What do giraffes eat and drink

Giraffe are browsers and mainly eat leaves and buds on trees and shrubs. They will also eat herbs, climbers and vines, and prefer flowers and fruit when in season.

Giraffes live in habitats where the available food varies throughout the year. 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, female, baby giraffe 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. Male giraffes are also more inclined to wander into dense woodland, a habitat that females generally avoid.

Giraffes drink large quantities of water and as a result, they can spend long periods of time in dry, arid areas. When searching for more food they will venture into areas with denser foliage. The giraffe has tough lips to ensure there is no damage to their mouths when chewing at trees and twigs such as thorns.

Giraffes in captivity are generally fed on alfalfa hay and pellets, apples, carrots, bananas and browse (elm and alder are favourites).

Brain more powerful supercomputers

If the human brain is a computer, it can perform billions of calculations per second 38,000 and approximately 3,584 terabytes of storage memory. Meanwhile, one of the most powerful supercomputers in the world - BlueGene - have the ability to calculate 92,000 billion operations per second and only 8 terabytes of storage.

Upon receiving the information, the brain transmits information back through motor nerve cells, to your hand to pull it away from hot objects.
