Spider Wikipedia

In some species males mate with newly-molted females, which are too weak to be dangerous to the males. Females lay up to 3,000 eggs in one or more silk egg sacs, which maintain a fairly constant humidity level. Males of the genus Tidarren amputate one of their palps before maturation and enter adult life with one palp only. The palps are 20% of the male's body mass in this species, and detaching one of the two improves mobility. In the Yemeni species Tidarren argo, the remaining palp is then torn off by the female. The separated palp remains attached to the female's epigynum for about four hours and apparently continues to function independently.

Each of the eight legs of a spider consists of seven distinct parts. Although all arthropods use muscles attached to the inside of the exoskeleton to flex their limbs, spiders and a few other groups still use hydraulic pressure to extend them, a system inherited from their pre-arthropod ancestors. The only extensor muscles in spider legs are located in the three hip joints . As a result, a spider with a punctured cephalothorax cannot extend its legs, and the legs of dead spiders curl up.
