Slingshot spiders catch insects by releasing cone-shaped webs at over 1m/s in response to sound.

Slingshot spiders, or ray spiders, use a unique hunting technique, forming a cone-shaped web they release at high speeds to catch insects before they come into contact with the web. Researchers found these spiders can detect sound vibrations and deploy their webs at up to 50g, reaching speeds of nearly 1m/s, to capture prey within 38 milliseconds. This active hunting strategy, involving sound-sensitive hairs on their legs, is faster than insects can react, ensuring a successful capture.
