They have 8 eyes too. Also they are one of a few that can spin webs for capturing prey, they breathe with "book-lungs" and they are venomous and most insect are not.
Spiders are among the critters we would not want in our home, particularly the brown recluse and the black widow, which are common to the Yuma area and can deliver a poisonous bite. Though spiders are often found in outbuildings and wood piles, they get into small, dark corners in homes as well. Some have pretty bad eyesight, and they’re not really an offensive animal.
Spider bodies are fundamentally different from those of insects. Insect bodies generally are divided into 3 main parts -- the head, the thorax in the middle, and the abdomen at the end. In spiders, the rear-end abdomen is still there, but the first 2 segments, the head and thorax, are fused into a single unit referred to as the cephalothorax, cephalo being from a classical Greek root meaning "head."
Spiders possess 8 legs, in contrast to insects, who possess only 6. Also, many insects have compound eyes consisting of perhaps hundreds of small eyes, but nearly all spiders just have 8 eyes.

Another major feature not listed here is the fangs or 'chelicera', which are only found in spiders and related species (horseshoe crabs and sea spiders). Also, not all spiders have 8 eyes (for example the brown recluse has 6).
