Trapdoor spiders, of which there are about 50 species in the Liphistius genus, are found in China, Japan and south east Asia. These spiders rarely leave their underground burrows, and seal the entrance with a disguised web trapdoor. When an unsuspecting insect touches one of the silk fishing lines, or trip wires, that radiate out of the entrance, the trapdoor springs open and the spider grabs it prey.
