Arthropods' General Characteristics:
Arthropods have jointed appendages with a hard exoskeleton called a cuticle made out of Chitin protein. They have an organ-system level of organization with triploblastic tissue layers of the epidermis, mesodermis, and endodermis. They have an alimentary canal with a mouth and an anus, and they have an eucoelomatic body cavity lined with the mesoderm. There are 5 recognized subphyla in the Phylum Arthropoda: Trilobita, Chelicerata, Crustacea, Myriapoda, and Hexapoda.
