Chelicerate is a group in the phylum of Arthropods. They have segmented and jointed legs. The body of the chelicerates is divided into two parts, the cephalothorax and the abdomen. The head and the thorax regions are fused to form the cephalothorax. The abdomen have an unsegmented telson. There are six pairs of appendages which are present on the six segments of the cephalothorax. The chelicerae are often modified into claw-like structures. These acts as sensory organs, defence agent and helps in feeding. Spider, tick and scorpion all belong to subdivision. Chelicerata while termite belongs to subphylum Hexapoda.
