In addition to transporting respiratory gases, the fluid also moves nutrients and wastes throughout the body. Techniques and organelles involved in respiration differ among arthropods depending on life stage, body size, and permeability of the external surface. Gases are respired across the cuticle ...
arthropods, entomologyThe adults of Donacia simplex are found on the roots of aquatic plants during the winter. Oxygen diffuses from the gas spaces in the roots into the gas-filled cocoons through the root scar. The root scar slows down the diffusion of oxygen into the cocoons. During the ...
arthropods, entomology, insectsWhen totally submerged beneath the surface of the water, Belostoma and Ranatra respire by means of air stores which adhere to their bodies and which communicate with the spiracles. The mesothoracic spiracle lies between the prothorax and mesothorax; the metathoracic ...
