The gross morphology and physiology of the cephalothoracic respiratory apparatus of the freshwater crab (B. cunicularis) are discussed and compared to other decapod crustaceans. Histologically, the gill is composed of lamellae, afferent blood vessels, branchial excretory cells and an efferent branchial sinus. Under drought conditions, freshwater crabs are able to aerially respire by recycling water stored in the branchial chamber over the gills.
