chelicera
Quick Summary
The chelicerae are the first pair of appendages in arachnids, located in front of the mouth. These appendages are often specialized as fangs or pincers and are used for capturing and manipulating prey. In spiders, the chelicerae contain venom sacs and are used to inject venom into their prey. Some arachnids, like scorpions, have chelicerae that are used to crush food. The chelicerae are a defining characteristic of the subphylum Chelicerata, which includes spiders, mites, scorpions, and horseshoe crabs.123456

The first pair, the chelicerae, often have claws or fangs. They are used to capture prey (spiders), transport a spermatophore (sunspiders, some mites and ticks), produce sounds (sunspiders, some spiders), cut strands of silk (web-dwelling spiders), and produce silk (pseudoscorpions). The pedipalps, the second pair, likewise are often highly…
