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

E tshela kwa

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

Gae

It lives in clean freshwater with aquatic plants, such as lakes, ponds, canals, marshes and slow-moving streams. It builds its diving bell between submerged water plants.1

Tsela ya go e lemoga

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

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

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

Dintlha

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

Mosenyi wa ditlhamane

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

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