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

Kuogelea, makadirio

Hula nini?

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

Nguvu ya sumu

Mikono inayodunga

Maelfu ya seli ndogo za kudunga hufyatuka kitu kikizigusa.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

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

Hufanya nini akiogopa?

Its stinging tentacles are its main defence, although some animals, such as leatherback turtles, are not bothered by the sting.1

Akidunga

Toka majini na uondoe vipande vya mikono iliyonata (kwa glavu au kitambaa).
Kwa yavuyavu sanduku wa kitropiki: mimina siki kwenye sehemu zilizodungwa kwa angalau sekunde 30, omba msaada na uwe tayari kufanya CPR. Kwa mabotoli ya bluu na wengine wengi: suuza kwa maji ya bahari, kisha maji ya moto kupunguza maumivu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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

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

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

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

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