Abstract
Twenty-five species belonging to 12 families were studied. Their habitats ranged from coastal, pelagic zones to depths of about 300 meters. Corresponding variations in retinal structure, intraocular circulation, and activity were observed. Based on these, three categories have been established. The first includes species with poorly developed retinae, very sparse circulation, and no activity, inhabiting deeper waters; the third comprises active species with well-developed retinae and good blood supply, inhabiting coastal or pelagic zones. The second category groups the intermediate forms. Variations in retinal structure and circulation and the relationship between the two aspects are discussed.
