The Biomechanics of Web Building and Prey Capture in Orb-Weaving Spiders

Quick fact

Orb-weaving spiders can adjust the stiffness and stickiness of different sections of their web to optimize prey capture, and some can even tune the web's tension to detect the vibrations of a struggling insect from meters away.

Why this is interesting
