Scientists have known for more than 50 years that spiders use internal hydraulic pressure to extend their legs, but what isn’t known is if this hydraulic pressure is actively used to enhance or ...

Credit: Preston Innovation Laboratory, Rice University Spider legs only have muscles for retraction, while extension is achieved via a hydraulic mechanism. In the spider’s body, a chamber filled ...

Jumping spiders are different—they use a unique semi-hydraulic system. They don't have muscles to extend their legs and power the jumps. Instead, they extend their legs by increasing the ...
