We know what you’re thinking, what on earth is that?! It might look like a very foreign or strange planet, but that is actually a close-up of a llama’s eye!
The wavy patterns are called “iridic granules” and they act as horizontal filters. These filters limit glare and reduce eye strain in bright light – Kind of like a built-in pair of sunglasses! These iridic granules also tighten and close over the pupil to limit the amount of light received while still focusing.
Llamas, interestingly enough, have three eyelids, as well as other more common features of the eye such as a cornea, a sclera, an iris and pupil, a lens, a retina and an optic disk. Llamas have an oval-shaped pupil, like some other animal species, and due to their small head sizes, their eyes have a tendency to look quite large.
Caimans are very similar to alligators, and the both species share similarly-looking pupils! They are a smaller breed than most crocodiles and alligators, and are commonly found in Central and South America. Some species of Caiman are also found in southern Florida.
Caimans have long, thick, tapering tails and elongated snouts. Judging by this photograph, they also have very unique pupils. You may notice the zig-zag markings on they eye, as well as the typically greenish-yellow coloring. Caiman eyes have a layer called tapetum behind their retina, containing crystals that reflect light and make night vision possible.
Did you know that the caiman eye at night not only produces an ‘eyeshine’ but it’s also iridescent, which means the color changes with the angle of the light source? Neither did we! Guess that’s what makes the animal kingdom a never-ending surprise…
#3 Siberian Husky
The eyes of a Siberian Husky are ice-blue, dark blue, amber, or brown. In some individual dogs, one eye may be brown and the other blue, or pupils may even be a combination of both. Husky’s have almond-shaped eyes, and they are known for having the most beautiful eyes of all the different species of dogs.
The Siberian Husky originated in north-eastern Siberia, and this is why the species has such a thick coat of fur. Huskies were originally sent to Canada and Alaska as working dogs, however they soon began to be chosen as popular domestic pets because of their gentle, but resilient nature. We think looking into this pupil is like looking into a cracked frozen lake. Absolutely brilliant coloring!
You might think you know a lot about everyone’s favorite monkey, but just take a look at those Chimpanzee eyes – They’re magical! The two chimpanzee species are the closest living relatives to humans, and this is why their pupils look so similar to our own!
Chimpanzees certainly are clever, and they can even walk upright on two legs when carrying objects with their hands and arms. Chimpanzees have also learnt how to make tools and use them to collect food. The species use vocalizations, hand gestures, and facial expressions to interact with one another, and even so much as a glimpse with those astonishing eyes of theirs can communicate a whole message to other members of their group.
Although the pupil of a chimpanzee is quite similar to those of a human, you may notice the coloring to be slightly different than our usual brown, blue, grey and green.
#5 Albino Tiger Python
Did you know that the Albino Tiger Python is the world’s longest reptile species? They can grow up to around seven meters long – Yikes! This species is found predominantly in Southeast Asia.
As you can see, their pupil has an unusual marbled pattern and is very circular in shape. Although their light coloring may seem like a disadvantage, it actually works well to help them fit into their natural jungle environment. If you’re a little faint-hearted when it comes to snakes, then perhaps it’s best you don’t read the next bit! Albino Tiger Pythons have been known to cause quite a few human deaths. Although some accounts have not been proven, it is believed that this species of snake has swallowed human beings whole – Crazy!
