How Do Porcupines Care for and Raise their Young?

Two juvenile porcupine walking on green grass.

Porcupines are cute, prickly mammals that live in the desert, hills, and dense forests. They are very versatile, in that they can adapt to many different habitats. Because of this resilience, I became curious: how do porcupines care for their young?

Adapting to various surroundings by themselves is one thing; caring for and protecting their children in those differing environments is a whole other concern. The many methods porcupines have for taking care of their kids are interesting—here is a breakdown of some of them.

How do Porcupines Feed Their Children?

The diet of porcupines consists largely of veggies, fruits, and various herbs. Porcupines are primarily herbivores. A particularly fascinating aspect of porcupines is how they obtain food, and how they provide food for their children.

Their herbivorous diet is just as diverse as the locales they can be found in. This is also because their selection of foods changes with the seasons. One of the most common ways porcupines get food for their young is from trees.

The parent porcupines will lead their children to the base of a tree they want to get food from. For safety, the kids will stay huddled together at the bottom of the tree. Then, the parent or parents will begin their climb upward.

The kids will just have to wait patiently for their meal to arrive. Porcupines will eat tree bark and pine needles, which are a good source of sustenance in winter. They also eat grass on occasion.

Once the parent(s) are back from their trip up the tree, their young will have something tasty to snack on. While it is not the primary part of their diet, porcupines do eat meat. They do not prey on other animals to do this, however, and only eat meat when their options are very limited.

The only method of gathering meat is when they find animal remains. This makes this portion of their diet solely out of survival needs. Keeping the kids fed and happy is one aspect of care.

What about when they have to battle the elements?

How Do Porcupines Stay Warm?

A porcupine standing on a snow covered log in winter.

Porcupines don’t hibernate, so they need to prepare for cold months, especially since they can be found in places that get very cold in the winter, such as Alaska. They start the winter with as much as half their weight being fat. With the knowledge of the warmer places to bed down, help from a thick undercoat, and this added fat, they can get through most winter conditions.

These prickly little critters have developed a complete routine to keep themselves warm. Let’s take a look.

Storing Fat

Biologist Jessy Coltrane spent time in Alaska studying the porcupines for a paper. She monitored several of these little creatures and made the discovery that at least fifty percent of the weight they carried going into winter was fat. Throughout the winter, they moved very little, reserving their energy and living off that stored fat when they were unable to get out to eat.

In order to reserve as much energy as possible, they moved very rarely and did sleep a lot.

Winter Coat

The coat is a porcupine and is multi-layered. It consists of a wooly undercoat that is made up of soft hairs. This coat is covered with coarse guard hairs that help protect the porcupine itself.

Then the areas of its back, tail, and sides are covered with quills, which are hollow, allowing for the air inside to be warmer from its body heat. Normally, the body temperature of a porcupine is that of humans, and scientists have discovered that both hot and cold temperatures don’t cause it to vary much because of this protection. In addition, many types of porcupines grow an additional layer of fur on the outside that looks like a wooly winter coat and adds protection from the cold.

Homebodies

Porcupines are very fond of living in trees but during the winter they seek out areas that can protect them from the wind, keeping them warmer. They have a preference for rocky ledges with crevices but will also utilize hollow trees or the deserted dens of beavers and other animals.

How Many Tropical Rainforests Are There?

Dense tropical forest in the Chiew land lake.

One of my favorite facts about rainforests is that they’re cornucopias of life. According to worldrainforestday.org, rainforests contain about 50% of all terrestrial biodiversity. But, how many rainforests are there to be able to harbor such a considerable amount of ecosystems?

Well, scientists don’t usually refer to the number of rainforests in the world per se. Instead, they talk more about the amount of rainforest coverage in the world.

Tropical Rainforests Vs. Temperate Rainforests

This article talks about how many tropical rainforests there are in the world. However, tropical rainforests are only one type of rainforest. Rainforests are mainly divided into tropical and temperate rainforests.

Both tropical and temperate rainforests are located between the Tropic of Cancer and the Tropic of Capricorn. Rainforests are found on every continent, with the exception of Antarctica.

The main difference between tropical and temperate rainforests is that tropical rainforests are located closer to the equator, where the temperatures are warmer. On the other hand, temperate rainforests are found to the north and the south of the equator, along the cooler coastal regions. In addition, temperate rainforests have less biodiversity and receive fewer inches of rain per year.

For a rainforest to be classified as such, it must receive 60-80 inches of rainfall each year. Generally, a rainforest is defined as a forest that gets a lot of rainfall. In fact, it rains throughout the year in the tropical rainforest, and the environment is always hot and moist.

Another characteristic of rainforests is the four distinct layers.

  • Emergent layer. Emergents are the tall, giant trees that grow above the general canopy. Their height ranges from 70 to 100m.
  • Canopy layer. The canopy layer is the largest part of the rainforest, and the trees here also grow to be very tall. The canopy layer overlaps so much it creates a roof over the forest that prevents sunlight from reaching the forest floor.
  • The understory. The understory is a humid and damp level made up of smaller plants and trees, such as vines and palms. These plants have adapted to environments where there’s little

Can Porcupines kill Snakes? Cats? Chickens?

Porcupines are generally not aggressive animals; however, they will react if attacked. Their quills can be very sharp and painful for any animal or human being who tries to threaten them. Here is a closer look at the traits of a porcupine and whether or not they are a danger to other animals.

What is a Porcupine?

Portrait of Indian porcupine in the wild.

Erethizon Dorsatum, better known as the North American porcupine, is a mammal in the rodent family notable for its quill-covered bodies. Adult porcupines have about 30,000 quills covering their bodies, used for defense and keeping their bodies warm in the winter. Contrary to popular belief, the quills of a porcupine are not poisonous.

However, they are very sharp and can cause serious injury to any other animal who comes in contact with them. The quills also have barbs at the end, making them painful to remove. Porcupines are slow-moving creatures that are natural herbivores, so they are not known to be aggressive or hostile to other animals.

But if attacked, they will use their quills to ward off other predators. They can’t shoot their quills at an attacking animal, but they will use their body to target specific areas on a predator’s body.

Can Porcupines Kill Snakes?

Even though porcupines are the second-largest rodent on earth, snakes are known to occasionally target them as prey. Snakes like pythons and vipers are known for swallowing a porcupine’s whole, which can often be a deadly mistake. A study published by the Phyllomedusa Journal of Herpetology in 2003 found that porcupine quills are sharp enough to pierce through the body of a snake.

So, if a snake tries to swallow a porcupine whole, it can cause severe injury and even death from the impact of the quills. It turns out that it’s rare for porcupines and snakes to encounter one another, but it does occur. Another similar study cited more than ten documented instances of porcupines harming snakes, with an estimated survival rate of 33%.

Porcupines are a high-risk meal for a hungry viper or python. But if they are hungry enough or don’t see … Read the rest of the story.


How Many Teeth Do Porcupines Have?

A portrait photo of porcupine in wild showing his teeth.

Porcupines have twenty teeth. This includes four incisors and 16 molars. Like many members of the rodent family, their front two molars never stop growing.

Unlike other rodents, their teeth are bright orange in color. With so many teeth, you would think that these animals would bite when fighting, but they are not known for biting. They do use their teeth in a unique way when they are defending themselves, however.

We will find out how a bit later. Let’s take a deeper look into porcupine teeth and their unusual qualities.

Always Growing

A portrait of porcupine on a sunny day.

Incisors on a porcupine never stop growing. This could become a problem if the porcupine doesn’t find a way to grind the teeth down to a manageable size. If they become too long, he won’t be able to eat. Being plant-eaters, the food a porcupine eats doesn’t do much in the way of helping to grind the teeth down.

This is why you often find porcupines gnawing on tree bark. In addition to tree bark, porcupines will gnaw on deer antlers that have fallen off in the winter. In addition to helping grind the teeth to a manageable size, the antlers help provide salt and other minerals that the porcupine needs to be healthy.

Porcupines can also be found munching on boat oars and other wooden objects around the camps of humans. They seem to be particularly attracted to things that are covered in human sweat. This is most likely because the sweat contains salt, which is something that all porcupines crave and will actively seek out.

Orange Teeth?

Something that may surprise you if you happen upon a porcupine is that they are bright orange in color. This is because the teeth contain a high amount of iron oxide that makes up the enamel. Not all rodents have this color, but porcupines do share this trait with beavers.

The mineral iron that makes up the enamel allows the coating of the teeth to become stronger than if the coating contained the traditional magnesium that makes up most teeth enamel.

This allows the porcupine to … Read the rest of the story.


What Do Porcupines Like to Do?

Portrait of indian porcupine in the wild.

Even though porcupines are best known for their sharp quills, there’s more to these rodents than meets the eye! Porcupines are nocturnal creatures, which means they’re mostly active at night. During this time, it’s common to see porcupines foraging for food, munching on grass, or even climbing trees!

You might also find a porcupine in the water! While porcupines might not look like natural swimmers, their quills are actually filled with air that helps make them more buoyant. Swimming gives porcupines access to a wider range of food sources and can also help them to escape from predators.

What Do Porcupines Like to Eat?

A porcupine actively eating plants in the field.

Porcupines are herbivores, which means they primarily eat plants. While their diets can vary based on the season, some of the foods they enjoy include grass, stems, bark, nuts, and fruit.

Although porcupines mostly eat food that they find scattered on the ground, they’ll pull branches, bark, and leaves from trees when they need more to eat.

When they’re in the water, porcupines seek out water plants, such as water lilies and arrowheads. Since the predators that are a threat to porcupines primarily live on land, swimming skills help to ensure that porcupines always have access to food when they need it. Porcupines that are kept in captivity may enjoy a wider range of foods.

Maggie, one of the Brookfield Zoo’s animal specialists, says that porcupines have the chance to try many different treats. “We like to offer animals all kinds of enriching items so that they can explore different things and get new items in their diet,” she says. “Every once in a while [our porcupines will] get new exciting items, like a piece of sugarcane.”

Are There Different Types of Porcupines?

A threatened North American porcupine.

There are more than 50 different porcupine species worldwide. These species belong to two different families: Old World and New World porcupines. These families vary in a number of ways.

Old World Porcupines

Species in this family are native to Africa, Asia, and Italy. They’re round, stout, and have flattened quills. These porcupines tend to be much larger than species in the … Read the rest of the story.


Can Porcupines Float in Water? How?

Porcupines are great swimmers. That is, some breeds of them are. The North American porcupine, the crested porcupine, and the brush-tailed porcupines all love swimming!

You can go for a walk in a wooded area and probably wouldn’t be surprised to come across a porcupine nibbling on leaves or berries. Having one fall out of a tree might surprise you for a minute, but you wouldn’t think it out of place.

However, can you imagine walking along a beach or taking a swim and coming across one of these prickly critters passing you? It just might happen.

The Nature of Porcupines

Porcupines live in many different areas but normally stick with areas where they can climb trees or find roots and other small areas to hide in. While they have great protection with all those quills, these animals are by nature very docile and prefer not to fight. On land, they are clumsy and slow.

Normally, they are satisfied with the food they can find where they live. Like humans, however, they may get cravings for a certain delicacy that can only be found in water and they will set off to find it. In the water, they are quite agile and move quickly.

How Porcupines Swim

The average porcupine has over 30,000 quills covering its back, legs, and tail. Each of these quills is actually hollow inside and very lightweight. The hollow space is filled with air and this allows the quills to float.

With so many attached to the porcupine’s body, they work like little life jackets and keep it afloat. It probably doesn’t hurt that their little round bodies would also lend themselves to buoyancy! Once the porcupine is afloat, it can use its paws like a dog paddling in the water.

This moves him ahead and helps him control the direction he wants to head in.

Why Porcupines Swim

It is possible that some porcupines just like being in the water. It can cool them in the summer and they are less likely to be bothered by predators. We haven’t found one that can … Read the rest of the story.
