One of the most inspiring aspects of the Photo of the Day series is seeing the world through your eyes. Such is the case with this incredible sunrise that photographer Tony Carado captured.

You've probably heard that raccoons wash their food before they eat but did you know that... it's not true? We debunked the myth in this photo of the day, and discussed how it's really all about a raccoon trying to "see" its food through the sensitive pads of its paws. "Rolling their catch around in their paws lets them know just what they're about to eat. Same goes for when there is no water around at all. While the action looks like washing, it's more about getting a good enough grip on their catch and figuring out the best way to get their meal into their mouth."

We adore watching hummingbirds flit from flower to flower, but we rarely stop to think about the power and anatomical prowess with which they do it.
