How Fast Is Trap-Door Spider Strike?

Trapdoor spiders strike from their burrows in just 0.03 seconds — far too fast for prey to register, let alone react. They never leave their burrow; food simply walks past, and the spider grabs it and disappears before the prey notices.

A trapdoor spider never leaves its burrow — it grabs prey and disappears in 30 milliseconds.

• Same pace as a koala walking
• A strike completes in 30 milliseconds
