Is a spiders an insect?
No, spiders are members of the class Arachnida. They are arachnids, not insects.
Spiders have eight legs, but insects don't. Every insect has six legs. If an animal has more than six legs, then it is not classified an insect. Spiders have only two body parts, which insects do not have. All insects have only three body parts: head, thorax and abdomen. Because the spider has differences from an insect, it is classified under arachnids.
