Are you afraid of spiders? Many people can answer "Yes, of course". But lets know something interesting about them. Its a big mistake to call spiders insects. In fact, the spiders belong to the order of arthropod type. The main difference between spiders and insects is the number of legs. Insects have only six and spiders have eight feet. Of course, they are close relatives, because the spiders and insects belong to the Arthropod type. In nature, there are over forty one thousand species of spiders! Amazing! Sometimes spiders have eight or six eyes, very rarely in some species two eyes. Spiders are all predators. They eat usually their relatives-insects. Catching the prey by means of the spiderweb, the spiders kill it with poison and inject it with digestive juice. Isnt this scary for you? Anyway, we should be more attentive if we see any spider in the street or forest. They can be dangerous, of course.
