Arthropods are animals with segmented bodies, six or more jointed legs, and a hard shell called an exoskeleton. There are three major groups of arthropods: insects (the largest group), arachnids, and crustaceans. All arachnids have eight legs, two body parts, and no antennae. Arachnids also have two other pairs of limbs. The first pair is for catching and holding prey; this is also where the poison sacs and fangs are located. Another pair is for feeling and manipulating prey.
Insects eat mostly plants, but a spider’s favorite food is insects. Some insects have mouth parts that are similar to a spider’s; the difference is that insects can chew, and spiders cannot. Spiders have fangs that are used for injecting their prey with paralyzing venom. Spiders then douse their prey with digestive juices to liquefy the prey. Then, the spider slurps up the insides of the prey’s body.
