The diving bell spider is the only spider known to live almost entirely underwater. It makes its home in clean freshwater across Europe and Asia. It is special because it breathes air that it carries down from the surface and keeps in a silk bell under the water.1

怎样认出它

Out of the water, it is mid to dark brown.1
Hairs on the abdomen give it a dark grey, velvet-like look.1
Underwater, an air bubble trapped by dense hairs on the abdomen and legs makes it look silvery.1
Males have a head-and-body length of 10 to 15 mm, and females 8 to 12 mm.1
It spends most of its time inside a silk diving bell, darting out to catch prey.1

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？

Reports describe a bite that is painful, with local swelling, vomiting and a slight fever that lasts 5 to 10 days. These reports are old and unverified, so the effects are not well confirmed.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。

The bite is reputedly painful, but there is no solid evidence of serious harm to people. Recent confirmed reports are lacking.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。

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

It is the only known spider that spends almost its whole life underwater, including resting, hunting, mating, laying eggs and overwintering. It surfaces only briefly to refill its air supply.1

Its diving bell is made of waterproof silk and lets gases pass through. Oxygen flows in and carbon dioxide flows out, so the bell works like a kind of gill.1

Nitrogen slowly leaves the bell, so the air bubble shrinks and the spider must keep refilling it.1

Unlike most spiders, the males are larger than the females, and they are more active hunters.1
