- Tarsier.
Dolgopyaty are primates with a height of only 9-16 cm and weighing only 80-150 grams, inhabiting the islands of Southeast Asia. Small size does not prevent the animal from being a predator at all. Moreover, tarsiers are the only primates in the world that feed only on food of animal origin.
- Chameleon.
Many people know that a chameleon can change color. So he disguises himself and shows his mood and demands to other lizards. Vision in these animals is also unusual - densely fused eyelids cover the entire eyeball, leaving only a small hole for the pupil.
- Dragonfly.
The organs of vision of the dragonfly are also unique and unusual. They occupy almost the entire head of an insect and can cover a space of 360 degrees.
Each eye of a dragonfly consists of 30,000 minute light-sensitive cells. In addition to two huge eyes, she has 3 more eyes. This special sight makes an insect a dangerous air predator, capable of reacting to any movement in a fraction of a second.
- A colossal squid is a mystery of the ocean.
This is the largest invertebrate animal known to scientists. He is also the owner of the biggest eyes among all the representatives of the animal world. The diameter of his eye can reach 30 cm, and the pupil - the size of a large apple. Vision in squid is just 100 percent even in dim light. This is very important for him, because these animals live at a depth of at least 2000 meters.
