Detailed explanation-1: -Most mites and ticks have oval-shaped bodies, with two body regions (prosoma and opisthosoma) that may appear fused together. The Acari are indeed small, many measuring a mere millimeter long, even as adults. Ticks and mites go through four life cycle stages: egg, larva, nymph, and adult.
Detailed explanation-2: -There is usually a pair of appendages attached to each segment. Unlike some arthropods, arachnids specifically have simple eyes. They also have four pairs of walking appendages and two additional pairs. They have two parts to their bodies, the cephalothorax and abdomen.
Detailed explanation-3: -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.
