What is the venom gland in a spider?
Quick Answer
A spider venom gland produces venom used mainly to immobilize prey and for defense. The venom is delivered through fangs called chelicerae.
The Full Story
Spider venom glands are specialized organs that make toxic mixtures of proteins and other compounds. The venom is usually injected through the spider’s fangs, which are part of the mouthparts known as chelicerae. Most spider venom is designed to subdue insects and other small prey quickly, although a few species have venom that can affect humans more seriously. Different spider species produce very different venoms, reflecting their hunting styles and prey preferences. Scientists study spider venom for clues about nerve function and potential medical uses.
