Hedgehog Basics
Hedgehogs are fascinating mammals with unique physical characteristics and behaviors.
They’re widely recognized for their spines, which are actually modified hairs made of keratin.
Let’s explore the fundamental aspects of these creatures, from their distinct species and habitats to their diets and life cycles.
Physical Characteristics
Hedgehogs are small mammals, most known for their covering of sharp spines.
A hedgehog’s body can measure up to 30 cm in length, with a short tail adding an extra 1-2 cm.
Their weight varies from 400 grams to over 1 kg depending on the species and environmental conditions.
The European hedgehog, Erinaceus europaeus, is one of the most well-known species.
Hedgehogs use their spines, not as porcupines do for actively defending by embedding them into predators, but as a passive defense mechanism by curling into a ball.
Their face and underside are covered with softer fur, giving balance to their otherwise prickly exterior.
Species and Distribution
There are several species of hedgehogs distributed across Europe, Asia, and Africa.
These include the European hedgehog commonly found in woodlands, the long-eared hedgehog dwelling in steppes and desert areas of Western Asia, and the African pygmy hedgehog which has gained popularity as a domesticated pet.
Desert hedgehogs are found in arid regions such as North Africa.
Hedgehogs’ ability to adapt to a range of habitats from forests to grasslands contributes to their wide distribution.
Diet and Foraging
A hedgehog’s diet consists mostly of insects, snails, frogs, worms, and a variety of ground-dwelling creatures.
These nocturnal foragers are also known to partake of berries and fruits, diversifying their diet when the opportunity arises.
Their keen sense of smell guides them to food, and their robust digestive systems allow them to process a vast range of invertebrates, which form the bulk of their diet.
Reproduction and Lifecycles
Reproduction for hedgehogs begins with a gestation period that lasts about 35 to 58 days.
They give birth to a litter which can range from 1 to 11 hoglets, although litters of 4 to 5 are most common.
At birth, hedgehogs’ spines are soft and covered by a protective membrane, which hardens within a few hours.
The hedgehogs’ life cycle involves nurturing their young in nests until they can forage on their own.
Hedgehogs are solitary creatures outside of the breeding season and will typically only come together for mating.

Hedgehog Behavior and Ecology
Hedgehogs boast an intriguing array of behaviors and adaptations that help them thrive in various environments, from grasslands to urban gardens.
Their survival strategies, ranging from unique defense mechanisms to hibernation habits, paint a vivid picture of adaptation.
Habitats and Shelter
Hedgehogs are found in a wide array of habitats, including forests, grasslands, and often in gardens which provide plenty of food and shelter.
They create nests from leaves and grass or take advantage of burrows left by other animals.
While they are known for their solitary lifestyle, during the day, they rest in these hidden spots away from the prying eyes of predators.
Defense Mechanisms
When threatened, a hedgehog’s primary defense is its spines.
These are not barbed, but rather are stiff, hollow hairs that can be raised when danger is near.
This behavior, often referred to as “quilling,” can deter many would-be attackers.
Common predators include foxes and snakes, but the effectiveness of hedgehogs’ spines often gives them an excellent chance of escaping unscathed.
Hibernation Patterns
Hedgehogs are one of the few mammals native to Europe that hibernate.
When temperatures drop and food becomes scarce, they will enter a state of hibernation which can last from October to April.
During this period, they settle in a specially prepared burrow or nest on the ground, reducing their metabolic rate to conserve energy.
This adaptive strategy is crucial for their survival during the cold months when foraging for food would be incredibly challenging.
Hedgehog Care and Legal Aspects
Hedgehog enthusiasts must consider legal regulations and specific care requirements to ensure the well-being of these delightful creatures.
Unlike common pets, hedgehogs require attentive care and are subject to different laws.
Domesticating Hedgehogs
Hedgehogs can be novel and affectionate pets, with the African Pygmy breed being the most popular in domestic settings.
This petite species has a friendly demeanor and adapts well to life in captivity, provided they receive proper care.
For a balanced diet, a mixture of commercial hedgehog food, along with occasional treats like insects or cooked eggs, is recommended.
To exhibit their natural foraging behavior, they need a habitat that includes ample space, hiding spots, and items to explore.
Most notably, a wheel is essential for their nightly exercise routine.
Before bringing a hedgehog home, one must verify local laws, as they are illegal to keep as pets in certain regions.
In places where they are permitted, owners should familiarize themselves with the legal responsibilities, such as ensuring that the hedgehog is obtained from a licensed breeder and providing a habitat that meets the species’ needs.
Conservation Status
European hedgehogs, a different species from those typically kept as pets, are classified as vulnerable in certain habitats due to threats such as habitat loss and traffic accidents.
In recent studies, such as the one conducted in the Czech rescue centers, conservationists have observed significant intake and release trends for hedgehogs, emphasizing the importance of rehabilitating injured individuals and addressing the causes of their decline Trends in intake and outcomes for European hedgehog (Erinaceus europaeus) in the Czech rescue centers.
Active conservation efforts are crucial for protecting these species and maintaining ecological balance.
The public can aid these efforts by creating wildlife-friendly gardens that provide natural shelter food sources for hedgehogs.
Interested individuals should consult local wildlife organizations to get involved or gather more information on supporting hedgehog populations.
