insect
insect, (class Insecta or Hexapoda), any member of the largest class of the phylum Arthropoda, which is itself the largest of the animal phyla. Insects have segmented bodies, jointed legs, and external skeletons (exoskeletons).
How many arthropod classes are there?

What are the main features 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 unique about the appendages in arthropods?
As mentioned earlier, the appendages of arthropods are distinct from those of annelids in that they are jointed. In some species, the appendages are also branched, a condition called biramous. Unbranched appendages are called uniramous. Jointed appendages allow the animal much greater flexibility and range of movement.
