Detailed explanation-1: -In this respect, arthropods are built like humans are; the right half of an arthropod is a mirror image of its left half-this is called bilateral symmetry (bi = two, latus = side).

Detailed explanation-2: -Animals with bilateral symmetry have a “head” and “tail” (anterior vs. posterior), front and back (dorsal vs. ventral), and right and left sides.

Detailed explanation-3: -All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages.

Detailed explanation-4: -Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.

Detailed explanation-5: -A condition in which the right and left sides of an item (e.g., a shape or an animal) are mirror images of one another. For example, since the right side of the human body generally mirrors the left side, humans are bilaterally symmetric.
