Studying the specialized eye structures of various creatures has often provided scientists with the necessary clue to their control or capture. By keeping the practical applications of the study of animal vision to the fore, the author has prepared an excellent supplementary book for biology students that will engage the attention of potential hunters and fishermen as well as those who have an appetite for the odd fact. Marine laboratories must find a workable shark repellent -- the answer may lie in an agent that clouds shark vision. Various pests of the insect world can be controlled by their response to color. The presence of a third eyelid and binocular vision is the reason for the mid-air hunting feats of birds of prey. The results of these animal vision experiments carried on all over the world in laboratories or from on-the-spot observation blinds have been skillfully gathered-in a text that answers many questions about the trappers, the stalkers and the camouflagers of the animal world. The methods of experiment are detailed and the questions yet to be answered are explored.
