=== Perception ===
Animals process information from eyes, ears, and other sensory organs to perceive the environment.  Perceptual processes have been studied in many species, with results that are often similar to those in humans. Equally interesting are those perceptual processes that differ from, or go beyond those found in humans, such as [[Animal echolocation|echolocation]] in bats and dolphins, motion detection by [[Lateral line|skin receptors]] in fish, and extraordinary visual acuity, motion sensitivity and ability to see ultraviolet light in some [[Bird vision|birds]].<ref>{{cite book | vauthors = Stebbins WC, Berkley MA | date = 1990 | title = Comparative Perception, Vol. I, Basic Mechanisms; Vol. II, Complex Signals | location = New York | publisher = Wiley}}</ref>
