Most giraffes rest while standing up, but every once in a while they can be found sleeping with their head resting back on their butts. This form of sleep usually only lasts for very short periods of no more than five minutes because it's an extremely exposed and vulnerable position for them to be in. Researchers in zoos have found that giraffes go into REM sleep when in this position.
Giraffes are the tallest mammals in the world. Even newborn giraffes are taller than most humans.

When a giraffe lowers its head to get a drink, there's a change in blood pressure. To protect their brains from this change, certain valves manage the flow of blood, constricting to stop the back-flow when their heads get too low. NASA has done research on the blood vessels in giraffe legs hoping to apply it to human space suits.
And is that a very photogenic zebra we spot, too? This picture definitely needs to be framed!

From Imgur user YourLocalImgurZookeeper: "I'm a giraffe keeper and Tebogo is the giraffe equivalent of a garbage disposal, stealing non-edible objects and crunching them up and eating them. He is the biggest character of our 11 giraffes. He is not one for personal space, especially when he spots one of his keepers. Come visit Tebogo and the 10 other giraffes at the Dallas Zoo."

Every once in a while male giraffes will take part in a ritualized style of fighting called 'necking' that helps them establish dominance. They swing their long necks to deliver powerful head-butts to one another and their reinforced skulls typically absorb most of the impact. Occasionally one of the giraffes will be knocked unconscious.
