Chilean six-eyed sand spider

Sicarius thomisoides

只是会疼会疼，但不会对你造成严重伤害。

咬伤吃：肉

The Chilean six-eyed sand spider is a small spider that lives in the deserts of northern and central Chile. It hides under rocks and comes out at night. Its venom has effects similar to those of the Chilean recluse spider, which is why it matters to people who live nearby.1

怎样认出它

Body length of 12 to 20 mm1
Active at night, with nocturnal habits1
Shelters under rocks on sandy ground1
Very common in urban areas with household waste1

常被误认为： Older records under the name Sicarius terrosus may actually describe other species, such as Sicarius levii. Names in older books can therefore be unreliable.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 an enzyme called sphingomyelinase D, which has effects similar to those of the Chilean recluse spider. In laboratory tests the venom broke down red blood cells (haemolysis) and damaged skin cells, and 50 μg was enough to cause dermonecrosis, or the death of skin tissue. The venom also broke down fibrinogen, a protein needed for blood to clot.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Laboratory work shows that the venom can damage human tissue. Adult spiders carry up to eight times the amount of venom tested, so bites from adults could cause more serious lesions.1

如果它咬人

清洗咬伤处，用冰袋冷敷止痛。如果疼得厉害、疼痛扩散或感到不适，就去看医生。

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

值得了解

事实

In 2020 a 20 mm spider was recorded preying on a 28 mm gecko, which is larger than the spider itself.1

Its venom breaks down fibrinogen, a clotting protein, faster than the venom of the Loxosceles species it was compared with.1

Scientists found that 50 μg of its venom was enough to cause dermonecrosis in laboratory tests.1

It is extremely common in Chilean cities where household waste is plentiful.1

谣言粉碎机

谣言： The species is known as Sicarius terrosus.

真相： The correct name is Sicarius thomisoides. The name terrosus was used for this species for a long time, but it was often used wrongly for other species too.1
