How Do Hedgehogs Use Their Quills? Everything You Need to Know!

by

Hedgehogs are small, insectivorous mammals that are part of the Erinaceidae family. There are 17 different species of hedgehogs, and they can be found in various parts of the world. The most common species found as pets is the African pygmy hedgehog. Hedgehogs are known for their small size, round bodies, and spiny quills.

What are quills?

Quills are modified hairs that cover the body of hedgehogs. They are made of keratin, which is the same protein that makes up human hair and nails. Quills are hollow and have a sharp tip, which makes them an effective defense mechanism against predators. Hedgehogs have around 5,000 to 7,000 quills covering their body.

The Purpose of Quills

Self-defense

The primary purpose of quills is to protect hedgehogs from predators. When a hedgehog feels threatened, it will roll up into a tight ball, exposing its quills. The sharp tips of the quills make it difficult for predators to attack the hedgehog without getting injured. This defense mechanism is so effective that most predators will avoid attacking a hedgehog altogether.

Thermoregulation

Quills also play a role in thermoregulation. Hedgehogs are nocturnal animals and are active at night when temperatures are cooler. The quills help to insulate the hedgehog, preventing heat loss and keeping it warm in colder temperatures. In hotter temperatures, the quills lay flat, allowing air to circulate and cool down the hedgehog.

Physical Characteristics of Quills

Length and Thickness

The length and thickness of quills vary depending on the species of hedgehog. African pygmy hedgehogs, the most common species kept as pets, have shorter and less sharp quills compared to other species. The quills of other species, such as the long-eared hedgehog, can reach up to 2 inches in length and are very sharp.

Color

Quills can come in a variety of colors, ranging from white to black. African pygmy hedgehogs typically have brown or white quills, while other species may have more vibrant colors such as orange or red.

Behavioral Characteristics of Quills

How hedgehogs use quills to communicate

While hedgehogs primarily use their quills for defense and thermoregulation, they also use them to communicate. When a hedgehog is relaxed, its quills will lay flat against its body. However, when a hedgehog is excited or agitated, its quills will stand up, making it appear larger and more intimidating to predators. Hedgehogs may also raise their quills in response to stress or pain.

How hedgehogs maintain their quills

Hedgehogs maintain their quills by licking and grooming them. They have a special muscle near the base of each quill that allows them to control the angle of the quill. This muscle also helps them to remove any debris or dirt that may get stuck in their quills.

Myths and Misconceptions about Quills

Can hedgehogs shoot their quills?

Contrary to popular belief, hedgehogs cannot shoot their quills. Quills are firmly attached to the hedgehog’s skin and can only be released if a predator bites or attacks the hedgehog. Even then, the quills will only stick to the predator’s skin and not shoot out like projectiles.

Are quills poisonous?

Quills are not poisonous and do not contain any venom. However, if a human or animal is pricked by a quill, it can be painful and may cause swelling or infection.

Caring for Hedgehogs and Their Quills

How to safely handle a hedgehog

When handling a hedgehog, it is important to approach it slowly and gently. Do not grab or squeeze the hedgehog, as this can cause it to become stressed and release its quills. Instead, place your hand under its belly and let it rest on your hand.

How to care for hedgehogs with quill-related health issues

Hedgehogs can experience health issues related to their quills, such as infections or injuries. It is important to monitor your hedgehog’s quills for any signs of redness or swelling. If you notice any issues, take your hedgehog to a veterinarian who specializes in exotic pets.

Conclusion

Hedgehogs use their quills for self-defense, thermoregulation, and communication. Quills come in a variety of lengths, thicknesses, and colors. While hedgehogs cannot shoot their quills or poison predators with them, they are an effective defense mechanism. Caring for hedgehogs involves safely handling them and monitoring their quills for any health issues. With proper care, hedgehogs can live long and healthy lives, and their quills will continue to be an important part of their unique appearance and behavior. And no, hedgehogs cannot fly.
