Behind the Lens of Animal Eyes

Jill Harness

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.
