Hang on- our exploration to the world of animal kingdom is almost ready! These animals have amazingly adapted with stunning eyes that could probably put you in awe! Among these impressive eyes, which is your prince charming?

Eagle


Image source
My eyes have impressed many animals on earth, including you humans. The shape of my eyes is different from yours, the back of my eyes are larger and flatter, and thus providing me an excellent vision.

Image source
Within my retina, there are many cone and concentrated rod cells that dispatch vision information to my brain for further interpretation. In the center of my fovea (focusing point on the retina), there are approximately million cones per millimetres (humans only have 200,000 cones per millimetre), which help me to see an object or prey clearly and sharply.

Image source
Aha, I forgot to tell you that I also have three eyelids, with the bottom eyelid being larger than the top one, and this explains why I always blink up instead of down.
Crocodile


Image source
You English people use a phrase ďcrying crocodile tearsĒ, which is wrong instead. To make it clear to you, I donít cry because I donít have tear ducts. But, well yes, my eyes can produce secretion (products of the lachrymal glands, and this proteinaceous fluid is secreted behind my third eyelid, or nictitating membrane) to both clean and lubricate the passage of the nictitating membrane across the surface of my eyes, while assisting to reduce bacterial growth.

Image source
The edge of my nictitating membrane is visible in the corner of my eyes when Iíve my eyes opened widely. Therefore, you may take me mistaken for crying as you can always see tears forming within my visualized nictitating membrane.
Stingray




Image source
Iíve a bad reputation due to the poisonous sting on my tail. Even though my tail is poisonous, I donít prefer to sting other animals with my tail. During the day, I prefer to bury my body leisurely beneath the sand. However, in the evening, Iíll pull my body out of the sand to hunt for food. I ďflyĒ almost like a bird in the sea.



YOU WELCOME FRIENDS....///

The Most Interesting Animals with Amazingly Remarkable Stunning Eyes





Hang on- our exploration to the world of animal kingdom is almost ready! These animals have amazingly adapted with stunning eyes that could probably put you in awe! Among these impressive eyes, which is your prince charming?


Image source
On top of my flat body, there sits my two attractive eyes, so even while resting beneath the sand, I still can see whatís happening around me. But sadly to say, my eyesight can be as poor as an adult old man. Even though my eyesight is extremely poor, Iím still proud of myself as Iím one of a reasonably intelligent animals dwelling in the sea.
Camel



Image source
How would you like me? Am I looking attractive to you? One day, while reading a note left by my ancestor million years ago, I came to realize that weíve long been awarded by humans as the Ship of the Desert. Hmmm, you know, I can go without water for a month in a desert, because I can drink up to 30 gallons of water at one time. Huh, surprising, right?

Image source
My eyes are large and are located on the sides of my head. Each of my eyes is protected by three eyelids. Two of my eyelids (the lower and upper eyelids) have curly, long eyelashes that help keep swirling dust and sand out of my eyes. The thick bushy eyebrows protect my eyes from the desert sun. I can see through in a sandstorm as Iíve a third thin eyelid.
Snail



Image source Image source
Hey, Iím not blind! I got eyes. Look carefully! My eyes are located on the tip of the tentacles but the sea snailís eyes are located at the base of the tentacles. Since Iíve two pairs of tentacles on my head, you wonít find my eyes on the shorter tentacles because my eyes are only found on the longer pair.
Panda

Buddy, donít you fall in [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]love
[/COLOR] with my eyes? Interesting though, my BLACK eyes may appear TOO BIG to you, but actually, they arenít my eyes. Theyíre black patches around my eyes. My REAL eyes are actually located inside the black patches, canít you see them? Though Iím grouped under a BEAR category, Iím not similar to most bears as theyíve round pupils. Instead, Iíve pupils that are cat-like vertical slits, and due to this reason, Chinese gave me a name of ďxióng māoĒ, or literally means ďlarge bear catĒ or ďbear catĒ.
Snake




Image source
Do you know why I always keep my eyes opening? The answer is that I donít have movable eyelids as like most lizards have which help them to periodically close to lubricate and protect their eyes. This is a good reason why I always stare at my prey. My eyes are protected by obvious scales instead. Theyíre protected by tough, immobile, transparent scales. Hey, my friend, tell you one secret. Do you know that rattle snake has elliptical pupils? But this is not a case in most non-venomous snakes, as their pupils are not round instead.
You may also see some of my species have a reddish brown ring around the left edge of their pupils. Some of them have green, orange, [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]gold[/COLOR][/COLOR], yellow or brown eyes. You may also fall in love with some of my species that have relatively beautiful grey, gold or blue eyes.

I use my eyes to detect movement of prey, but Iíve a problem to see a motionless prey or enemies. And Iíve poor eyesight towards objects located at 40 feet, but my vision improves, if the objects are at 10 to 15 feet. Our eyes are not used for detecting foods instead, as like rattle snake, their eyes are adapted for nocturnal searching while for garter snakes, their eyes are adapted for the use of daytime activity.

The Most Interesting Animals with Amazingly Remarkable Stunning Eyes



Hang on- our exploration to the world of animal kingdom is almost ready! These animals have amazingly adapted with stunning eyes that could probably put you in awe! Among these impressive eyes, which is your prince charming?

Gecko



Image source Image source


Iím a small, big head lizard with BIG eyes. At night, while hunting for prey, the vertically slit pupils of my huge globe-like eyes open widely to allow the maximum amount of light to enter, so that I can see clearly at night. However, during the day, my pupils close to a tiny slit. My eyes are protected by a thin transparent membrane, and to keep it clean and moisten I use my long sticky tongue to lick it.
Scallop

You probably donít know that Iíve eyes. A single of my species may have more than 100 gorgeous blue eyes or ďpeepersĒ. Even though weíre the most-eyes marine animals, we canít see because our eyes are virtually useless in terms of actual vision.


Image source
My eyes are tiny and theyíre abundant along the right and left valve mantle margins. Each of my eyes is very unique as theyíre functioned like a reflecting telescope that complete with a concave spherical mirror to bounce incoming light rays back to my image-forming retina with an angular resolution of around 2į. The crude image then is formed on light-sensitive cells located in the middle of my eyes. I donít have to worry if I lose my eye as I can always regenerate it.
Tarsier


Image source
Iím the worldís smallest known primates, but my eyes are enormous in comparison with my body size. HahaÖbecause of my adorable appearance, Iím sure that youíll fall in [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]love
[/COLOR] with me. Since my eyes are too LARGE, they cannot be turned around in my eye sockets. However, Iíve a special adaptation in my neck that allows me to rotate at 180 degrees.




Image source
Do you know how large my eyes are? They can be as big as the grapefruit-sized eyes in humans, and not only that, my eyes are the largest among the land mammals. The huge eyes with large pupils provide me very acute night vision to enable me to become an excellent night hunter.

The Most Interesting Animals with Amazingly Remarkable Stunning Eyes


Hang on- our exploration to the world of animal kingdom is almost ready! These animals have amazingly adapted with stunning eyes that could probably put you in awe! Among these impressive eyes, which is your prince charming?

Chameleon


Image source
Iíve the most striking eyes among the reptiles. Youíll observe that my lower and upper eyelids are joined together, leaving one large pinhole for my pupil to see through. Iíve an ability to roll or rotate each of my eyes to see two different objects from two different directions at the same time. This perfect visual ability gives me a 360 degree field of vision.
Chameleon says, ď Donít trick me! When one of my eyes is looking at you, the other eye of mine is looking back, so please donít play dirty trick on me.Ē (quoted from my previous article entitled animal magician)
Frog




Image source Image source
My eyesight is excellent. The protruding eyes on the side of my head help me to see in almost all directions and also to see well in dim light. So, next time, donít attempt to sneak up me as my bulging eyes can help me to see you in all different angles or directions without my head moving. Under the water, my eyes are protected by a nictitating membrane, which is an extra transparent eyelid.
You can always tell which of us is male or female. If you come across any of my species with their eardrums smaller than their eyes, theyíre female frogs. Male frogs have their eardrums as big as their eyes.

Image source
Take a look closely. When I shoot out my tongue, my eyes are always completely shut. This explains that why I canít see while striking at my targeted meal. My eyes also have a surprising feature that helps me in swallowing my prey. When Iím eating, my eyes sink through openings in the skull to help force the food down to my throat. Thatís why youíll always see my eyes blinking while eating.

Owl

Of all my external features, my eyes are the most striking one. My eyes are normally large which may take one to five percent of my body weight, but this will depend very much on species. As for your information, my friend, Great Horned Owl, does have eyes as large as a manís. Since Iíve a wide range of spectacular vision (seeing an object with both eyes), Iím able to see objects in 3 dimensions (height, depth, and width), giving me an ability to judge distances accurately in a similar fashion as humans do.

Image source
In low or dim light, my eyes are large to help gather more light, and thus providing me extraordinary night vision. My eyes are developed pretty well since I was born, and theyíre held in place by bony structures in the skull called Sclerotic rings. Due to a reason that I donít have eye balls and my eyes are fixed in the sockets, I canít move or roll my eyes. Thatís why I always look STRAIGHT ahead! To look on another object, Iíll have to swivel my head, and I can do this movement in an astonishing speed.
There is abundance of rod-shaped, light-sensitive cells in my retina, which are sensitive to movement and light. I possess only few of cone-shaped cells, and thus I can only see in limited monochrome or color.

Dragonfly


Image source Image source
Iím an amazing animal and have long been known as ďsnake doctorsĒ. Iíve a pair of large multifaceted compound eyes which occupy almost all of my head. Each of my compound eyes has up to 30,000 individual lenses called ommatidia (a separate light-sensing organ), and thus giving me a 360 degrees perfect field of vision.
Iguana




Image source
My eyes may make you feeling scary, but do you know that my eyes can detect ultraviolet wavelengths of light that you humans canít detect. This is particularly useful when Iím basking my body, while allowing me to insure sufficient vitamin production in my skin for a proper mineral absorption. My sensitivity to wavelengths helps me to find my favorable ďtidbitĒ (such as flowers and fruits). Furthermore, my excellent vision helps me exploring safely through the maze of branches in the forest canopy or the crowded forests, and Iím capable enough to detect shapes, shadows, [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]color
[/COLOR] and movements at astonishingly long distances.

Image source
Donít disturb me, if you happen to see that I dilate and contract my large pupils in succession, as though an effect of a camera shutter opening and closing, which you human calls ďeye flashingĒ. At this moment, Iím feeling agitated or excited. While resting, my eyelids meet halfway up my eyeballs. Again, donít disturb my good deep sleep, when you see my lower eyelids moving up to cover my whole eyes.
Moth

Like other adult insects, Iíve compound eyes that are made up of many corneas or hexagonal lens called ommatidia, giving me a broader range of vision, and thus I see an object or prey in the back of my head. Nevertheless, thereís a shortcoming for my compound eyes as I see an image as tiny blurs of light.




Image source
These ďpeepersĒ (lenses) help me to focus incoming light onto a rhabdome (or retina in humans). Later, an optic nerve delivers impulse to my brain for further interpretation. Do you know what so special about me? I can see ultraviolet rays that are invisible to you humans.
Our babies can hardly see as theyíve simple eyes called oceilli which only enable them to distinguish dark from light. As their eyes are composed mainly by photoreceptors (light-sensitive cells) and pigments, the image cannot be formed properly. Therefore, our babies canít see well as the adult moths.

Jumping Spider


Image source
Donít humiliate at my small body! Donít you know that Iím a good jumping champion? In fact, I can leap 10 to 40 times of my body length to avoid becoming prey or to pounce on prey.

Image source
My eyes may appeal to you as alienís eyes, but Iím actually proud of my excellent vision. Like other spiders, Iíve eight eyes.

Image source
Look closely! Iíve four eyes on my face with the enormous pair located in the center, which makes you seeing me as an alien. My remaining small eyes are located at the dorsal surface of the cephalothorax. Though my field of vision is narrowed to 2-5 degrees, my principle eyes have pretty high resolution, which is at 11 min. visual angle. Since Iíve a sharp vision, I can see my prey anywhere from 30 to 40 cm away.
Cat


Iím not boasting. My nocturnal vision is by far more superior to you human. My total vision is at 280 degrees, which is wider than you human who only can reach to a total vision of 220 degrees. Yup..yup.., my total vision is even broader than the dogs lolÖ I can see well than you at twilight. In bright light, my eyes shrink to a mere slit or narrow to a vertical slit, while in dim light, my eyes open widely to allow a maximum of illumination.

Image source
My [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]baby
[/COLOR] (kitten) goes blind while they were born because they canít open their eyes until they reach an age of seven to ten. Our visions are significantly weaker than human in the first three months. We canít see many colors as humans do, because we can only distinguish different shades of greenish and blue yellow. The colors of red and orange appear white to us.

Image source
Watch me! When my pupils dilate, that means Iím angry or Iím sexually aroused; and when I blink my eyes, that means Iím being stroked.
Robber Fly

My grandma told me that our species is one of the 4,000 species fly in the family Asilidae. Human called us assassin fly. But, strange though, human always mistaken us for bumblebee. Wanna pay me a visit? Iíve many ďbranch officesĒ in grasslands throughout the world. Iím an impressive predator that [COLOR=#7FAB00 ! important][COLOR=#7FAB00 ! important]loves[/COLOR][/COLOR] sun bathing my tender body among the dry open areas which include pastures, sandy places, and etc.

Image source
Iíve an excellent vision that enables me to determine the distance and speed of objects or prey moving in front of me. When I spot something that is food, Iíll fly close to investigate my targeted meal. My head is very large with two large compound eyes, each containing several thousand separate lenses that provide me with a remarkable vision, particularly while spotting a small insect at a considerable distance.
