A cuticular plate (called a carapace) covers the cephalothorax, much like the shell of a crab. Eyes. Spiders typically have multiple eyes (up to eight) set in two rows at the front of their carapace.

Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or as a type of pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, used to inject venom into prey or a perceived threat.
