All spiders spin silk, produced from specialized glands at the tail of the abdomen called spinnerets. Frequently many threads are spun together, each one being perhaps less than one hundredth of a millimetre in diameter. The liquid silk pulled into threads is spun together. The liquid silk pulled into threads dries chemically, rather than due to the action of air and weight for weight is considerably stronger than steel.
•Fear of spiders is called Arachnophobia
•It is one of the most common fears among humans
•Spiders are not insects. Insects have three body parts and six legs

•The smallest spider is the Patu Marplesi. You could fit 10 of them on the end of a pencil
•Spider silk is possibly the strongest material in the world!
•Scientists believe that if they gathered the same weight of spider web as a piece of steel, the web would be much stronger than the steel!
•As hard as scientists try, they cannot match or copy the silk.
