This text investigates the physiological mechanisms that allow crustacea to adapt to diverse aquatic and terrestrial environments. A. P. M. Lockwood, a recognized zoologist, synthesizes existing research to explain how these organisms maintain homeostasis. The book provides a comprehensive framework for understanding the internal processes of crustaceans, focusing on how their biological systems respond to environmental stressors.

Experts recognize this work as a foundational reference for students and researchers in invertebrate physiology. Readers frequently note the technical density of the prose, which assumes a baseline knowledge of biological principles.
