Spiders: In Pursuit of Prey - by Harry Gardner

SUMMARY

There are over 36.000 species of spiders. Spiders are arachnids and can be found everywhere, from deserts to mountain peaks and even underwater. They can live indoors and outdoors. Most of them are small and harmless to us even though they can have a bite full of venom.

Their bodies have two parts, eight legs and a hard outer skeleton called (exoskeleton). About half of them also have glands in their abdomen that can produce silk, which is sticky, made of protein and used to catch prey. They reel out the silk strand by using their hind legs. Depending on the spider, the silk web may be different - strong and stretchy, round, triangular, sheet or tangle.

The other half of species that do not produce silk are called wandering spiders - they just wait until their prey passes by so as to catch it!

Spiders are predators that eat insects like flies and mosquitos, so they can be good for pests control. Spiders don't have teeth, so to digest their prey they spit digestive juices on the insect to liquefy it and then suck it.
