A spider on the other hand is an arthropod, made up of a cepolothorax joined to an abdomen. It does not grow wings at any stage of its life. It is eight-legged, and in place of the normal insect antennae it has pedipalps. A spider generally has eight simple eyes or it could have six eyes e.g. a spitting spider. Depending on the species the eyesight may be well or poorly developed.
