Bats do it

Assuming that one’s senses shape one’s experience, a bat with both eyes and echolocation, a goat with its rectangular pupils, a spider with its eight eyes, a butterfly with its compound eyes, and a scallop with a hundred little bright blue eyes experience the world differently than the way we do. Further, different combinations of sensory inputs matter. A spider’s eyesight is not very acute, but it can rely on touch, vibration, and taste as well as on its vision.
