We usually see flamingos in their vibrant pink color, but did you know they are born grey? The pink hue comes from the algae and shrimp food they eat, which is rich in beta-carotene. The more they eat, the brighter their feathers become.

Fun fact: Flamingos stand on one leg to save energy and avoid tiring all their muscles. It’s also easier for them to run away if a predator appears.

Did you know that polar bears aren’t white? Polar bears look white because their hair is actually made up of hollow, colorless tubes that reflect light. This helps them blend into their snowy surroundings and stay warm in the freezing Arctic temperatures.

Their skin under is black, which helps them absorb heat from the sun.

6. Honey Never Expires

If you find an old jar of honey in your pantry, don’t throw it away just yet! Honey never expires because of its high sugar content, low moisture content, and natural acidity. The oldest honey ever found was about 5,500 years old!

It may crystallize over time. Simply heating it up will return it to its liquid form.

7. A Chameleon’s Tongue is Twice as Long as Its Body

Kangaroos have strong hind legs and a unique hopping motion, but they can’t walk backward. Their muscular tails and large feet make it impossible for them to move in reverse. Their hopping is called saltation, and they use their tails for balance. Walking backward would probably cause them to stumble.

Cats are unique among mammals because they lack taste receptors for sweetness. This means they can’t taste sugary treats like we do. Their taste buds are more tuned to savory flavors, which is why they prefer meat.

Next time your cat frowns at your cookie, you’ll know why! They just don’t enjoy it as much as you do!

Maybe it doesn’t help with smartness, but it sure does come in handy for survival. They also have the largest eggs of any living bird species! Oh, and they also have three stomachs!
