Spider Clipart

About 400 million years ago, the first spiders appeared on the earth (Araneae lat.), descended from a crab-bearing ancestor. Now there are over 40,000 species of spiders.

Many insistently call spiders insects, although it is a separate detachment and a separate class - arachnids (Arachnida, subtype Chelicerata, type Arthropods). Spiders differ in many ways from insects.

First of all, they do not have six legs, but eight. Spiders have special forelimbs with poisonous claws - chelicera. The maximum that can be experienced from the bite of a large spider - burning, pain and fever. However, spiders are not the first to attack. If a spider accidentally falls from a spider's web to a person, you need to gently blow it away, and not beat - otherwise it will get scared and can bite.

The eye of the spiders is usually 8, sometimes 6 or very rarely - 2. The males on the forelimbs have bulbuses into which it places the sperm for the fertilization of the female. Some males are already ready in advance for death after mating - they allow the female to eat herself, others intend to fight for her life and seek to escape. Some male spiders have prepared in advance to death after pairing - they allow the female to eat themselves, others are going to fight for their lives and seek to escape.
