对人的危险: 致命世界上最危险的动物之一。

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

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

它吃什么？

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

怎样认出它

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

常被误认为： 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

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 致命世界上最危险的动物之一。

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

好消息：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

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

如果它咬人

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
清洗咬伤处并冷敷。如果疼得厉害或感到不适，就去看医生。
在澳大利亚，任何大型黑蜘蛛咬伤都要当作漏斗网蜘蛛咬伤处理：加压固定法：用有弹性的绷带紧紧缠住咬伤处，再缠满整条肢体，用夹板固定，让人完全不动，直到救援到来。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识
