Read the following passage carefully
WEB OF LIFE
(1) Did you always think that spiders were insects? Actually, spiders are arachnids and not inseca
They have eight legs, while insects usually have six. Spiders also do not have wings and antennze
that most insects have,
(2) Spiders make silk threads that they use in many different ways. They have glands in their abdomen
and release the silk threads through pores or 'spinnerets' to create the cobwebs that we dust away
The silk material is actually a complex protein substance. Some spiders even eat the damaged or
old webs to conserve the protein-rich used silk. A good lesson in recycling! With these strands, they
receive and send out signals to each other and express fear, recognition, anger, hunger or desire. In
the web, the spiders wait for an unsuspecting victim.
(3) They have no teeth and spiders feed by injecting a poison, which also acts as a powerful digestive
fluid, into their victims. Spiders are natural enemies of insects and help keep pests at bay. So the
next time you see a spider, remember that spiders are among our greatest friends!
The poison is useful for spiders as it
