Sound is an incredible sense, and there are many in the animal kingdom that use this sense as a means of survival. Sound waves are produced by movement and there are some animals that have evolved organs to detect those sound waves in the air or water to perceive movements in their environment. This can be used to find prey, predators, and mates. These are some of the animals that have mastered the sense of hearing: frogs, owls, whales, giraffes, cats and rodents.
