Giraffes are the world's tallest land animals, with a long neck and legs, a small hump on their back, and a spotted pattern similar to that of a leopard. They are herbivores and have a plant-based diet, feeding on leaves from trees and shrubs, adapting their diet based on availability and nutritional needs. They also eat herbs, climbers, vines, flowers, fruits, and occasionally grass. They have a long, sticky, dexterous tongue that helps them reach high-up food, and they lack upper front teeth, which helps them chew and rip leaves off branches.

How giraffes eat
Giraffes are herbivores and have a plant-based diet. They are browsers, not grazers, which means they mostly eat leaves and shoots from trees and shrubs, rather than grass and low vegetation. They also eat herbs, climbers, vines, flowers, fruits, twigs, and seeds. Their favourite food is the leaves of the acacia tree, but they also like the mimosa tree and wild apricot trees. In fact, giraffes can eat up to 85% of new acacia shoots.
Giraffes have a long, prehensile, sticky tongue that helps them to reach leaves high up in trees. They also have a ridged roof in their mouth, which helps them to feed on a variety of leaves and shoots. They do not chew their food very much when they first eat it, instead swallowing it quickly and partially digesting it, before regurgitating it to be chewed again later. This is called 'chewing cud' and is common in ruminants. They have a four-chambered stomach, which allows them to digest their food in stages and extract as much nutrition as possible from the vegetation they eat.
Giraffes spend a lot of time eating—up to 18 hours a day—and they eat a lot, too: between 1.6% and 2.1% of their body weight per day, or over 75 pounds of food. They are able to reach food that other animals cannot, due to their height and long necks. Male giraffes can feed at higher levels than females, as they are taller, but both genders reach near-vertical positions to access their preferred food.
Giraffes adapt their diet according to the availability of food and the season. In the dry season, when green vegetation is scarce, they may eat more dried-out plants, including twigs and bark. In the rainy season, they eat mostly deciduous species, and in the dry season, they eat more evergreen species. They also get most of the water they need from the plants they eat, only drinking water every few days. When they do drink, they must put themselves in a vulnerable position to reach the water, so one herd member usually stays on guard.

What they eat
Giraffes are herbivores with a plant-based diet. They are browsers, not grazers, meaning they eat leaves and shoots from trees and shrubs, rather than grass and low vegetation. Their diet includes more than 100 plants, but it usually consists of only a few species of trees and woody bushes.
Giraffes predominantly eat the leaves and shoots of trees, such as the acacia tree, which is favoured in all locations. They also eat the leaves and shoots of mimosa and wild apricot trees. They will also consume flowers, bark, pods, seeds, and twigs. In most areas, Vachellia or Senegalia (formerly known as Acacia) leaves and shoots make up the majority of their diet.
Giraffes have a four-chambered, or multi-chambered, stomach, which allows them to digest their food in stages. They swallow the leaves first, then regurgitate them back up the throat to be chewed again. This is known as "chewing cud". They then swallow the leaves again, and they are sent to the four compartments of the stomach for digestion. This process helps them extract as much nutrition as possible from the vegetation they consume.
Giraffes also eat some fruits, herbs, climbers, vines, and flowers when in season. They rarely eat grass. They can obtain all the water they need from the plants they consume, but they do drink water every few days, up to 38 litres at a time.
Giraffes spend a large part of their day feeding—up to 75% of their day during certain times of the year. They spend around 18 hours a day finding food and can eat over 75 pounds of food a day. They eat between 1.6% and 2.1% of their body weight per day.
When nutrients are scarce, giraffes will eat the bones of dead animals, such as buffalo, to obtain minerals like phosphorous and calcium. This is known as osteophagia. They will chew the bones to extract the nutrients and then spit them out.

How much they eat
Giraffes spend around 18 hours a day finding food, and they eat between 1.6% and 2.1% of their body weight per day, which is over 75 pounds of food. They have a four-chambered, multi-compartmentalised stomach that allows them to digest their food in stages. They swallow the leaves first, then regurgitate them back up the throat to be chewed again before they are sent to the stomach for digestion. This complex process helps them extract as much nutritional value as possible from the tough vegetation they consume.
Giraffes are the tallest land animals, and their long necks help them reach high-up food. They also have long, dexterous tongues that can reach food in hard-to-access places. Their tongues are dark purple to protect them from the sun, and they are thick to protect them from thorns. They lack upper front teeth, which helps them chew and rip leaves off branches.
Giraffes are herbivores, and their diet consists of leaves and buds from trees and shrubs, herbs, climbers, vines, flowers, and fruits. They also eat the bones of other animals to get nutrients like calcium and phosphorus. They adapt their diet to the available food species in their specific region, including deciduous trees, shrubs, vines, and evergreen species near water sources during different seasons.
During the dry season, when green vegetation is scarce, giraffes may consume more dried-out plants, including twigs and bark, that other animals typically avoid. In the wet season, they obtain most or all of their water from consuming leaves and dew, but in the dry season, they must drink at least every three days, up to 38 liters (10 gallons) at a time.

Where they get their water
Giraffes are the tallest land animals, and their height means they must adjust their legs to reach the ground to drink water. They are vulnerable to attacks from crocodiles when drinking from a pond or river. To avoid this, they tend to drink water only every few days, and they get most of the water they need from the plants they eat. In the wet season, they obtain most or all of their water from leaves and dew. In the dry season, they drink at least every three days, consuming up to 38 litres (10 gallons) at a time.
Giraffes are herbivores, and their diet includes more than 100 plants, although it usually consists mainly of a few species of trees and woody bushes. They favour the leaves of the acacia tree, which are high in protein, water, and calcium. They also eat the leaves and shoots of mimosa and wild apricot trees. They adapt their diet to the available food species in their specific region, including deciduous trees, shrubs, vines, and evergreen species near water sources during different seasons.
Giraffes are browsers, and they use their long, dexterous tongues to feed on leaves. They also lack upper front teeth, which helps them to chew and rip leaves off branches. Their height allows them to reach high foliage, and they can extend their heads to a completely vertical angle to increase their reach. Male giraffes can feed at higher levels due to their longer necks.

How their diet affects their environment
Giraffes are the tallest land animals, with necks that are 6 feet (1.8 meters) long. Their height and long tongues enable them to feed on leaves and shoots that other animals cannot reach. Their diet consists of leaves, twigs, buds, branches, and seeds from trees and shrubs, as well as herbs, climbers, vines, flowers, and fruits when in season. They also occasionally eat grass and bones from dead animals to obtain nutrients such as calcium and phosphorus.
Giraffes are herbivores and are considered browsers, not grazers, meaning they mostly consume higher vegetation. They are known to favour the leaves of the acacia tree, which is adapted to defend against giraffe browsing by increasing tannin production within its leaves. During the dry season, when green vegetation is scarce, giraffes may also consume more dried-out plants, including twigs and bark.
Giraffes spend a significant portion of their day feeding, up to 75% of their time during certain times of the year. They are active at night but are believed to feed more during moonlit nights and ruminate more during dark nights. They also adapt their diet based on the availability of food species in their specific region and season. For example, during the rainy season, they mostly consume deciduous species, while during the dry season, they rely on evergreen species.
The diet of giraffes can have an impact on their environment in several ways. Firstly, their feeding habits can shape the trees they feed from. For example, male giraffes, being taller than females, browse at higher regions of trees, potentially reducing competition for food between the sexes. Additionally, the giraffe's preference for acacia leaves and shoots can induce shoot growth in some Acacia species, and their feeding may trigger a defence response in the trees, leading to increased tannin production in the leaves.
Furthermore, the giraffe's feeding habits can influence the availability of food resources for other animals. During the dry season, when food is limited, smaller herd sizes among giraffes can reduce intra-group competition for food. This could potentially affect the foraging behaviour and opportunities of other species that share their habitat.
Lastly, the giraffe's diet may have indirect effects on the overall ecosystem dynamics. For example, their consumption of leaves and shoots from certain tree species could impact the availability of food and habitat for other organisms, including insects, birds, and other wildlife that depend on those plants. Additionally, as giraffes are often the earliest warning signal for other savanna wildlife, their feeding habits and movements can influence the behaviour and distribution of other species in their environment.

Giraffes are herbivores and have a plant-based diet. They are browsers, not grazers, and predominantly eat leaves from trees and shrubs, adapting their diet based on availability and nutritional needs. They also eat buds, branches, herbs, climbers, vines, flowers, and fruits.
Giraffes can spend up to 75% of their day feeding, and they eat between 1.6% and 2.1% of their body weight per day, which is around 75 pounds (34 kilograms) of food.
Giraffes have a long tongue and no upper front teeth, which help them to reach and chew leaves. They swallow the leaves first, then regurgitate them back up to chew again before it goes to the four compartments of their stomach for digestion.
Giraffes require a lot of water, which they get from the plants they consume and from drinking water every few days. They also need calcium due to their large, fast-growing skeleton. In the 1970s, it was recommended that giraffes be fed a low-fibre, high-protein diet to cope with peracute mortality syndrome.
