WebThe arthropod exoskeleton, formed from the epidermis, is composed of an outer waxy, water-resistant layer over chitinous horny and flexible layers. In terrestrial species this covering has small breathing holes (spiracles). By preventing dehydration the exoskeleton has allowed arthropods, especially insects, to invade most terrestrial habitats. WebDec 1, 2024 · Most arthropods breathe through a process called tracheal respiration. This involves the movement of air through a series of tiny tubes (tracheae) that branch off from the main respiratory organ (the spiracles). The spiracles are located on the sides of the arthropod’s body and open to the outside environment.
