Can spiders survive water?
Researchers have discovered how a species of air-breathing spider can spend its whole life under water, only venturing to the surface occasionally to replenish its air supply. The ‘diving bell spider’ or ‘water spider’ (Argyroneta aquatica) is the only spider that lives entirely under water.

Do spiders feel pain when you kill them?

Can spiders swim?
The spiders are also good swimmers, usually working from the sides of pools and off rocks. When disturbed or hauling in captured fish, they will plunge through the surface of the water and swim quickly to hide on the bottom.
