Summary
Highlights
Horses have a blind spot directly in front of their faces due to eye placement and perceive a limited spectrum of colors, mainly greens, yellows, and blues.
Fish have ultraviolet receptors and spherical lenses, providing nearly 360-degree vision. While they can see many colors, red is difficult to discern underwater. Deep-sea fish can see in the dark.
Sharks cannot distinguish colors but have much clearer underwater vision than humans.
Birds can see ultraviolet light, aiding in species differentiation and navigation. Falcons and eagles demonstrate incredible focusing ability, spotting small prey from a mile away. Pigeons have a 340-degree field of vision and vision twice as good as humans.
Flies have thousands of receptors, giving them a broad view, and perceive everything in slow motion. They also see ultraviolet light for communication. Bees cannot see red, perceiving it as dark blue.
Rats cannot see red, and their eyes move independently, causing them to see everything doubled.
Cats cannot see red or green but possess excellent night vision, seeing six times better than humans in low light, and perceive brown, yellow, and blue hues.
Dogs cannot see red or orange but excel at seeing blue and violet, and can differentiate 40 shades of gray.
Frogs are particular eaters, only reacting to moving food. They also disregard unmoving objects or shadows not deemed important.
Chameleons have eyes that move independently, allowing them to see in all directions and perceive two different images simultaneously.
Snakes possess infrared-sensitive receptors in their snouts, allowing them to detect the radiated heat of warm-blooded mammals.
Cows struggle with color perception, unable to see red and only discerning variations of blue and green. They have near-panoramic vision but a blind spot directly behind them.
