Are Hedgehogs And Porcupines Related?

Are Hedgehogs And Porcupines Related

Welcome to our article on the fascinating topic of whether hedgehogs and porcupines are related! In this article, we’ll be exploring the scientific evidence that connects these two animals. We will look at their physical characteristics, behavior, diets, and habitats to determine if they belong to the same family. Finally, we’ll discuss why there is still some debate over whether or not they are indeed related. So without further ado, let’s get started!

The answer to the question of whether hedgehogs and porcupines are related is complex. While there is evidence that suggests they share some similarities, it is still unclear if they can be considered members of the same family.

Physical Characteristics:

At first glance, these two animals seem quite different. Hedgehogs have pointed snouts and short fur while porcupines have long quills covering their bodies. Additionally, hedgehog hind legs are longer than their front legs while porcupine hind legs are shorter.


Hedgehogs are solitary animals with a nocturnal lifestyle while porcupines tend to be more social creatures and active during both day and night. Another difference between the two species is that hedgehogs will curl up into a tight ball when threatened, whereas porcupines will use their sharp quills for self-defense.


  • Hedgehog diet consists mainly of insects, worms, fruits, vegetables, and eggs.
  • Porcupines prefer to feed on plants such as shrubs or tree bark but also consume small animals such as lizards or snakes.


  • Hedgehog habitats range from open fields to forests in Europe, Asia, Africa and New Zealand.
  • Porcupines live primarily in North America but can also be found in parts of South America, India, Sri Lanka and Southeast Asia.

The Fascinating Relationship between Hedgehogs and Their Closest Relative

Hedgehogs are small, spiny mammals found throughout Europe, Asia and Africa. They belong to the family Erinaceidae, which includes several closely related species. The closest relative of the hedgehog is the moonrat (Echinosorex gymnurus), an animal that is native to Southeast Asia.

Habitat and Diet

Both hedgehogs and moonrats inhabit similar habitats — moist forests with plenty of underbrush for shelter. Both animals feed on insects, worms, small vertebrates, fruits and fungi.

Physical Characteristics

  • Size: Moonrats are smaller than hedgehogs; they can grow up to 8 inches in length compared to a maximum size of 12 inches for a hedgehog.
  • Coat: Both animals have short fur coats with sparsely distributed spines or quills along their backs. However, while hedgehog spines are stiff and sharp-tipped, those of moonrats are softer and curved at the tips.
  • Color: Moonrats tend to be grayish-brown in color whereas most species of hedgehog have blacker coats with yellow or white bands across their faces.
  • Behavior: Both animals lead solitary lives but come together during mating season. They use vocalizations such as grunts, snuffles and chirps to communicate with each other over distances.

Discovering the Porcupine’s Closest Relative

The porcupine is a large rodent, belonging to the family Erethizontidae. It is one of the few animals that has quills or spines on its body as a form of protection from predators. The closest relatives to these unique mammals are not exactly clear, but there are several contenders.

Possible Relatives

  • Beavers: Beavers share many characteristics with porcupines, including their diet and burrowing habits.
  • Hedgehogs: Hedgehogs have similar behavior patterns and diets to porcupines, but do not have quills like the porcupine does.
  • Giraffes: Giraffes may be considered distant relatives because they belong to the same scientific order as porcupines (Rodentia). However, it is unlikely that they directly evolved from them.
  • Squirrels: Squirrels and other small rodents also belong to the Rodentia order. Although their diet and behaviors differ slightly from those of porcupines, they share many traits in common with them.

The Distinct Differences Between Hedgehogs and Porcupines

Hedgehogs and porcupines are two animals that are often confused due to their similarity in appearance. However, there are some distinct differences between the two of them that can help differentiate them.


  • Hedgehog: A hedgehog’s body is covered in short, bristly spines, which it can raise when threatened or scared. They usually measure about 10 inches long with a tail length of about 3 inches.
  • Porcupine: Porcupines have much longer coats of quills than hedgehogs do. The quills vary in color from brown to black and measure up to 8-10 inches long. They also typically weigh more than hedgehogs at around 18 pounds.


  • Hedgehog: Hedgehogs are solitary creatures who sleep during the day and become active at night. They feed on insects, worms, frogs, birds eggs etc.
  • Porcupine: Porcupines are more social animals who live in groups and prefer being active during the day. Their diet consists mostly of plants such as grasses, fruits, nuts, roots etc.


In conclusion, hedgehogs and porcupines are closely related animals that share many of the same physical and behavioral traits. They both have sharp quills or spines on their back which they use for defense. Although they look similar, there are also some key differences between the two species such as diet, size, and habitat. While these animals may be relatives in a sense, it is important to remember that they are not the same species and should not be treated as such when caring for either one.
