Porcupines are relatively small mammals compared to lions. They also represent the complete opposite of big cats in many ways. Lions are an almost unstoppable attacking force, especially when they attack in packs. Porcupines, however, are immovable objects because few animals are willing to risk being stabbed. So, what happens when the porcupine vs. the lion? We’ll show you by looking at several qualities of these animals and identifying a winner.

What is the main difference between a porcupine and a lion?

The biggest difference between porcupines and lions is their size and morphology. A porcupine is a long-haired, spiny rodent weighing between 12 and 35 pounds, about 2.5 feet long and 1 to 1.5 feet tall. Lions are big cats that can weigh over 500 pounds, measure between 4.7 feet and 8 feet in length, and stand between 3 feet and 3.9 feet tall.
These differences set the stage for an interesting showdown between these animals. We have to consider whether porcupines have adequate defenses against an animal of such size and strength as a lion. We’ll look at the key factors that help us decide whether to win or lose.

The Best Sheep Shears You Really Want to Use
The key factors in a fight between a porcupine and a lion will come down to many of the same factors that we consider in other animal fights. We had to examine differences in size, attack power, defense, and other elements to determine which creature had the advantage in each class. That’s the approach we’re going to take here. Using this data, we will be able to determine the winner of this battle.
Porcupine vs. Lion: Size
Lions are much larger than porcupines. Lions weigh between 200 and 500 pounds, stand up to 3.9 feet tall, and can vary in length from 4 to 8 feet from head to tail. However, porcupines only weigh about 12 pounds and measure 1.5 feet by 2.5 feet.
The disparity in size almost makes the battle an unresolved case. Few animals can survive such a massive opponent.
Lions have an absolute size advantage.
Porcupine and Lion: Speed and Movement
Lions are much faster than porcupines. Lions can reach an average speed of 35 mph and can reach burst speeds of 50 mph when approaching an enemy during a hunt. However, porcupines are slow-moving animals, moving at about 2 mph in the best of circumstances.
Lions have the speed advantage.
Porcupine vs. Lion: Defense
Porcupines have one of the most unique and powerful defenses in the animal kingdom. These rodents have long, sharp quills scattered throughout their fur. These specialized hairs are formed from keratin, which forms a tough material that easily penetrates the skin of many animals.
Porcupines can bristle these setae in the same way animals bristle their hair. Once the enemy attacks the porcupine, the spines will stick to the body. These bristles snap off at the tips, leaving painful barbs in the offender’s skin. Once in the flesh, most animals have difficulty getting it out.
Quills can cause abscesses to form, infections to take root, and in some cases, death. Many animals that share 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 for keeping lions near the top of the food chain within their range, but their defenses pale in comparison to porcupines.
The Porcupines have a defensive edge.
Porcupines vs Lions: Offensive Power
Lions have a deep attack when attacking their prey. These animals have very sharp claws, powerful front legs that they can use to deliver a stunning blow, and a very powerful bite. With their speed and weight, few animals can withstand a lion’s attack.
Porcupines don’t have much attack power. However, some studies have found that porcupines, in desperation, will run sideways or backwards toward their enemies in order to actually attack. Such attacks can be triggered when there are outnumbered or when a few porcupines are attacked by a predator.
Lions have more powerful attacks, and they know how to use them.
Porcupines and Lions: Predatory Behavior
Lions are deadly ambush predators as well as endurance predators. When alone or making an opening salvo on prey, they lie in wait for the right moment to strike. Lions have excellent senses of sight, smell and hearing and can tell when prey is nearby.
If they hunt in groups, lions will prey on and wear down their larger rivals, such as zebras, before bringing them down and eating them.
Porcupines are herbivores, they have no real predation behavior. A lack of fighting instincts impairs their ability to defend themselves.
Who would win a fight between a porcupine and a lion?

The Lions win the fight against the Porcupines. You can find videos of porcupines fending off lions with quills online right now. Lions probably have no interest in chasing these animals. In reality, hunting animals is a matter of risk versus reward. In most cases, porcupines are not worth the risk.
However, we cannot allow this battle to end in a stalemate where the porcupine crosses the road and the lion simply ignores it. We asked what would happen in a fight between the two. There are two possible outcomes.
First, lions are ambush predators, fast enough to surprise porcupines under the right circumstances and claw or kill them.
The second, more interesting version has the lion attacking the porcupine head-on. In this case, the lion uses its speed and agility to get around the porcupine, while the rodent tries to get back to the porcupine. The lion was stabbed several times in the face, chest and legs, but ultimately killed it.
Simply put, the Porcupines cannot win unless the Lions back out. Even if it did pull out, it would be a stalemate rather than a victory for the Porcupines. The only way porcupines have to kill is with their quills. hurry up, Porcupines cannot shoot their quills. It is almost impossible for a porcupine to inflict enough damage to a spiny lion to be instantly fatal.
So, in a real fight, the lion won because the porcupine couldn’t do enough damage to kill the giant feline.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
