The northern tree-dwelling funnel-web spider is a large spider from eastern Australia. It lives mostly in trees, from South East Queensland to the Hunter River in New South Wales. Its venom can be deadly to people, so it is important to know what it looks like.1

Tuis

It lives in rotting logs, branches, and hollow furrows and pipes of trees, especially tallowwood, as well as in epiphytes. It has been recorded up to 30 m above the ground. Roving males are found after rain and at night, from late October to early February, and they shelter during the day.1

Lengte

Topspoed

Wat eet dit?

Wood-boring beetles are likely to be a main prey item, based on the spider's tree-dwelling habitat.1

Hoe om dit te herken

Has a glossy black carapace (the hard upper shell of the body).1
Chelicerae (fang-bearing parts), legs and abdomen are matte black or dark brown.1
The top of the abdomen may have a plum or purplish tinge.1
Body length is 40-50 mm, the largest of the funnel-web subfamily Atracinae.1
Cannot jump.1

Word dikwels verwar met: The ground-dwelling Darling Downs funnel-web spider (Hadronyche infensa) is very similar. Male northern tree-dwelling funnel-web spiders have a knobby spur on the tibia (a leg segment) of the second pair of legs, which male Darling Downs funnel-web spiders lack. Trapdoor spiders are browner overall.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

The venom is potentially deadly to humans and is regarded as the most toxic of the venoms in the family Atracidae. Symptoms can start within 15 to 20 minutes. Common symptoms include sweating, high blood pressure, a fast heart rate, muscle spasms, nausea, vomiting, changes in consciousness and pain at the bite site. Fluid in the lungs (pulmonary oedema) is frequent and comes on early.1

Hoe gevaarlik is dit vir mense?

The venom is potentially deadly. Of eight recorded bites, five caused severe symptoms of envenomation. Because the spider is larger than the Sydney funnel-web, it may inject more venom, which could make it possibly the deadliest venomous spider in the world per volume of venom.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

When threatened, it rears up, displays its fangs, and drops of venom appear on the fang tips.1

As dit byt

Pressure bandages and immobilising the patient can significantly delay the onset of symptoms. This remains a critical part of managing a bite from an Australian funnel-web spider.1
Was die byt en koel dit af. Kry mediese hulp as die pyn erg is of die persoon sleg voel.
In Australië, behandel enige byt van 'n groot swart spinnekop as 'n tregterwebspinnekop-byt: Drukimmobilisasie: draai 'n stewige elastiese verband oor die byt en dan op oor die hele arm of been, spalk dit en hou die persoon heeltemal stil totdat hulp opdaag.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly
