On animals and sound

From Orion: "When we ponder the perceptual adaptations of other animals, we typically do so through the lens of our own priorities. … Auditory 'noise' is not necessarily clutter; it can be rich in information and context, particularly for animals that live in the dark — in deep earthen warrens, within the haze of seawater, or under the cloak of night. For these, sound allows them to reach out and weave themselves into the fabric of their environment, sensing movements of predator and prey, and perceiving the boundaries of their surroundings."
