The mosquito would become more prone to injury due to a weakening of its Exoskeleton.
Exoskeleton, a hard or flexible covering that supports and shields an animal's soft tissues. The phrase refers to the chitinous integument of arthropods, such as insects, spiders, and crustaceans, and includes the calcareous housings of sessile invertebrates like clams. The exterior waxy, water-resistant covering of the arthropod exoskeleton, which is made from the epidermis, is covered by chitinous, and flexible layers. This coating features tiny breathing openings in terrestrial species (spiracles). The exoskeleton has made it possible for arthropods, particularly insects, to overrun the majority of terrestrial ecosystems by avoiding dehydration. Exoskeletons of animals like the lobster have flexible joints that allow for remarkable mobility.
