Have you ever seen a group of porcupines? Probably not. With their coats of sharp quills, porcupines have naturally mastered the art of personal space.
Despite their intimidating appearance, though, porcupines aren’t looking for a fight. Their quills are designed for protection, not aggression, and most would rather avoid a confrontation altogether. While many porcupines prefer a solitary lifestyle, some species are surprisingly social, sharing shelters and spending time with family members.
So, what do you call a group of porcupines, and how often do these spiny animals actually gather? The answer might just make you smile.

What Is a Group of Porcupines Called?
A group of porcupines is called a prickle, according to The San Diego Zoo Wildlife Alliance. It’s one of the more descriptive collective nouns in the animal kingdom, referring to the sharp quills covering much of these mammals’ bodies.
The name is especially fitting considering that a single North American porcupine can have approximately 30,000 quills. Imagine encountering several of these heavily armored animals together!
However, porcupines don’t usually travel in large groups. Depending on the species, they may live alone, in pairs or in small family groups.
Why Is a Group of Porcupines Called a Prickle?
The name “prickle” is an obvious reference to the porcupine’s most recognizable feature: its sharp, needle-like quills. The exact historical origin of the collective noun isn’t firmly documented, but the connection to the animal’s appearance is easy to understand.
The word prickle can describe a sharp point or a prickling sensation. Applied to porcupines, it creates a particularly vivid image of several spiny animals gathered together.
Interestingly, porcupines aren’t actually covered in ordinary thorns or needles. Their quills are modified hairs made of keratin, the same protein found in human hair and fingernails. The National Park Service explains that these specialized hairs help protect porcupines from predators and can detach when another animal makes contact with them.
Do Porcupines Actually Live in Groups?

Although their collective name suggests a gathering, porcupines aren’t typically highly social animals. New World porcupines generally spend their time alone or in pairs, while some Old World species are more social.
Old World crested porcupines may live in family groups and share underground shelters. These animals are found in parts of Africa, Europe and Asia.
North American porcupines, by contrast, are generally solitary outside the breeding season. Mothers also spend time with their offspring until the young become independent.
In other words, a prickle of porcupines is a legitimate collective noun, but it doesn’t necessarily describe how these animals spend most of their lives.

What Is a Baby Porcupine Called?

A baby porcupine is called a porcupette. It’s an unexpectedly adorable name for an animal that eventually develops thousands of sharp quills.
Porcupettes are born with soft, flexible quills that begin hardening shortly after birth. According to National Geographic, female porcupines typically give birth to between one and four young, depending on the species.
Young porcupines depend on their mothers for nourishment and protection while developing the skills needed to survive independently. Although their quills become sharp relatively quickly, porcupettes still need time to learn how to forage and avoid danger.
What Are the Two Main Types of Porcupines?
Porcupines are divided into two major families, each with distinctive characteristics.
Old World Porcupines

Old World porcupines belong to the family Hystricidae and live in Africa, Europe and Asia. These animals are primarily ground-dwelling and often have long, conspicuous quills. Some species, including crested porcupines, can raise their quills into an impressive defensive display.

New World porcupines belong to the family Erethizontidae and inhabit North, Central and South America. Many are excellent climbers, spending considerable time in trees. Both groups rely on their quills for protection, but their habitats, physical characteristics and social behaviors differ.
7 Fascinating Facts About Porcupines
Porcupines have several remarkable adaptations that make them much more interesting than their prickly reputation suggests.
1. Porcupines Cannot Shoot Their Quills
Despite a persistent myth, porcupines cannot launch their quills at predators. The Smithsonian’s National Zoo explains that quills are loosely attached and can detach when another animal makes contact with them. A threatened porcupine may raise its quills, turn its back or strike with its tail.
2. Some Porcupines Have Around 30,000 Quills
North American porcupines can have approximately 30,000 quills covering their bodies. These specialized hairs contain tiny barbs that make them difficult to remove once embedded in another animal’s skin. Porcupines naturally replace quills they lose.
3. Porcupines Are Rodents
Porcupines belong to the order Rodentia, making them relatives of squirrels, beavers and mice. Like other rodents, they have continuously growing front teeth that help them gnaw through tough plant material.
4. Many Porcupines Are Excellent Climbers
North American porcupines frequently climb trees to feed on leaves, bark and buds. Their strong claws help them grip branches, while their tails provide additional stability. Some South American porcupines have prehensile tails specially adapted for grasping branches.
5. Porcupines Are Primarily Plant Eaters
Porcupines are herbivores that eat a variety of vegetation, including leaves, bark, roots, fruits and stems. Their diets change with the seasons and available food sources.
6. Porcupines Sometimes Chew on Bones
Although they primarily eat plants, porcupines occasionally gnaw on animal bones and shed antlers. This behavior helps them wear down their continuously growing incisors and also obtain minerals like calcium that may be limited in their regular diets, reports the Groundswell Conservancy on Facebook.
7. Porcupines Can Swim
Despite their bulky appearance, porcupines are capable swimmers. The National Park Service notes that North American porcupines’ hollow quills help them stay afloat. Their swimming ability is another example of how well these animals have adapted to their environments.
What’s the Difference Between a Porcupine and a Hedgehog?

- Porcupines and hedgehogs both have prickly defensive coverings, but they’re not closely related.
- Porcupines are rodents, while hedgehogs belong to a different mammalian order, Eulipotyphla.
- Hedgehogs are generally smaller and have relatively short spines. Many curl into tight balls when threatened, protecting their vulnerable undersides.
- Porcupines, meanwhile, have longer quills that can detach during contact with predators. Rather than rolling into balls, they typically rely on raising their quills and presenting their protected backs.
- Their diets also differ. Hedgehogs eat many invertebrates, while porcupines primarily consume vegetation.
Why the Name Prickle of Porcupines Makes Sense
Few collective nouns describe an animal’s appearance as perfectly as “a prickle of porcupines.” The name immediately brings to mind their impressive coat of defensive quills, even though these mammals rarely gather in large groups.
And while porcupines may look threatening, their sharp defenses are primarily intended to keep predators away. For an animal that generally prefers a peaceful, solitary existence, “prickle” is an amusingly appropriate name.
