💡 Trivia Spiders move their legs using biological hydraulics

[Beatriz9]

Their blood powers the hydraulic systems in their legs; they’re able to increase and decrease the pressure in individual legs to move them.

In fact, they can increase the pressure in their legs up to eight times their resting blood pressure, allowing them to jump at least 50 times their own height!

The only muscles that spiders have in their legs are in their three hip joints.
