 | | Because of their exceptional hearing capabilities, their echolocation sense, and the importance of sound in the underwater world, all dolphins were thought of as primarily auditory animals.; Vision was believed to be not particularly well developed, even in oceanic dolphins, and of secondary importance at best. |
 | | For example, as the dolphin swims on its side, the pupil of the downward looking eye, gazing into the dark, may be fully open, while the pupil of the upward looking eye, gazing toward the bright surface, may be tightly constricted. |
 | | Dolphins can attend to and interpret human gestures, follow the direction in which a human is pointing, monitor rapidly occurring visual symbols appearing on a television screen and report the occurrence of certain key symbols, and easily recognize the same objects across the senses of vision and echolocation. |
