Giraffes (Giraffa) are iconic African mammals known for their towering height and graceful presence. They are the tallest land animals on Earth, with adult males reaching up to 18 feet (5.5 metres) tall and females reaching 14-16 feet (4.3–4.9 metres).
Much of their height is due to their incredibly long necks, which can measure up to 6 feet (1.8 metres) long. However, giraffes also have long legs that contribute to their overall stature. Each leg measures around 6 feet (1.8 metres) long!
Uniquely Adapted for Their Height
A giraffe’s long neck is not just for show. It contains the same number of vertebrae as a human neck (seven), but each vertebra is much longer. This allows them to reach leaves and branches high in trees that other herbivores can’t access, giving them a significant advantage in their environment.
To support their great height and pump blood all the way to their heads, giraffes have a unique circulatory system. Their heart weighs around 25 pounds (11 kg) – much larger than the human heart – and they have specialised blood vessels that help regulate blood flow and prevent their brains from being flooded with blood when they raise their heads.
More Than Just Height
Giraffes are herbivores, primarily feeding on leaves from trees, especially acacia trees. Their long tongues, which can extend up to 18 inches (45 cm), are specially adapted to grasp branches and navigate thorny acacia trees without getting hurt. They can consume up to 75 pounds (34 kg) of leaves daily!
Despite their size, giraffes are surprisingly fast. They can run at speeds up to 35 miles per hour (56 km/h) in short bursts and can maintain a steady pace of 10 miles per hour (16 km/h) over longer distances. This speed helps them escape predators and move efficiently across the African savanna.
Distinctive Patterns and Social Behaviour
Each giraffe has a unique coat pattern, consisting of patches that vary in shape, size, and colour. These patterns range from light tan to dark brown, providing excellent camouflage in the dappled light of the savanna.
Giraffes are social animals that live in loose herds called “towers”, an apt name considering their height. These herds typically consist of females and their young, while males often roam alone or form bachelor groups. The social structure is fluid, and giraffes frequently move between different groups.
Although they are generally peaceful, male giraffes engage in a behaviour called “necking” to establish dominance over mating rights. This involves swinging their powerful necks at each other in a display of strength.
Conservation Status
While giraffes are not currently classified as endangered, some subspecies, like the reticulated giraffe, are considered vulnerable. Habitat loss, poaching, and human-wildlife conflict threaten giraffe populations across Africa. Conservation efforts are underway to protect these majestic creatures and ensure their survival for future generations.
