"Chelicerous" Meaning

Chelicerous refers to something that is having chelicerae, which are appendages similar to mouthparts found in certain arthropods, such as spiders, scorpions, and ticks. Chelicerous organisms typically use their chelicerae to capture and inject venom into their prey. The term "chelicerous" can also describe the characteristics or features of these organisms, such as their simple eyes, segemented bodies, and jointed limbs.
