Question

difference between crustaceans and insect

Answer 1

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. Although the arachnids are easily differentiated from other arthropods, the distinctions between crustaceans and insects are present, but a bit trickier to spot at times.

Answer 2

Every crustaceans can not fly whereas every insects can fly... This is most common difference.
