Their long necks help giraffes eat leaves from tall trees, typically acacia trees. If they need to, giraffes can go for several days without water. Instead of drinking, giraffes stay hydrated by the moisture from leaves.

 During the dry season, giraffes eat evergreen leaves, however, once the rainy season begins, they switch to new leaves and stems that sprout on deciduous trees. Also, twigs and branches are pulled into the mouth of the giraffe with their long and dextrous tongues. In the wild giraffes can eat up to 66 kilograms of food daily.

When there is a choice, male and female giraffes feed in different ways. Males concentrate on leaves from the highest branches, while the females arch their necks to eat closer to the ground. Because of this characteristic behaviour, a giraffe can be identified as either male or female from a long distance away simply by its stance while eating.
