How do spiders move their limbs?
The spider's legs move using a combination of fluid pressure and muscle flexion. .. The first two pairs are in front of the spider's center of gravity, and the latter two pairs are behind that center of gravity. During forward movement, the two front pairs bend inward, creating a force that pulls backwards. 2019
