The power of animal eyes
The strange features of the structure and shape of the eyes could make it easier for animals to observe predators or detect prey.
According to the National Museum of History, Smithsonian, USA, the giant squid is the species with the largest eyes in the world, with a diameter of up to 25 cm. The large eyes help the giant squid see clearly when in deep water. With this advantage, the giant squid can detect a sperm whale 120 meters away.
The Husky Sibir dog of Siberia, Russia, evolved eye color to adapt to the low light conditions in which they live. A husky's eyes are almond-shaped and usually have two white spots at the top, giving the impression that they have four eyes. A dog has two different eye colors or each eye can also have two colors.
Chameleons can rotate and focus their eyes in separate directions when looking at two different objects at the same time. This can help geckos get a 360 degree view of their body.
Ca escolar, a large fish that lives in the deep sea, has the ability to see from the bottom up. They use this special sight to wait for and capture passing prey.
Shrimp are one of the species with the most complex visual systems in the animal world. The researchers found that some shrimp species will gaze at their prey before attacking with a swift movement that can heat up a small body of water in front of them.
Most animals and even humans have round pupils. However, the eyes of some species such as goats, toads, octopuses... tend to be horizontal and rectangular with rounded corners. This helps them widen the field of view and easily detect enemies.
According to research by Dutch scientists, the eyes of some birds such as eagles (pictured) have small oil drops in front, which help them filter and direct in the direction of light when the eyes are exposed.
The eyes of some animals such as cats or raccoons can glow in the dark. This ability is explained by scientists because their eyes have a reflective surface, also known as the cell layer tapetum lucidum. The eyes of each species can glow in different colors.
The cuttlefish, a mollusk, is a species that has the ability to completelyạiresize the shape of its eyes according to what they see.
