To learn more about the anatomy, click on the different body parts of this spider !!
The body of spiders is divided in two major parts. The first (anterior) part of the body is called the cephalothorax.
Spiders are different from insects. The body of insects is divided in three major parts: head, thorax and abdomen. If we compare a spider with an insect, the cephalothorax is a combination of head and thorax.
Spiders have no antennae and no wings.
The abdomen is the posterior of the two body regions of a spider. On the tip of the abdomen we find the spinnerets. These are very small organs that produce silk for making webs. Often, spiders have 6 of these small spinnerets.
Spiders have 8 legs. This sets them apart from insects, which have only 6 legs. The legs are usually long and hairy. The hairs on their legs are used to pick up scents, sounds, vibrations and to detect air currents. Most spiders can move very fast, and some can also jump.
At the front of the cephalothorax we find a pair of chelicera. These fan-like or claw-like appendages are mouthparts. In spiders these chelicera are hollow and contain venom glands (or they are connected to these glands). The spider uses them to inject poison into its prey.
Spiders have a pair of palps (or pedipalps) on the front of the cephalothorax. In male spiders, the ends of these palps are modified into complicated structures that are used for mating.
