A grouping of giraffes is called a “tower,” which is the reason for today’s heading. Although we spotted seven giraffes in this tower, we could only photograph three or four simultaneously, as they wandered off and onto the road.
Giraffes may seem gentle and graceful with their long necks and slow strides, but don’t be fooled. These towering herbivores are surprisingly strong and powerful animals. Beneath their elegant appearance lies a combination of muscular strength, defensive power, and anatomical efficiency that allows them to survive and thrive in the wilds of Africa.
Let’s start with one of the most striking features of the giraffe: its neck. The average adult giraffe’s neck is around six feet long and can weigh up to 600 pounds. Despite its length, a giraffe’s neck has the same number of vertebrae as most mammals—seven—but each vertebra is significantly elongated and supported by powerful muscles and ligaments. These muscles aren’t just for holding the neck upright; they play a key role in one of the giraffe’s primary forms of defense and dominance: necking.
Necking is a form of combat between male giraffes where they swing their necks like sledgehammers, using their heavy skulls to strike their opponent. These blows can be powerful enough to knock down or even seriously injure a rival. Observers of giraffe fights often describe the sound of impact as loud and startling, a testament to the force these animals can generate. The winner of such contests earns mating rights with nearby females, so strength really does equal survival in this case.
Beyond their necks, giraffes possess powerful legs, especially their hind legs, capable of delivering a deadly kick. A single well-placed giraffe kick can crush a predator’s skull like a lion’s. Giraffes are known to kill lions with these kicks, and this natural defense mechanism makes adult giraffes a risky target for even the most formidable predators. Their legs are weapons and tools for speed: giraffes can run up to 35 miles per hour over short distances. However, they generally prefer a slower, energy-efficient pace to conserve stamina.
Regarding raw physicality, giraffes must be strong to support their size. Adult males can grow to nearly 18 feet tall and weigh up to 3,000 pounds. A giraffe has an exceptionally strong heart to pump blood from the heart to the brain, over six feet upward. It weighs up to 25 pounds and can pump blood at twice the pressure of a human heart. This high blood pressure is necessary to maintain brain function, especially when the giraffe suddenly raises or lowers its head.
The giraffe’s strength is not just muscular or mechanical—it’s also evolutionary. Their height and strength allow them to reach food that other herbivores can’t, reducing competition and allowing them access to leaves high in the treetops. Their long tongues—up to 18 inches—are tough and prehensile, capable of wrapping around and stripping leaves from thorny branches, like those of the acacia tree.
So, how strong are giraffes? They’re strong enough to defend themselves against lions, strong enough to fight each other in brutal battles for dominance, strong enough to run quickly despite their size, and strong enough to circulate blood to their heads without fainting. Their strength isn’t loud or flashy—it’s quiet, efficient, and built into every part of their being.
In the animal kingdom, strength doesn’t always look like a roaring lion or a charging rhino. Sometimes, it seems like a calm, towering creature grazing peacefully—until it’s time to show how powerful it is.
Spotting these giraffes on the road was a delightful experience as we continued our day trip through Kruger National Park. We encountered one treasured sighting after another, leaving us with memories of a well-spent day.
Be well.
