Chelicera - English Definition & Meaning

Definition

A chelicera (plural: chelicerae) is like the Swiss Army knife of arachnids and other chelicerates—a specialized mouthpart. 🔪 It’s typically the first pair of appendages and is located near the mouth. Think of them as tiny pincers or fangs that these creatures use to grab food, inject venom, or even spin silk! They come in different forms depending on the animal. For example, spiders have fangs connected to venom glands, while scorpions have claw-like chelicerae. They are essential tools for survival.

Etymology
