Spiders’ Legs Are Hydraulic Masterpieces The compressed-fluid system that arachnids use to move their limbs has inspired scientists and engineers. By Helen Czerski Share ...

Spider legs only have muscles for retraction, while extension is achieved via a hydraulic mechanism. In the spider’s body, a chamber filled with blood expands and contracts to control the ...

She said: 'Spiders do not have antagonistic muscle pairs, like biceps and triceps in humans 'They only have flexor muscles, which allow their legs to curl in, and they extend them outward by ...

Internal valves in the spiders' hydraulic chamber, or prosoma, allow them to control each leg individually, and that will also be the subject of future research, Preston said.

These high-speed, high-resolution videos eventually revealed that the male spiders appeared to be catapulting themselves by folding their two front legs against the female’s body at the spider ...

Internal valves in the spiders’ hydraulic chamber, or prosoma, allowed them to control each leg individually, and that will also be the subject of future research, Preston said.

Internal valves in the spiders’ hydraulic chamber also allow them to control each leg individually. When they die, they lose the ability to actively pressurize their bodies. That’s why they ...

Spider legs seem to have minds of their own. According to findings published in the Journal of the Royal Society Interface, each leg functions as a semi-independent “computer,” with sensors ...

They found that the spiders flipped backwards to cast their nets when they heard recordings that resemble flying insect sounds, and their isolated legs showed nerve reactions to a wide range of ...

Pelican spiders, which are sometimes referred to as "assassin spiders," feed on other creatures by capturing and manipulating them with their "long, spear-like" legs, according to a study ...
