In 100 years of Safari, the leopard has become the animal most synonymous with Londolozi. We have watched them from the same riparian thickets for generations, named their bloodlines, tracked their cubs into adulthood, and unveiled the secrets behind this elusive cat. But for all the hours I have spent watching leopards here, it is often the smallest details that stop me in my tracks. This week, it was a paw.
A leopard’s claw is a small but intricate piece of engineering. Each one is made of keratin, the same protein in our own fingernails, but curved into a hook and kept needle-sharp. The claw is anchored not to the toe bone directly, but to a small (but incredibly strong and complex) tendon and ligament system that allows it to swing forward and back. When the leopard is relaxed, the claw sits retracted, tucked into a protective skin sheath so it never dulls. The moment the muscle contracts, the claw swings down and locks rigid, ready to grip bark, flesh, or ground.
Here is where the terminology gets interesting, and where I will admit most of us, myself included, have got it slightly wrong for years. We call a cat’s claws “retractable,” as though retraction is the active state. It is not. The resting state is retracted, but that happens passively, through elastic ligaments relaxing back into place. The active state, the one requiring muscular effort, is extension. Strictly speaking, a leopard’s claws are protractable, not retractable. It is a small correction, but it flips the whole mechanism on its head: the leopard is not working to hide its claws, it is working to reveal them.
This single adaptation explains so much of what we see on a game drive. It is why a leopard can walk in near-total silence across dry leaf litter while a hyena cannot. It is why a young leopard can climb to an impala carcass twenty feet up a jackalberry tree, and the scavengers below can only watch. It is a survival tool a hundred million years in the making, still switching on and off silently beneath the fur of every leopard walking this reserve today.
This process starts almost from day one. Leopard cubs are born with their claws already formed, unlike their eyes, which stay closed for the first week or so of life. And like our own fingernails, a leopard’s claws are not a single fixed structure for life. They grow continuously in layers, and a leopard sheds the outer layer periodically by raking it against the bark of a tree, revealing a fresh, sharp claw underneath.
If a claw is broken or torn out entirely, which does happen in fights over territory or with a struggling kill, the nail bed underneath can often heal and regrow a new claw over time, though a deep enough injury to the bone or joint can leave a permanent limp or a claw that never grows back quite true.
So next time you are watching a leopard, take a closer look. There is always more than meets the eye.
