Giraffes are well adapted to a life in a savannah. They drink water when it is aivailable but can go weeks without it, they rely on morning dew and the water content of their food. Their very long necks are an adaption to feeding at high levels in the treetops. Their physical adaption, a long neck, does not only help them to graze but also helps them keep track of predators and it enables visual communication with other giraffe over several miles.
In the giraffe did not have a long neck it would be an easier pray for predators and it would not get as much food.
Similar to giraffes are elephants. They use long trunks to reach high tree-tops.
