✦ Synopsis

The aerial visual field of aquatic animals living near the water surface is distorted by refraction. The imaging of aerial objects by one or two submerged eyes is studied. The aerial binocular image field is determined for pairs of submerged eyes in horizonal and vertical planes. These two image spaces have significantly different structures. Aquatic animals have to correct for refraction, adapting themselves to the former aerial image field in order to recognize aerial predators or to capture such prey. The other aerial image space is only of theoretical interest.
