Pacific sea nettle

Chrysaora fuscescens
O imenu: The name 'nettle' refers to its sting, which is like that of the stinging nettle plant. Its genus name, Chrysaora, is Greek for 'he who has a golden armament', after the golden colour of its bell.1

The Pacific sea nettle is a large jellyfish with a golden-brown bell and long, trailing tentacles. It lives in the cool and temperate coastal waters of the northeastern Pacific Ocean, from southern British Columbia down to Mexico. Its sting is irritating, but it is rarely dangerous to people.1

It lives in temperate to cooler coastal waters. Its numbers peak in late summer, and it has become very abundant off the coast of Oregon. Dense swarms can clog fishing nets and water intakes.1

Kaj je?
It drift-feeds, hanging its stinging tentacles in the water like a large net to catch prey as it floats past. It eats zooplankton, crustaceans, salps, pelagic snails, small fish, fish eggs and larvae, and other jellyfish.1

Kako jo prepoznaš

  • Long, spiralling whitish oral arms1
  • 24 undulating maroon tentacles that can trail up to 4.6 m behind it1

Moč strupa

Ožigalne lovke

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

Kaj naredi njen strup, ko ugrizne ali piči?

When prey touches the tentacles, thousands of stinging cells (nematocysts) fire barbed stingers that inject venom. The venom contains proteins, including proteases and pore-forming toxins, which can disrupt cell membranes and tissues. The venom is effective against prey and humans, but is typically not lethal to people.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

Its sting is often irritating and possibly mildly painful to people, but it is rarely dangerous. It is typically nonlethal to humans.1

Kaj naredi, ko se prestraši?

Its stinging tentacles are its main defence, although some animals, such as leatherback turtles, are not bothered by the sting.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

Small fish and crabs sometimes hide inside its bell, where they may feed on it.1

2

It uses light-sensing organs called ocelli to migrate from deep water up to the surface.1

3

It swims by jet propulsion, squeezing its bell to push water out, though it mostly floats.1

4

Its population may be growing because of nutrient pollution from human sources, which feeds algal blooms and the wider food chain.1

5

It is kept in many aquariums because of its bright colours and very long tentacles, and it is low-maintenance in captivity.1

Females hold fertilised eggs on their oral arms, where they grow into free-swimming larvae. The larvae settle, become polyps, and bud new polyps before developing into jellyfish. No number is given.1
