Are Hedgehogs Rodents or Marsupials? [Explained Simply]


Today, we’re setting off on a quest to uncover the true nature of a rather spiky, often misunderstood creature—the hedgehog.

We’ve all seen these adorable balls of prickles, whether on the internet, in a friend’s home, or even in our backyard. But the question that often surfaces is this: are hedgehogs rodents or marsupials?

Quick Answer

Okay, let’s get straight to the point. Hedgehogs, despite being small mammals with an uncanny resemblance to rodents and having certain characteristics similar to marsupials, are neither.

They’re part of a unique family known as Erinaceidae. So, the quick answer is: No, hedgehogs are not rodents or marsupials. They belong to a completely different family, which we will explore more in the following sections.

It’s understandable why people might assume hedgehogs are rodents. They’re small, have similar eating habits, and share the same habitats as some rodents.

Likewise, hedgehogs’ ability to roll into a ball, somewhat resembling a marsupial’s pouch, can also lead to misconceptions.

Is a hedgehog a mammal or a rodent?

It’s a mammal, but not a rodent. Hedgehogs, like rodents and marsupials, fall under the mammal category due to their shared characteristics, such as having hair and feeding their young with milk. But that’s where the similarities end.

Hedgehogs: A Brief Overview

Hedgehogs, known for their unique, spiky exterior, belong to the family Erinaceidae. This family is divided into two subfamilies: Erinaceinae (which includes all types of hedgehogs) and Galericinae (which includes gymnures, also known as “hairy hedgehogs”).

Hedgehogs are nocturnal creatures, known to be quite solitary and, when threatened, are capable of rolling up into a ball, with their quills pointing outwards as a defense mechanism.

They’re native to parts of Europe, Asia, Africa, and were later introduced to New Zealand.

These adorable mammals are insectivores, meaning their diet primarily consists of insects. But hedgehogs are not picky eaters. They also chow down on plants, frogs, snails, worms, and even small snakes.

They are well-known for their immunity to some types of venom, which allows them to snack on creatures that other animals would avoid.

Fun Fact: Hedgehog quills come out as a remarkable defense mechanism against predators. When threatened, hedgehogs can shed their quills, making them an impressive and evasive survivalist in the animal kingdom.

Defining Rodents: What Makes a Rodent a Rodent?

Rodents form the largest group of mammals on Earth, accounting for about 40% of mammalian species. So what sets them apart? The key lies in their teeth.

Rodents are defined by a unique dental structure—specifically, a pair of continuously growing incisors in both their upper and lower jaws.

These teeth are fortified with a hard enamel surface on the front, while the back remains softer, allowing for a sharp, chisel-like edge perfect for gnawing.

Some common examples of rodents include rats, mice, squirrels, beavers, and guinea pigs.

While rodents and hedgehogs share a few traits, such as being primarily nocturnal and having similar dietary habits, they’re distinct in many ways.

The most notable difference lies in their dental structure. Unlike rodents, hedgehogs do not have continually growing incisors. Instead, they have a set of 36 to 44 teeth, including canine-like teeth that they use to crush the exoskeletons of insects.

Fun Fact: Hedgehog quills can grow back once shed, providing these spiky creatures with a remarkable self-defense advantage in the animal kingdom.

Marsupials Uncovered: What Makes a Marsupial a Marsupial?

On to marsupials! The most defining trait of marsupials is how they give birth and nurture their young. Marsupials give birth to undeveloped offspring that continue developing outside the womb.

Post-birth, these tiny creatures crawl into their mother’s pouch to continue their development and nurse.

Common examples of marsupials include kangaroos, wallabies, koalas, and possums. A surprising addition to the marsupial family is the Tasmanian devil—yep, that’s right, the one famous from cartoons!

Some might mistake hedgehogs for marsupials because of the hedgehog’s ability to roll into a ball. This behavior can be confused with the protective pouch of a marsupial.

However, the truth is, hedgehogs don’t have a pouch, and their young are much more developed at birth compared to marsupials.

Fun Fact: Hedgehogs may experience quill loss and dry skin due to various factors, including stress or health issues. Proper care and attention can help these adorable creatures maintain healthy quills and skin, ensuring they stay happy and thriving.

Why Hedgehogs Are Neither Rodents Nor Marsupials

We’ve taken a whirlwind tour through the worlds of hedgehogs, rodents, and marsupials. And by now, it’s clear that while hedgehogs share some characteristics with both these groups, they belong to neither.

As we discussed earlier, rodents are defined by their continuously growing incisors, a feature absent in hedgehogs.

Hedgehogs share some behavioral traits with rodents—like their dietary preferences for small critters and nocturnal habits—but from a biological classification perspective, they’re quite different.

On the other hand, Marsupials are set apart by their unique reproductive process, which involves giving birth to extremely undeveloped offspring that continue their growth in a pouch.

Hedgehogs, while they do curl up into a ball, do not have a pouch, and their young are more developed at birth.

Fun Fact: Hedgehog mites can cause dry skin and itching in these adorable creatures. Regular grooming and veterinary check-ups are essential to keep hedgehogs mite-free and their skin healthy, ensuring they stay cozy in their spiky coats.

Frequently Asked Questions (FAQ)

To wrap up our hedgehog exploration, let’s address some commonly asked questions about these prickly creatures:

Q1. What kind of animal is a hedgehog?

A hedgehog is a small mammal that belongs to the family Erinaceidae. They are known for their characteristic spiny coat and their ability to roll into a ball when threatened.

Q2. Are hedgehogs related to porcupines?

While hedgehogs and porcupines both sport a spiny exterior, they are not closely related. Porcupines are rodents with long, sharp quills, whereas hedgehogs are not rodents and have shorter, less sharp spines.

Q3. Can hedgehogs swim?

Yes, hedgehogs can swim! They are quite adventurers, capable of both climbing and swimming. Don’t believe us? Take a look at our article exploring whether hedgehogs are born swimmers!

Q4. How high can hedgehogs jump?

While hedgehogs are not known for their jumping skills, they can climb and scale walls with surprising agility. Curious to know more? Discover more about the athletic side of hedgehogs in our post about how high hedgehogs can jump.


There we have it! In this exploration of hedgehogs, rodents, and marsupials, we’ve unearthed the unique world of hedgehogs.

These spiky creatures, while sharing a few similarities with rodents and marsupials, ultimately belong to their unique family, Erinaceidae.

It’s an easy mistake to assume hedgehogs fall into the categories of rodents or marsupials. But as we’ve seen, the animal kingdom is full of surprises and nuances.

The classification of mammals is a complex field, with every creature having its unique place in the grand tapestry of life.

I hope this post has helped clarify the unique characteristics of hedgehogs and why they’re neither rodents nor marsupials. The world of animals is fascinating, filled with diverse creatures that continue to amaze and surprise us.

And remember, every animal, whether it’s a rodent, marsupial, or a proud member of the Erinaceidae family, like our friend the hedgehog, contributes to the amazing diversity of life on our planet.

So let’s celebrate these creatures and continue to learn more about them.
