Humans view the world from a different perspective but have you ever wondered how different organisms in the animal kingdom view their world. According to psychology, everyone has a different experience of color and perceptions. But have you ever wondered how the view would change if they are of different sized and shaped eyes? The different shapes and locations of the eyes of every organism have been created by nature to aid its existence in nature. For example, herbivores have a horizontal pupil that creates a panoramic view for them. It is because they can see the hurdles and obstacles in their way and the predator is coming towards them. Vertical pupils are present in nocturnal predators which answer is there a vision during the night. There are different and weird types of eyes in the animal kingdom.
Birds are probably the cutest members of the animal kingdom and have sweet little eyes. They can see much as compared to humans, the four to six cones allow them to have a monochromatic vision. They can also perceive non-colored motion. Humans on the other hand have four cones that make them see colors of three peak wavelengths. The protein in their eyes also allows them to visualize the magnetic field. It allows them to fly high over places, migratory birds are thought to have the best vision and their eyes are extremely sensitive to blue light. There are some interesting facts about the perception of the magnetic field that the birds can see the magnetic field due to their dependence on blue light. It means that their sense is vision-dependent.
Mantis shrimps are considered to be members of the animal kingdom that have the most complex eyes. It mostly dwells at the bottom of the sea in rocks. They can see almost everything that humans and birds can’t. They have sixteen photoreceptors that can catch the light of every wavelength. They possess five different ultraviolet frequency bands and can see ultraviolet light as well as polarized light. They have so many complicated visual organs that we can not exactly determine what they see. The eyes of Mantis are located on a stalk and can move independently. Their eyes can see a detailed perception of everything, they can even visualize cancer cells even before the symptoms show.
Chitons preside in the depth of water bodies on the rocks and they are protected by thick armor. They have eyes that can move out of the shell and peep around to see predators. Their eyes also made them aware of the day and night cycle. They can resolve images by simple eyes and numerous sensory organs. They have an aragonite lens which is covered by a cornea and a type of retina. However, their visionary information is not perceived by the brain. But studying these interesting creatures in detail can help us understand how the vision evolved on Earth. They give us an idea of how their ancestors developed their vision.
