Along with arachnids, crustaceans and insects belong to the same group---arthropods. Sharing distinctive physical characteristics, such as absence of backbone, hard exoskeletons, jointed legs and segmented bodies, arthropods are easily distinguished from other animal groups.hile some species, such as coconut crabs, sand hoppers, woodlice and pill bugs dwell on land, crustaceans are generally found in water --- and usually oceanic --- regions. Adapting to their habitat, many insect species evolved wings --- two pairs for most and one pair for others.
