Porcupines are relatively small mammals compared to a lion. They also represent the big cat’s complete opposite in many ways. Lions are a nearly unstoppable offensive force, especially when they attack in packs. However, porcupines are immovable objects because few animals want to risk getting stabbed by their quills. So, what happens in a porcupine vs lion fight? We’ll show you by looking at several qualities of these animals and determining the winner.

Comparing a Porcupine and a Lion

Lions are stronger and faster than porcupines.
SizeWeight: 12lbs-35lbs
Height: 1ft-1.5ft
Length: 1.2ft-2.5ft
Weight: 264lbs – 550lbs
Height: 3ft-3.9ft
Length: 4.7ft – 8.2ft
Speed and Movement Type– 2mph  – 35mph
Defenses– Sharp quills
– Composed of special hairs coated with keratin
– Some porcupines have groups of quills, and others have single quills spread out in their hair
– Can raise quills as part of a threat display
Threat display includes quill erection, tail rattling, growling, and a physical attack.
Stays with pride for safety in numbers
– Relatively large size as a carnivore frightens away many enemies
– Can quickly run away from enemies
Offensive Capabilities– Can flare their quills and walk backward to force animals to move in a certain direction
– Recent study shows these mammals running into other animals in an attempt to kill
– Only try to kill with quills in a dire situation or when they outnumber their foes
– Sharp claws can gash foes
– Paw strikes can deliver a powerful, staggering blow  
Strong biting power of 650 PSI- 1,000 PSI can splinter bones and tear prey open
Predatory Behavior– Herbivorous diet leads to no predatory behavior      – Endurance predator or ambush predator
– Works as a group to take down prey

What Are Key Differences Between a Porcupine and a Lion?

The biggest differences between a porcupine and a lion are their size and morphology. Porcupines are rodents with long hair and quills that can weigh between 12lbs and 35lbs and measure about 2.5ft long and 1ft-1.5ft tall. Lions are big cats that can weigh over 500lbs, grow between 4.7ft and 8ft long, and stand at a height of 3ft to 3.9ft tall.

These differences set the stage for an interesting showdown between these animals. We must consider if the porcupine has enough defense to stave off an attack from the lion, a massive, powerful animal. We’ll examine key factors that will help us decide the winner of the battle.

What Are the Key Factors in a Fight Between a Porcupine and a Lion?

The key factors in a battle between a porcupine and a lion will boil down to many of the same things we consider in other animal fights. We must examine differences in size, attack powers, defenses, and other elements to determine which creature has the advantage in each category. That’s the approach we’re going to take here. Using that data, we’ll be able to determine the winner of the battle.

Porcupine vs Lion: Size

Lions are larger than porcupines by quite a large amount. Lions weigh anywhere between 200 and 500lbs, stand up to 3.9ft tall, and can grow anywhere from 4ft-8ft long from head to tail. However, the porcupine only weighs about 12lbs, grows 1.5ft tall, and measures 2.5ft long.

The size disparity almost makes this battle an open and shut case. Few animals can survive against such a large opponent.

The lions have a definitive size advantage.

Porcupine vs Lion: Speed and Movement

Lions are much faster than porcupines. The average lion can reach speeds of 35mph and can hit a burst of speed up to 50mph when closing in on their foes during a hunt. However, a porcupine is a slow-moving animal that can move at about 2mph in the best cases.

The lions have the speed advantage.

Porcupine vs Lion: Defenses

Porcupines have one of the most unique and potent defenses in the animal kingdom. These rodents have fur interspersed with long, sharp quills. These special hairs are formed from keratin, forming a tough material that easily penetrates the skin of many animals.

Porcupines can raise these quills like an animal raising its hair. Once a foe attacks the porcupine, the quills stick in them. These quills break at the tip, leaving a painful barb in the offender’s skin. Once inside of their flesh, most animals have difficulty removing them.

The quills can cause abscesses to form, infections to take root, and death in some cases. Many animals that share a range with porcupines will make way for them to avoid these quills.

Lions use their size, pride, and speed to keep themselves safe. This combination is great at keeping lions near the top of the food chain in their range, but their defenses pale compared to the porcupine.

The porcupine has the defensive advantage.

Porcupine vs Lion: Offensive Capabilities

Lions have profound offensive capabilities when attacking prey. These animals have very sharp claws, powerful forelegs that they can use to deliver a staggering blow, and a very powerful bite force. With their speed and weight, few animals can stand up to a lion’s assault.

The porcupine doesn’t have much in the way of offensive powers. However, some studies have found that porcupines will run at their foes either sideways or backward to deliver an actual attack when they are desperate. Such attacks can be provoked when outnumbered or when several porcupines are set upon by predators.

Lions have more powerful offensive capabilities, and they know how to use them.

Porcupine vs Lion: Predatory Behaviors

Lions are deadly ambush predators as well as endurance predators. When they are alone or performing the opening salvo against prey, they will lie in wait for the opportune moment and strike. Lions have great senses of sight, smell, and hearing to tell them when prey is nearby.

If they are hunting in a pride, lions will harry and wear down their larger opponents, like zebra, and then bring them down to eat.

Porcupines are herbivores, and they have no true predatory behaviors. This lack of fighting instinct diminishes their ability to defend themselves.  

Who Would Win in a Fight Between a Porcupine and a Lion?

Lions have too much offensive power to lose a fight against the small rodent.


A lion would win a fight against a porcupine. You can go online right now and find videos of porcupines staving off attacks by lions with their quills. A lion may show no interest in going after these animals. Realistically, hunting animals is a matter of risk vs reward. In most cases, the porcupine is not worth the risk.

Yet, we can’t let this fight end at a stalemate with a porcupine crossing paths with a lion and the latter simply leaving it alone. We asked what happens in a fight between the two. Two outcomes are likely.

First, the lion is an ambush predator, and it’s fast enough that it could take a porcupine by surprise in the right situation, flipping it over and clawing or biting it to death.

The second and more interesting version is that the lion attacks the porcupine head-on. In this case, the lion uses its speed and agility to work its way around the porcupine while the rodent tries to back into it. The lion takes some quills to the face, chest, and legs but eventually scores the kill.

Simply put, unless the lion quits, the porcupine can’t win. Even if it did quit, that’s a stalemate and not a win for the porcupine. The only way porcupines have to kill is by using their quills. Quick aside, porcupines cannot shoot their quills. It’s nearly impossible for a porcupine to inflict enough damage on a lion with quills as to be immediately fatal.

So, in a true fight, the lion wins because the porcupine can’t do enough damage to kill the massive cat.

What Animal Can Defeat a Lion?


Bears are much better equipped to face off against lions than porcupines.


While the humble porcupine may prove to be no match for the feline ferocity of a lion, that doesn’t mean these big cats are completely invincible in the wild. Some other large predators can assert themselves to be a much more difficult challenge in battle with a lion.

Bears are one such predator. Using their staggeringly large statures and powerful claws, most species of bear would be able to counteract or withstand the swift pounces performed by a lion during a confrontation. Bears also possess a vastly superior bite force, being able to apply almost double the amount of pressure with their jaws than the lion. That means if a bear were able to get within biting range of its lion adversary, it would more than likely be game over.
