Why are scorpions not incects?

Answer 1

Scorpions are not insects but are arachnids, like Spiders, and have eight legs and two main body regions, the prosoma and the mesosoma. The prosoma has two eyes on top and two to five eyes along each side (as many as five pairs). Even with all those eyes, scorpions can't see very well! Their eyes mostly tell movement and light from dark. The scorpion's four pairs of legs are attached to the prosoma as well. Scorpions find their way by feeling along with brush-like structures called pectines attached to the underside of the mesosoma, and fine sensory hairs to detect vibrations. Male scorpions also use the pectines to find an available female. The scorpion's tail, called the metasoma, ends in a sharp stinger with venom glands.
