Black sea nettle
The black sea nettle is a large jellyfish with a dark purple to nearly black bell. It lives in the Pacific Ocean off western North America, and it is rare to see except in big swarms that appear in some years. Its stinging tentacles can cause a painful sting to people.1

Indlela yokusibona
- The bell is an opaque dark purple to nearly black colour.1
- The edge of the bell has a lighter brown, net-like (reticulated) pattern.1
- The bell can reach about 1 metre across, and the oral arms can extend 5 or 6 metres.1
- There are marginal sense organs around the bell edge, one after every set of 3 tentacles, 8 in total.1
Ivamise ukudidaniswa ne: No other West Coast jelly that visits nearshore waters has this dark pigmentation, so the very dark colour is the main way to tell it apart.1
Amandla obuthi
Izinkulungwane zamaseli amancane ahlabayo ziyadubula uma kukhona okuzithintayo.
Ubuthi baso benzani?
Each tentacle is covered in thousands of microscopic stinging cells called nematocysts. When touched, they fire a filament that injects toxins, which can kill smaller prey or stun predators. In people, the sting is usually not lethal but is painful and can last for forty minutes.1
Siyingozi kangakanani ebantwini?
Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.The sting is usually not lethal to people, but it is painful and can last for about forty minutes.1
Senzani uma sesabile?
Its stinging tentacles fire venom-filled filaments on contact, which stun or deter anything that threatens it.1
Uma sihlaba
- Phuma emanzini bese ukhipha noma yimiphi imicu ehlabayo (ama-tentacle) (ngamagilavu noma ngendwangu).
- Kuma-box jellyfish asezindaweni ezishisayo: thela uviniga ezindaweni ezihlatshiwe okungenani imizuzwana engama-30, biza usizo futhi ulungele ukwenza i-CPR. Kuma-bluebottle nakwamanye amaningi: hlanza ngamanzi olwandle, bese usebenzisa amanzi ashisayo ngenxa yobuhlungu.
Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala
Hlala uphephile
- Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
- Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
- Uma sikuhlaba: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.
Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile
Kuphi emhlabeni?
Sikhulu kangakanani?
Side kangakanani?

Yizibalo nje kusiphequluli sakho. Akukho okulondolozwayo noma okuthunyelwa ndawo.
Sishesha kangakanani?
Amaqiniso
It is thought to be the largest invertebrate described in the 20th century.1
Its stomach is lined with fibrous vessels that attach to prey, and its mouth-like openings, called darkmaws, close when exposed to bright light.1
It was only officially described in 1997, after large groups were found on the Pacific coast.1
Its swarms seem to coincide with red tides, which are blooms of the zooplankton it feeds on.1
