Giraffes are the tallest standing land animals on earth.
Because they stand so high, giraffes have specially developed valves in their vascular system that ensures a good blood supply to their heads. They are vegetarians, eating the leaves of acacia trees, which they pluck with their 18 inch, purple tongues. They live across wide ranges of prairies and grasslands of sub-Sahara Africa. Giraffes actually have three skin covered horns on their heads, two prominent ones and a smaller, central horn between their eyes. Although their horns can be dangerous weapons, male giraffes usually use them when fighting over females.
