A unique and dangerous animal

The spider is a member of the animal kingdom. They are also included in Arthropod phyla, together with crustaceans, insects, millipedes, centipedes and other animals with clearly segmented bodies. Spiders can create powerful webs to catch prey by setting traps to trap them.

Spiders share Arachnida classes with mites, lice, scorpions, harvesters ("father longlegs") and other animals with eight legs. It is also important to know what a spider is. They are not insects or "insects", even though they are distantly related.

What is Spider?
The spider (the Araneae order) is a breathing arthropod that has eight legs and chelicerae with fangs that inject toxins. They are the order of the greatest arachnids that have ranked seventh in the total species diversity among all other oration organisms.

Spiders can be found all over the Antarctic world. Anatomically, spiders with other arthropods. Unlike insects, the spider has no antenna.

Spiders have the most centralized nervous system of all arthopods. Unlike most arthopods, spiders do not have extensor muscles in their legs and otherwise extend them with hydraulic pressure.

Spider webs vary greatly in size, shape and number of sticky yarns used. The spiral ball network is one of the earliest forms and the spider that produces crumpled nets is more numerous and varied than the orb-web spider.
