Chelicerata: History & Art

The subphylum Chelicerata (from Neo-Latin, from French chélicère, from Ancient Greek χηλή (khēlḗ) 'claw, chela' and κέρας (kéras) 'horn') constitutes one of the two major living subdivisions of the phylum Arthropoda, alongside Mandibulata. Chelicerates include the sea spiders, horseshoe crabs, and arachnids (including harvestmen, scorpions, spiders…
