Behind the Lens of Animal Eyes

Original image

Have you ever wondered why a goat has square pupils, or how bugs can see through their strange compound eyes? A recent article I wrote for Environmental Graffiti answers these questions and more by sharing the science behind 10 fascinating types of animal eyes.

The facts are pretty interesting. Hippos, for example, have a thing layer of membrane to protect their eyes from debris under the water. Nocturnal geckos can close their long, zig-zagged pupils to let in all but the tiniest bit of light during a bright day.

Even if you don't care about the science, the article also has plenty of great photos of animal eyes that are sure to pique your interest.

It’s Superman’s worst nightmare: the complete disappearance of the Sun from our perch on Earth. For non-Kryptonians, it’s a rare and awesome chance to see a unique spectacle that hasn’t happened for 99 years. Multitudes gathered Monday to observe the solar eclipse, a complete obstruction of the sun’s rays by the moon in an epic galactic photo-bombing. Here’s how stargazers across the country greeted the astronomy event.
