Animals are endlessly entertaining, and the more you learn about them, the more amazing they get. Here are seven quirky facts from the animal kingdom.
1. Cows Have Best Friends: Studies have found cows show lower stress levels when they're with a preferred companion.
2. A Group of Flamingos Is Called a "Flamboyance": Fitting, right? And they're pink because of the pigments in the shrimp and algae they eat.
3. Koalas Have Fingerprints Almost Like Ours: Koala prints are so similar to human prints that they can be hard to tell apart, even under a microscope.
4. Cats Spend Up to Two-Thirds of Their Lives Sleeping: That's roughly 12 to 16 hours a day. Living the dream.
5. Dogs' Noses Are as Unique as Fingerprints: The pattern of ridges on every dog's nose is one of a kind.
6. Crows Can Recognize Human Faces: Research has shown crows remember people who've treated them poorly, and can even "tell" other crows about them.
7. Hummingbirds Can Fly Backwards: They're the only birds that can, thanks to wings that rotate in a figure-eight pattern.
