The Sydney funnel-web spider is a venomous spider from eastern Australia. It is found mostly within about 100 km of Sydney. Its bite can cause serious illness or death if it is not treated, so it is one of the most important spiders to know about in the region.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

The venom contains delta-atracotoxin, which affects the ion channels of nerves and makes it highly toxic to humans and other primates. Symptoms can include intense nausea, vomiting, excessive saliva, muscle twitching, breathing difficulty, confusion and unconsciousness. In severe cases, symptoms begin in under one hour, with a median time of 28 minutes in one study.1

Ana hatari gani kwa watu?

Hatari kwa watu: AnauaMmoja wa wanyama hatari zaidi duniani.

A bite can cause serious illness or death if untreated. Children are at particular risk: in one study, 42% of severe cases were children. There is at least one recorded case of a small child dying within 15 minutes of a bite. Only the Sydney funnel-web and the northern tree-dwelling funnel-web have been known to cause fatal bites in humans. There have been no recorded deaths since antivenom became available in 1981.1

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Hufanya nini akiogopa?

When threatened or provoked, it rears up on its hind legs, shows its fangs and may bite repeatedly while holding on tightly.1

Akiuma

  • A Sydney funnel-web bite is a medical emergency that needs immediate hospital treatment. Guidelines recommend two vials of antivenom, or four if symptoms are severe, with patients assessed every 15 minutes and more vials given if symptoms do not resolve.1
  • Osha jeraha na ulipoze. Tafuta msaada wa kitabibu kama maumivu ni makali au mtu anajisikia vibaya.
  • Australia, chukulia kuumwa na buibui yeyote mkubwa mweusi kama kuumwa na buibui wa utando wa faneli: Kubana na kutotikisa: funga bandeji nyororo kwa nguvu juu ya jeraha kisha mguu au mkono mzima, weka banzi, na umweke mtu bila kutikisika kabisa hadi msaada ufike.

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.
  • Akikuuma: 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

1

Males can survive submersion in water for up to twenty-four hours by trapping air bubbles on the hairs of their abdomen.1

2

One dose of antivenom needs around 70 milkings from a Sydney funnel-web spider.1

3

The most antivenom vials used to treat one bite is twelve, for a 10-year-old boy bitten in February 2017 by a male hiding in a shoe.1

4

Female spiders are long-lived and spend most of their time in their burrows. No severe envenoming by a female has been reported.1

5

Activity increases after heavy rain, because burrows can become flooded.1

Kuvunja dhana potofu

Dhana potofu: The male and female funnel-web spiders were thought to be different species.

Ukweli: In 1927, Anthony Musgrave showed from anatomical similarities that the male Euctimena tibialis was the male of Atrax robustus, the same species as the female.1
