1. Adjective:
   • Of or relating to chelicerae: Pertaining to the specialized appendages or mouthparts found in certain arthropods, particularly arachnids.
   • Resembling chelicerae: Having a form or structure similar to these pincer-like or fang-like appendages.

Usage and Examples

• Adjective:
  • The spider uses its cheliceral fangs to inject venom. (This describes the fangs that are the spider's chelicerae.)
  • Scientists studied the cheliceral morphology of different scorpion species. (This indicates the study is focused on the form and structure of the chelicerae.)

Advanced Usage

• In taxonomic description: The term is used in detailed biological and zoological descriptions to specify features related to these mouthparts.
  • The key diagnostic feature is the cheliceral dentition pattern. (This refers to the arrangement of teeth on the chelicerae.)

Variants and Related Words

• Chelicera (noun, plural: chelicerae): The actual appendage itself, typically the first pair of appendages in arachnids, horseshoe crabs, and some other arthropods, often modified into pincers or fangs.
• Chelicerate (noun): A member of the subphylum Chelicerata, which includes arachnids, horseshoe crabs, sea spiders, and extinct groups like eurypterids.
