Maybe you know someone, or have at least seen enough epic photos of David Bowie to be somewhat familiar with heterochromia. Never heard of it? Well, it’s the scientific term for two different colored eyes!

It occurs more commonly for animals than people, which means there are thousands, nay, hundreds of thousands of beautiful animals are somewhere out there running around with their stunning eyes sparkling in the sunlight.

And thanks to the good people of the internet, those photos have been shared and we’ve rounded up the best ones here. Enjoy!
