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

Detailed explanation-3: -Bilateral symmetry involves the division of the animal through a sagittal plane, resulting in two mirror-image, right and left halves, such as those of a butterfly, crab, or human body. Animals with bilateral symmetry have a “head” and “tail” (anterior vs. posterior), front and back (dorsal vs.

Detailed explanation-4: -Annelids and arthropods are bilaterally symmetrical, that is, the body can be divided into two identical halves only along one imaginary plane.
