The Chelicerata are a sub- phylum of the Arthropods. The sub-phylum consists of only two classes: the Arachnids and the Merostomata. The Merostomata are the extinct Eurypterids and the horseshoe crabs (Xiphosura).
Arachnids are arthropods in the class Arachnida (/ ə ˈ r æ k n ɪ d ə /) of the subphylum Chelicerata. Arachnida includes, among others, spiders , scorpions , ticks , mites , pseudoscorpions , harvestmen , camel spiders , whip spiders and vinegaroons .
The subphylum Chelicerata is one of the five subdivisions of the phylum Arthropoda, with members characterized by the absence of antennae and mandibles (jaws) and the presence of chelicerae (a pincer-like mouthpart as the anterior appendage, composed of a base segment and a fang portion).
