Relating to the chelicerae, which are the pincerlike mouthparts of spiders, scorpions, and other arachnids.
From Greek 'chele' (claw) plus 'keras' (horn), with the adjective suffix '-al.' Formed by zoologists to describe anatomical features of arachnids in scientific terminology.
Chelicerae are basically the spider's Swiss Army knife—they can inject venom, sense prey, manipulate food, and handle mating displays all with the same tiny weapons.
