The Hexapoda class, insects, is the largest class within the arthropod phylum. The class is also the most diverse group of animals within the animal kingdom. Like all other arthropods, insects are invertebrates with segmented bodies and exoskeletons made of chitin.
What are the common characteristics of arthropods?
All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.
What is difference arthropod and insect?
