An arthropod is an invertebrate, belongs to the phylum Arthropoda, which is largest phylum of the Animal Kingdom. Arthropods have organ system level of body organization and are bilaterally symmetrical, metamerically segmented body, triploblastic with true coelom. They possess pair of lateral jointed appendages and their body is covered with exoskeleton made of chitin.
