The normally majestic looking giraffe appears quiet out of ordinary when it requires a drink. Giraffe can go long periods of time without drinking, which is probably a good thing because it is so awkward for them to bend over.  Physiologically, giraffe have unique anatomical differences in their blood vessels to allow them to lower their heads from a height of approximately 15 feet above ground to below ground level without fainting either when drinking or when they quickly raise their heads back up to normal position. Giraffe also have exceptionally long, dark tongues (up to 17 inches) that are incredibly tough.  Both males and females have horns covered in skin. When the males fight for dominance or a mate they stand parallel with each other, swing their head and necks outward and down until they collide together around chest high.  In this photo the bird in flight is an oxpecker that couldn’t hold on when the giraffe lowered it’s head. It quickly flew back onto the giraffe’s neck and a few minutes later was inside the giraffe’s ear picking out insects.
