Spiders' Methods of Hunting              27


            of creation. It is God Who created all living creatures, plants, animals, and
            insects. God has infinite power, knowledge, intelligence, and wisdom:
                 'Lord of the heavens and the earth and everything between them, the
                 Almighty, the Endlessly Forgiving,' (Surah Sad: 66)


                 The Trap-door for Living in the Desert

                 Desert climates can be lethally hot for many living creatures.
            Nevertheless, some creatures have skills which enable them to survive in
            the desert despite the heat. Either their hunting techniques, the
            construction of their bodies, or their modes of behaviour enable them to
            live comfortably in a desert environment. One species of the subject of this
            book, the spider, possesses the characteristics necessary for living in the
            desert. This living thing, known as the "trapdoor spider" uses its insulated
            home in the desert floor both to protect it from the heat and as a trap to
            catch its prey.
                 First of all the spider digs a burrow in the ground. It sticks tiny bits
            of earth together with a special fluid it produces and plasters the inside of
            the tunnel. This process strengthens the walls against the danger of
            collapse. Later it covers the walls in a thread it makes. This plastering
            technique is similar to the thermal insulation technique we use today. In
            this way the inside of the nest is made resistant to the high desert
            temperatures outside.
                 We mentioned how the second feature of the nest was its use as a
            trap. The spider makes a cover for the nest out of its own silk. One side of

            this is attached by a hinge made of strong thread to the nest, turning it
            into nothing less than a door. This door also helps the spider conceal itself
            from its prey. It camouflages the cover with bits of brush, scrub, and soil.
            Then it stretches taut threads under the leaves, from the outside of the
            nest in. When an insect approaches the nest and steps on the leaves or the
            earth, the underground threads start to vibrate. Thanks to these vibrations
            the spider can tell that prey is near. When everything is in position, the
            spider enters its nest and waits for its prey.
