How It Works

SPIDERS DON’T USE THEIR FANGS TO EAT

As an integral part of their anatomy, fangs give many spiders the power to puncture their prey and inject a fatal dose of venom. However, fangs also play a role in the actual masticatio­n of their food. Within the spider’s venom are digestive enzymes that begin to break down and liquidise the prey’s body before it enters the spider’s. Once the enzymes have partly dissolved the prey into a gooey meal, the spider will use its mouthpart to slurp it up. Toothed jaws, fangs and mandible-like structures called maxilla assist in moving and breaking down tissue.
