; a tentacle can be twice the bell's diameter when fully extended1

Gifkrag

Steektentakels

Duisende piepklein steekselle skiet af wanneer iets aan hulle raak.

Wat doen sy gif as dit byt of steek?

Its sting can cause pain, a swollen throat, chest tightness, muscle cramps, neuropsychiatric changes (effects on mood, thinking or behaviour) and anaphylactic shock, a severe allergic reaction.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.

In much of its range the sting is strong enough to cause serious symptoms. Stinging incidents have been reported from East Asia, Europe and the Atlantic coast of the United States. Off North America's northeast Pacific coast, its sting cannot be felt and it is considered harmless to people.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

Feite

Some scientists think the clinging jellyfish may be a group of closely related species, because its sting and body shape vary from place to place.1

The jellyfish appear once the water warms to about 17 to 18 °C, so they follow a yearly pattern and sometimes appear in large numbers at once.1

The medusa (jellyfish) stage usually lasts no more than three months, but the polyp stage can last for years.1

Polyps can split into several new polyps by budding.1

In Europe, the species is non-native and has been found in the Mediterranean and along the Atlantic coast from Portugal to Norway and Sweden.1

Mite-breker

Mite: The clinging jellyfish is harmless everywhere.

Waarheid: Its sting is harmless off the northeast Pacific coast of North America, but it can be strong and dangerous in East Asia, Europe and the Atlantic coast of the United States.1
