• Sommario/riassunto: Animal Eyes provides a comparative account of all known types of eye in the animal. kingdom, outlining their structure and function with an emphasis on the nature of. the optical systems and the physical principles involved in image formation. A. universal theme throughout the book is the evolution and taxonomic distribution of. each type of eye, and the roles of different eye types in the behaviour and ecology. of the animals that possess them. In comparing the specificcapabilities of eyes, it. considers the factors that lead to good resolution of detail and the ability to. function under a w
