This week's Animal Oddities post is all about animal eyes. Recently, Treehugger did a story on the subject and it made me realize how strange-looking the eyes of animals are, and how different they can be from one species to the next.
Eyes, of course, are the parts of an animal's body that it uses to see its surroundings, and they come in many different shapes, sizes and abilities. Some animals see in full color, some only in black and white. Some animals see ultraviolet parts of the spectrum not visible to humans. Some animals have eyes that face forward and provide binocular vision and depth perception, while others have eyes on the sides of their heads to see what's behind them as well as what's in front of them (not surprisingly, predatory animals typically have front-facing eyes while prey species have side-facing eyes). Amphibious and aquatic species often have eyes on the top of their heads, sometimes even on stalks, to allow them to peer beyond the water's surface without exposing their whole bodies. Some animals have jet black eyes, while others have brightly colored ones. Some animals have round pupils, others have slit-shaped ones, and some even have rectangular pupils. Some animals even use their eyes to startle predators or mimic the eyes of larger animals with completely different parts of their bodies.
No matter what kind of eyes an animal has, there is something more to them than just tools providing the sense of sight. The old proverb says that the eyes are the windows to the soul, and it's true that you can't look into the stunning eyes of an animal and not feel some kind of connection to that creature.
