Abetted by recent technological advances in scanning and transmission electron microscopy, as well as new preparative methods, these contributions examine crustacean anatomy, demonstrating (or at least inferring) the functions of morphological features. In addition to feeding and grooming, they alsoA classification system for crustacean setae based on the homology concept; decapod crustacean grooming; gill and embryo grooming in lithodid crabs; grooming structure and function in some terrestial crustacea; functional morphology of feeding; morphology of feeding structures; feeding mechanisms of the Mysidacea; functional morphology of feeding of euphausiids; development of the feeding apparatus in decapod crustaceans; evolution of the foregut.
