EYES ARE A complicated part of our body.
They are our windows to the world but the human versions are different to many of the world’s other creatures. And they all differ from each other too, depending on their own needs.
In the February edition of National Geographic, Ed Yong examines the phenomenon. He shows – through wonderful photographs by David Liittschwager - how a creature’s environment contributes to the function, form and appearance of its eyes.
In the article, Inside the Eye: Nature’s Most Exquisite Creation, he tells us if we understand the structure of an animal’s eye, we have an idea of how the animal sees the world.
Check out these 10 amazing shots Liitschwager took to help prove the point.
The eye of a Cuban rock iguana (Cyclura nubile nubila) offers a window into a fundamental truth of evolution: Form follows necessity.
Four types of cone cells in this diurnal creature’s retina provide excellent daytime colour vision. A simpler third eye on top of the lizard’s head senses light and helps regulate body temperature.
