"Biology of Antarctic Fish" offers a comprehensive examination of the biological aspects of fish in the unique environment of the Antarctic Ocean. The book addresses the latest findings on the adaptation mechanisms of fish to the extremely low temperatures found in the coastal waters of Antarctica. With a constant temperature of about -1.87 °C, which corresponds to the equilibrium between ice and seawater, the biology of these fish is analyzed at various levels of organization. The authors, Guido Di Prisco, Bruno Maresca, and Bruno Tota, illuminate topics such as ecology, evolution, life history, as well as physiology, biochemistry, and molecular biology. This work is of interest not only to specialists but also to anyone interested in fundamental and evolutionary biological questions. It provides valuable insights into the mechanisms of cold adaptation and stimulates discussion on adaptation to extreme environments.
