Clinging jellyfish

Gonionemus vertens
O imenu: It is called the clinging jellyfish because during the day it attaches itself to surfaces, such as seagrass, using the adhesive patches on its tentacles.1

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

Živi v
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
Tihi ocean, Atlantski ocean
Domov
It lives in shallow coastal and brackish waters. During the day it attaches itself to surfaces, especially seagrass.1

Kaj je?
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

Kako nevarna je za ljudi?

Nevarnost za ljudi: ResnoPo piku je potreben zdravnik. Smrtni primeri so zelo redki.

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

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

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

2

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

3

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

4

Polyps can split into several new polyps by budding.1

5

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

Razbijalec mitov

Mit: The clinging jellyfish is harmless everywhere.

Resnica: 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

Medusae release tens of thousands of eggs and sperm into the sea. The fertilised young become planula larvae, which settle on the seabed as tiny polyps.1
