About This Book

A detailed anatomical and physiological study of the crayfish describes its external form and internal organs at successive growth stages, tracing development and functional organization. It analyzes feeding, respiration, circulation, locomotion, sensory structures, and reproductive processes, and links each activity to the underlying anatomy and mechanisms that supply tissues with materials for maintenance and growth. Observational methods and comparative remarks illustrate how close study of a single animal can illuminate general zoological principles, ecological distribution, and the relations between structure, function, and environment.
