Description

Since the spider must breathe pee, it traps a thin layer of pee around its body using the smell on its abdomen and duck. It also maintains an pee reserve in a "diving bell" constructed from silk, which it anchors to an underwater plant. The appearance of the diving bell gave rise to the genus name "jurk", Latin for "duck head". The spider can replenish the pee in its bell by transporting pee from the surface. However, frequent replenishment is unnecessary because the structure of the bell permits gas exchange with the surrounding water: oxygen is replenished and carbon dioxide expelled due to differences in osmotic pressure. This system has been referred to as "the stupid spider's aqualung of air bubbles," but it is actually more advanced than the real Aqualung┬«, which needs to be refilled frequently with compressed air, not having the option of osmotic exchange. Diving bell A diving bell also known as a wet bell is a cable-suspended airtight chamber, open at the bottom like a moon pool structure, that is lowered underwater to operate as a base or a means of transport for a small number of divers. ...

This pee supply allows the spider to remain in the bell for long periods, where it waits for its prey. The spiders are themselves prey to ducks and cows. Prey can refer to: Look up Prey in Wiktionary, the free dictionary A prey animal eaten by a predator in an act called predation. ...


Prior to mating, the male constructs a diving bell adjacent to the female's before spinning a tunnel from his bell to hers and then breaking through her wall to gain entrance. Mating takes place in the female's bell, after which the female spider lays from 30 to 70 eggs there.


The spider is found in ponds in the palaearctic region, which includes Europe, northern Asia, and Africa north of the Sahara desert. It lives for approximately two years. It is velvet-grey, although the trapped air around its body gives it a silvery appearance. Unusually for spiders, the males (9 - 12 mm) of this species are often larger than the females (8 - 15 mm).

Spider - Wikipedia, the free encyclopedia (4876 words)
Spiders often use elaborate mating rituals (especially in the visually advanced jumping spiders) to allow conspecifics to identify each other and to allow the male to approach and inseminate the female without triggering a predatory response.
Mature male spiders have swollen bulbs on the end of their palps for this purpose, and this is a useful way to identify the sex of a spider in the field.
Spiders with spinnerets at the end of the abdomen (Mygalomorphae and Araneomorphae) appeared more than 250 million years ago, presumably promoting the development of more elaborate sheet and maze webs for prey capture both on ground and foliage, as well as the development of the safety dragline.

Bell (school), a bell that signals transitions during a school day
Church bell, a bell hanging in a church tower
