Complete Spider Control Catalog Spiders have a characteristic appearance which is easily recognized by most people. They possess eight legs which immediately separate them from insects, which have only six legs.
Spiders lack wings and antennae.
Young spiders, or spiderlings, resemble the adults except for size and, sometimes, coloration. All spiders have a pair of jaw-like structures, called chelicerae. At the end of each is a hollow, claw-like fang. Each fang has a small opening in the end through which venom is injected into the prey. Spinnerets, located at the tip end of the abdomen, are silk spinning glands used for web making.
