Trapdoor ambush

Expert Dr George McGavin finds a trapdoor spider's lair in the Central American forests. The trapdoor spider's home consists of a silk-lined tube with a lid made up of soil and debris to perfectly camouflage their booby trap. They wait patiently for prey to walk past the trapdoor, sensing movement with ultra-sensitive hairs on their legs. When the prey gets close enough, the trapdoor spider springs its trap in a split second with incredible accuracy.
