1.A giraffe can clean its ears with its 21-inch tongue.
2.Giraffes are difficult and dangerous prey. The giraffe defends itself with a powerful kick. A single well-placed kick from an adult giraffe can shatter a lion's skull or break its spine.
3.The pace of the giraffe is an amble, though when pursued it can run extremely fast, up to 55 km/h.
4.The blood vessels in the lower legs are under great pressure (because of the weight of fluid pressing down on them). In other animals such pressure would force the blood out through the capillary walls; giraffes, however, have a very tight sheath of thick skin over their lower limbs which maintains high extravascular pressure in the same way as a pilot's g-suit.
5.The giraffe has one of the shortest sleep requirements of any mammal, which is between ten minutes and two hours in a 24-hour period, averaging 1.9 hours per day.
6.Courting males will emit loud coughs. Recent research has shown evidence that the animal communicates at an infrasound level.
