I went to buy some foodstuffs and on my way back I came across some Hausa men with a wooden cage by the roadside. Inside the cage were three porcupines.
It was the first time I came across such animals in real life. I was scared to pass or go near. The quills looked sharp enough to go through anything. But some kids were gathered around, laughing and trying to poke the porcupine in the cage with sticks.
Then it happened. One of the kids got poked by a quill that poked through the cage bars. He yelped and jumped back. Immediately, the men secured the cage properly and chased the kids away, shouting for them to leave the animals alone.
Standing there, heart still racing, I couldn’t stop wondering: _How do porcupines live? What do they eat? Why are they covered in those dangerous spikes?_
And what I found is that the porcupine is one of nature’s most misunderstood and fascinating survivors.
The Porcupine: More Than Just Spikes
Porcupines are rodents. Yes, they are in the same family as rats and squirrels, just... way more armored. There are about 30 species in the world, and they fall into two big groups: Old World and New World porcupines.
The ones I saw with the Hausa men were most likely old World porcupines, specifically the African crested porcupine. These are common in West Africa, including Nigeria. They are large, ground-dwelling, and have the thick, long quills we all fear.
1. The Spikes: A Masterclass in Defense
Let’s address the biggest myth first: porcupines do not shoot their quills
What are quills really?
Those "spikes" are actually modified hairs. Each quill is between 2-10 inches long, stiff, and hollow. The most dangerous part? The tip is covered in microscopic backward-facing barbs, like tiny fishhooks.
How the defense works:
A porcupine’s first move is not to fight. It’s to warn. When threatened, it will:
1. Rattle - It shakes its quills so they clatter together. It sounds like dry leaves and is meant to say "back off."
2. Turn around - It faces away from danger and raises its quills to look bigger.
3. Back into the threat - If you ignore the warnings and get too close, the porcupine will reverse into you. The quills are loosely attached and designed to detach on contact.
That’s how the kid in my story got poked. He got too close to the cage and a quill found him.
Why they hurt so much:
Those barbs are the problem. Once a quill is in your skin, the barbs catch and make it extremely painful to pull out. In the wild, the barbs can even cause the quill to slowly migrate deeper with muscle movement. That’s why predators like lions and hyenas learn one lesson and never touch a porcupine again.
Under all those quills, porcupines have soft, warm fur. And they carry over 30,000 quills on one body at a time. As quills fall out, new ones grow in.
The difference between Old World and New World porcupines matters here too. The African ones I saw have thick, long quills for ground defense. The American tree porcupines have shorter, thinner quills mixed with fur because they need to climb.
2. How Porcupines Feed: The Nighttime Herbivore
After seeing them in a cage, I wondered if they were meat-eaters. Nope. Porcupines are almost entirely herbivores
What’s on the menu:
Their diet changes with seasons, but generally includes:
- Tree bark and twigs - This is a favorite, especially in the dry season when other food is scarce. They use strong front teeth to gnaw through bark to get to the nutritious inner layer called cambium. This is why farmers sometimes see them as pests.
- Roots, tubers, and bulbs - They dig for these with their claws.
- Fruits, berries, nuts, and seeds - Anything sweet and available.
- Leaves and grass - Especially during the rainy season.
The salt craving:
Here’s the weirdest part. Porcupines have an intense craving for salt and minerals. In the wild they will chew on bones, antlers shed by deer, or even tools and clothes left outside that have human sweat on them. That’s why sometimes you hear stories of porcupines chewing car tires or wooden handles. They’re not being destructive, they’re looking for minerals.
How and when they eat:
Porcupines are nocturnal. They do all their feeding at night to avoid predators. Old World porcupines like the African species forage on the ground, using their sense of smell to find food. New World porcupines are expert climbers and will spend hours in trees eating leaves and bark.
Baby porcupines are called porcupettes. They are born with soft quills that harden within a few hours. By 2 weeks old they are already nibbling on solid food.
3. Habitat: Where Porcupines Call Home
The type of porcupine determines where it lives.
Old World Porcupines - Africa, Asia, Southern Europe
This is the group we have here in Nigeria. They are ground dwellers.
Their ideal habitat includes:
- Savannas and grasslands - Like many parts of Northern Nigeria
- Woodlands and forests
- Rocky hills, scrubland, and even deserts
- Farmlands - because crops are an easy meal
They don’t build nests. Instead, they dig burrows or take over caves and rock crevices. A good burrow has multiple entrances so they can escape if a predator like a hyena comes. Water must be nearby, and there needs to be plenty of vegetation.
New World Porcupines - North and South America
These are the tree porcupines. Their habitat is forests, both coniferous and deciduous. They spend 90% of their lives in the canopy, moving slowly from branch to branch. Their prehensile tails help them grip.
General needs for all porcupines: shelter, water, and food. As long as those three are present, porcupines are incredibly adaptable. That’s why you can find them from the Sahara’s edge to the American mountains.
Porcupines and Humans: Fear, Respect, and Use
In many African communities, porcupines are hunted for bushmeat. Their quills are also used for traditional crafts, jewelry, and even medicine in some cultures. But they play an important role in the ecosystem. By gnawing bark and spreading seeds through their droppings, they help forests regenerate.
The problem is misunderstanding. Like the kids at the roadside, people think porcupines are aggressive. They’re not. They are shy and would rather waddle away than fight. All the trouble starts when we get too close.
That night, after I got home with my foodstuffs, I kept thinking about those three porcupines in the cage. Scared, cornered, but still protected by the very thing that made people fear them.
The porcupine teaches us something important: you don’t have to be the biggest or fastest to survive. You just need good boundaries.
Their quills are a boundary. "Come close, but respect me." Their nocturnal life is a boundary. "I’ll live when it’s safe." Their diet is simple. "Eat what the earth provides."
In a world that tells us to be loud, to fight, to always be available, the porcupine survives by being careful, prepared, and knowing when to put its defenses up.
So the next time you see a porcupine, whether in a cage in Lagos or in a documentary, remember: don’t poke it. Admire it from a distance. Because behind those scary spikes is an animal that has mastered the art of peaceful survival for millions of years.
