Spiders use hydraulic pressure to extend and move their legs. When they die the hydraulic pressure goes away and the legs relaxes and curl up.
Can spiders walk on water?The force of surface tension balances the spider’s weight, helping it to walk on water. Surface tension affects the top layer of water, causing it to behave like a stretched elastic sheet. It occurs because the attraction between water molecules is not balanced at the liquid surface.
