It's World Giraffe Day. You may already know that the giraffe is the tallest mammal on earth, but did you know these other 5 facts...?
🦒 A giraffe's tongue can measure up to 20in long.
🦒 Just like human fingerprints no two giraffes have the same spot pattern.
🦒 Giraffes spend most of their lives standing up, they even give birth standing up, with calves falling up to 6 feet to the floor!
🦒 Giraffes don't need much sleep to function, typically only getting between 20 minutes - 2 hours of sleep a day!
🦒 Giraffes can run at speeds of up to 35mph over short distances!
🦒 NASA studied baby giraffes and the blood vessels in their legs to get inspiration for human space suits.
