Invertebrate Photoreceptors

Invertebrate Photoreceptors: A Comparative Analysis covers the structure and pigment chemistry of invertebrate photoreceptors. The book discusses the photobehavior and photoreceptor systems of invertebrate animals; the protozoan photoreceptor; and the compound eye. The text also describes the crustacean and mollusc eyes; the vertebrate retinal photoreceptors; and the invertebrate eye and its visual pigments. The book concludes with discussions on primitive photoreceptors; spectral sensitivity, pigments, and color vision; and polarized light analysis. Biologists and people involved in the study of invertebrate photobiology will find the text invaluable.
