2. Four eyed fish
A "four-eyed" fish swims along the surface with eyes appearing both in and out of the water. The fish does not actually have four eyes, but the eye is divided to allow the fish to see both above and below the waterline. A narrow band of epithelium divides the upper and lower halves of the eye.
3. Leaf tailed gecko
Leaf-tailed gecko, also known as flat-tailed gecko is reptile that belongs to the family Gekkonidae. There are more than 10 species of leaf-tailed gecko that are endemic for Madagascar and surrounding islands (they cannot be found anywhere else in the world).
Leaf-tailed gecko has large eyes without eyelids, sticky toes on the feet and long, broad and flat, leaf-like tail (hence the name "leaf-tailed").
4. Slow loris
Loris is a type of primate. They can be found in India, southeast Asian and Sri Lanka. Number of lorises dropped drastically in the last couple of years due to habitat loss and hunting (local people use them for religious and medical purposes or they sold them as pets).
Their eyes are very big and also have specific reflective layer (called tapetum lucidum) which provides excellent eyesight during the night.
Owls are birds from the order Strigiformes. Of all an owl's features, perhaps the most striking is its eyes. Large and forward facing, they may account for one to five percent of the owl's body weight, depending on species.
Kinkajous live in the tropical forests of Central and South America, where they spend most of their time in the trees.
They have elongated bodies with short legs, a rounded head with large eyes, a small muzzle, and round ears.
Dragonflies are classified into the insect order Odonata which also includes the physically smaller and slower-flying damselflies.
Their eyes are made up of thousands of ommatidia (telescope-shaped clusters of photoreceptor cells) that resemble a honeycomb. These collect light and signals that, when they are processed by the brain, can produce a clearer and less pixilated image than in other smaller-eyedinsects.
