Color Change Mechanisms of Cold-Blooded Vertebrates focuses on color change in vertebrates and its relation to endocrine control. The book first tackles physiological color changes in amphibians, elasmobranchs, teleosts, and cyclostomes. Topics include description of responses, nonvisual response, criticisms of the two-hormone hypothesis as applied to amphibians and elasmobranchs, and summary of teleost color change mechanisms. The publication then elaborates on physiological color changes in reptiles and biological assay of melanin-dispersing hormones, as well as generalities about reptilian color change, general statement on biological assay, and theoretical considerations. The manuscript ponders on the chemistry of melanin-dispersing hormones, mechanism of the melanophore, and actions of melanin-dispersing hormones on functions other than color change. Discussions focus on glandular origin of melanin-dispersing hormones, energy sources for melanin movement, and metabolism. The text is highly recommended for readers interested in color change in vertebrates.
