Faktlar

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

Afsonalarni fosh qiluvchi

Afsona: Its bite is very painful and causes vomiting and fever.

Haqiqat: These effects are based on old, unverified reports. There is no solid evidence for them, and recent confirmed reports are lacking.1
