There are seven bones in a giraffe's neck. A human neck has the same number of bones, though they are shorter. A male giraffe shows dominance by swinging its neck into the body of another giraffe.
Because of their lengthy necks, giraffes are able to feed off the leaves, fruits and flowers of tall trees. That reach is further extended by raising the head vertically upwards. Male giraffes can reach up to approximately 19 feet, which is about 3 feet higher than females can. A giraffe's foliage of choice is deciduous foliage during the rainy season and evergreen at other times.
