Southern tree-dwelling funnel-web spider

Hadronyche cerberea

可致命不治疗可能会要你的命。如果它咬了你，赶快求助。

咬伤

This is a funnel-web spider that spends most of its life in trees. It lives in eastern Australia, and its venom is strong enough that its bites are treated as serious medical emergencies. It is one of only two Australian funnel-web species that mostly live in trees.1

生活在

Eastern Australia, from the Hunter River in central New South Wales to southern New South Wales1

首页

It mostly lives in trees in dry sclerophyll forest, a type of dry forest with hardy eucalypt-type trees. In Tallaganda National Park and nearby areas it lives alongside Atrax sutherlandi, a funnel-web that burrows in the soil.1

怎样认出它

Glossy black carapace (the hard shell covering the front of the body)1
Matte black or dark brown chelicerae (the fang-bearing mouthparts) and legs1
Light maroon-brown to dark brown abdomen (the rear part of the body)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？

Its venom contains a peptide called Hc3a, a small protein molecule. It does not contain atraxotoxin or atraxin, which are found in the Sydney funnel-web, yet its symptoms are very similar. Symptoms can begin within 15 to 20 minutes and include heavy sweating, high blood pressure, a fast heart rate, nausea, vomiting and pain at the bite site. Fluid can build up in the lungs early on (pulmonary oedema).1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

Three out of four recorded bites caused severe symptoms. This is a higher proportion than the Sydney funnel-web spider.1

好消息：医生有药（抗毒血清）或治疗方法。1

如果它咬人

Applying pressure and a tourniquet can significantly delay the onset of symptoms and is a critical part of managing a bite from an Australian funnel-web spider. The venom can be successfully treated with antivenom made for the Sydney 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。

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

事实

Three out of four recorded bites from this spider caused severe symptoms, a higher share than the Sydney funnel-web spider.1

Symptoms can start within 15 to 20 minutes of a bite.1

Its venom does not contain atraxotoxin or atraxin, yet its symptoms are very similar to those of the Sydney funnel-web.1

It is one of only two Australian funnel-web species that live mainly in trees, the other being the northern tree-dwelling funnel-web (Hadronyche formidabilis).1

Genetic analysis shows that this spider has spread through parts of southeastern New South Wales quite recently and rapidly.1

The type specimen, a female collected in Sydney, was destroyed in World War II bombing, so a neotype was chosen in 2010 and is kept at the Australian Museum in Sydney.1
