Covers the electron microscopic anatomy of arthropod sensory organophotoreceptors, chemoreceptors, and others in relation to function, behavior, and environment. The authors show how each sensory receptor is finely tuned to detect the necessary information in the arthropods surroundings and how the sensory receptors dynamically change their fine structures according to their functionaland adaptational states. The atlas thus provides an important bridge between the physiology and morphology of arthropod sensory receptors.
