Most predators have a property that enables them to see at night well and catch prey. The reason for the glowing eyes of predators is almost certainly the effect of adrenaline on them, but an animal like the reindeer does not have such eyes, but its color changes with time This is what we will explain to you.
+ Reindeer:
Reindeer is a predominantly animal living in polar regions such as Russia, Mongolia, northern China, the United States of America. In many countries of the world, male reindeer is larger than females. The animal weighs from 60 to 170 kilos and has two horns and the domestic reindeer is shorter and heavier. Of the terrestrial ring. This animal has a layer of grease that helps it adapt to heat and cold. The animal feeds on algae, bird eggs and fungus. The breeding season starts from September to November, and the males fight against the female. Food in this period of time .
+ Polar Reindeer and change the color of his eyes:
- The polar reindeer is born at the beginning of his life. He can not see and live his life for a few months in the dark. In the summer, the eyes of the animal are golden in color and turn in winter to dark blue. Such as horses, cats or other animals, but it is because the reindeer lives for a period of time in the total darkness that hovers in the eye during the winter, and this is for two months and this causes the increase of liquid pressure in the eye, and leads to fusion Collagen fibers are present within the membrane This results in a change in the optical wavelength reflected by the eyes.
- This membrane reverses light in the direction of the retina, such as the mirror and this allows the eye the opportunity to exploit the colors available in the natural color of the stars and the moon and street lights and the greater the source of light in intensity increased with the glow in the eyes of those animals, in winter reflect the color of blue reindeer eyes light by 50% less than summer, due to the seasonal change in the membrane of the eye and this makes you think that the ability of reindeer in winter is weak.
- Scientists have recently discovered that the compact design in the eyes of the reindeer allows the diffusion of light into other eye-catching directions that make it visible in the winter. This is done through the reflected light that protects it from the dark nights of darkness. Scientists have discovered that the blue eyes of the reindeer In winter it is stronger than other predatory animals.
- The scientists did not prove the functional relationship between the fluid in the eyes of the reindeer and the color of the eyes and their ability to reflect the light in addition to many of the visual benefits that indicate the strong relationship of the ability of these eyes, and in another test conducted on a group of reindeer was observed The reindeer's eyes have changed to green, and this change seems to be unsuitable for lighting in the brightly lit summer so that its color is golden in contrast to its blue eyes in the winter.
