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

Anaishi

Freshwater in mainland Europe, the British Isles and central to northern Asia, reaching as far south as Iran and north to Siberia. Japan has a very similar subspecies.1

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

The bite is reputedly painful, but there is no solid evidence of serious harm to people. Recent confirmed reports are lacking.1

Akiuma

Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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

Kuvunja dhana potofu

Dhana potofu: Its bite is very painful and causes vomiting and fever.

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