Giraffes, with their long necks and spotted patterns, are among the most iconic animals of the African savannah. Their unique physique is not just for show; it plays a crucial role in their diet and survival. Let's delve into the fascinating world of giraffe nutrition and discover what sustains these gentle giants.
Key Takeaways:
- Giraffes primarily feed on the leaves, fruits, and flowers of trees and shrubs.
- They have a particular fondness for Acacia trees, which provide them with most of their nutrients.
- Giraffes use their long tongues to strip leaves from branches, avoiding thorns.
- They also consume grass, fruits, and seeds when available.
- Water is not a daily necessity for giraffes, but they drink when they can.
The Primary Diet: Browsing on Trees and Shrubs
Acacia Trees: A Giraffe's Favorite
Giraffes have a particular fondness for the Acacia tree. These trees are abundant in the African savannah and provide a rich source of nutrients. Giraffes use their long, prehensile tongues, which can reach up to 45 cm in length, to strip the leaves off branches. Their tongues are tough and can navigate around the sharp thorns of the Acacia tree.

Other Trees and Shrubs
While Acacia trees are a staple in their diet, giraffes also feed on the leaves, fruits, and flowers of other trees and shrubs available in their habitat. Some of these include the Commiphora (myrrh tree), Combretum (bushwillow), and Terminalia trees.
Grass, Fruits, and Seeds: Occasional Delights
Though giraffes are primarily browsers, they do graze on grass when it's available, especially during the rainy season when fresh shoots sprout. They also enjoy munching on fruits and seeds when they come across them. However, these are not a significant part of their diet and are more of an occasional treat.

Water: Not a Daily Necessity
Contrary to what many might think, giraffes do not need to drink water daily. They get most of their water from the plants they eat. However, when water is available, they drink large quantities at once. Their long necks are not a hindrance when drinking; instead, they spread their front legs apart and bend down to reach the water.
Giraffes' Unique Digestive System
Giraffes have a four-chambered stomach, similar to other ruminants. This allows them to ferment the food they consume, extracting maximum nutrients. They often regurgitate their food, chewing it as cud before swallowing it again for further digestion.
Frequently Asked Questions
How Do Giraffes Navigate the Thorny Acacia Tree?
Giraffes have a clear preference for the leaves of the Acacia tree. While these trees have long thorns that deter most animals, giraffes have evolved to manage this challenge. Their long tongues, measuring between 18 to 20 inches, can maneuver around these thorns. Moreover, they have a thick, sticky saliva that protects them from any thorns they might accidentally swallow. When in season, giraffes also consume the flowers of the Acacia tree, which contain more tannin but also offer twice the protein.

Do Giraffes Drink Water Regularly?
Acacia leaves provide a good amount of hydration, so giraffes don't need to drink water daily. They can even go several days without drinking. However, when they do drink, they can consume up to 10 gallons in one go. In the wild, giraffes often drink in groups, taking turns to keep an eye out for predators. Their unique physique makes bending down to drink a challenge, making them vulnerable during these moments.
Why Do Giraffes Prefer Eating from Trees Over Grass?
While more than 90% of a giraffe's diet in the wild consists of tree leaves, they do occasionally graze on grasses. However, reaching the ground to graze or drink can be awkward for these tall animals. They need to spread their legs and bend at the knee, a position that makes them vulnerable to predators. This might explain their preference for food sources that are at shoulder level or above. It's rare to see a solitary giraffe grazing; they usually do this in groups for safety.

How Do Giraffes Digest Their Food?
Giraffes, like cows, are ruminants, meaning they have a four-chambered stomach to aid in digestion. They chew and swallow leaves, which form a ball in their stomach. This is regurgitated as cud, which they chew again before swallowing for further digestion. Giraffes tend to eat more during the cooler parts of the day, spending the hotter hours ruminating.
What About Baby Giraffes?
A baby giraffe, or calf, begins life with a dramatic 5-foot drop to the ground during birth. Within an hour, it's up and nursing. While they start sampling vegetation within their first week, they continue to nurse until they are six to nine months old. After this, they transition to a typical giraffe diet.
