### Physical Characteristics
Let’s take a close look at the physical details that make the European hedgehog such a unique creature.
#### Description:
European hedgehogs are small, rounded mammals covered in sharp spines (quills), which provide their primary defence against predators. Though slow-moving, their spines give them remarkable protection, making them less vulnerable in the wild.
#### Size:
##### Length:
– Average length: 20-30 cm (8-12 inches).
– Maximum length: Rare individuals may reach up to 35 cm (14 inches).
##### Weight:
– Average weight: Between 700-1,500 grams (1.5-3.3 pounds).
– Maximum weight: Can reach up to 2 kg (4.4 pounds) pre-hibernation.
##### Largest size found:
Hedgehogs over 2 kg have been recorded, primarily in captivity or before hibernation.
##### Smallest size found:
Newborn hedgehogs (hoglets) can weigh under 25 grams (0.05 pounds).
#### Body and Coloration:
European hedgehogs have a wide, rounded body with a dense covering of sharp spines across their back and sides. They can have between 5,000 and 7,000 spines, which are each around 2-3 cm long. Beneath, the belly and face are soft and covered in a mix of brown and white fur. Spines are usually brown with white tips, offering camouflage in undergrowth habitats.
#### Distribution:
The European hedgehog is predominantly found across much of Europe, from the UK to Western Russia, mainly in temperate areas. They are also found in countries like France, Germany, Italy, Norway, and parts of Scandinavia. They thrive in woodlands, grasslands, and suburban gardens as well.

### Habitat and Behaviour
These nocturnal animals are adaptable, but their behaviour and habitat preferences are quite specific to their survival.
#### Habitat:
European hedgehogs prefer dense, vegetated areas such as woodlands, grasslands, and hedgerows. They also frequently inhabit suburban gardens, parks, and farmlands where they can forage for food under cover. They require varied environments that provide ample food sources and shelter.
#### Diet:
Primarily insectivorous, European hedgehogs feed on beetles, caterpillars, worms, and slugs. On occasion, they will consume small vertebrates like frogs or even bird eggs. They are commonly described as opportunistic feeders, as they adapt their diet based on seasonal availability.
#### Behaviour:
Hedgehogs are solitary creatures and predominantly nocturnal, emerging at dusk to forage for food. If threatened, European hedgehogs will roll into a tight ball, exposing only their sharp spines. Communication between hedgehogs is primarily vocal, with an array of snorts, squeals, and growls used to display emotions or intentions.
#### Lifespan:
In the wild, hedgehogs generally live between 2-5 years due to predation and environmental hazards. In captivity, they may live up to 8-10 years with fewer threats.
#### Reproduction and Life Cycle:
Breeding season occurs in late spring or early summer. Mating usually happens after a brief ‘courtship’ chase, with the male circling the female. Females give birth to an average litter of 4-5 hoglets. These young are initially blind and spineless, but within a few weeks, they develop spines, wean, and become independent.
#### Predators:
While the hedgehog’s spine is a powerful defence, they are still prey to larger animals. Common predators include badgers, foxes, birds of prey, and dogs. Badgers are among their most dangerous adversaries.
#### Adaptations:
One of their primary adaptations is hibernation during the colder months when food becomes scarce. During hibernation, a hedgehog’s body temperature can drop dramatically, and their metabolism slows down to conserve energy. Their spines provide a formidable defence from most predators, allowing them to blend into their environment.
#### Relationship with humans:
Historically, hedgehogs have had a favourable relationship with humans, often seen as beneficial animals in gardens thanks to their appetite for pests like slugs. However, modern challenges, such as road networks and habitat destruction, have made them increasingly vulnerable in human-dominated landscapes.

### Conservation Status
As human impact on their environment grows, understanding their conservation status becomes vital.
#### Conservation Status:
According to the IUCN Red List, the European hedgehog is classified as “Least Concern,” but populations are in decline, particularly in the UK where they are a species of priority conservation.
#### Threats:
a) Habitat loss from modern agricultural practices and development projects.
b) Pesticides reduce the availability of their insect prey.
c) Urbanisation leads to ‘fragmented habitats,’ and roads present a significant danger.
#### Conservation Efforts:
Various conservation programmes aim to protect hedgehogs. In the UK, campaigns like “Hedgehog Street” encourage homeowners to make gardens more accessible through “hedgehog highways.” National bodies and local groups also monitor population changes and advocate for safer roadways and hedgehog-friendly gardens.

### Additional Fields
#### Interesting Facts:
– European hedgehogs typically roam around 1-2 km every night in search of food.
– They can have up to 44 teeth designed to crush and grind their prey.
– A hedgehog’s spines are made from keratin, the same material found in human hair and nails.
#### Cultural Significance:
In many European traditions, the hedgehog symbolises warmth, protection, and perseverance. It features in Eastern European folklore as a wise creature, often guiding other animals or humans.
#### Economic Importance:
Hedgehogs play a pivotal role in gardens and ecosystems by controlling insect populations. They also contribute to the health of the soil through their constant foraging and digging.
#### Threats and Conservation Efforts:
Fragmentation of their habitats remains one of the most significant threats. Creating awareness at the community level and establishing environment-friendly zones are essential steps for their long-term conservation.

### FAQs
**1. Are European hedgehogs dangerous to humans?**
No, European hedgehogs are not dangerous to humans. Their quills are used solely for defence, and they pose no threat unless mishandled.
**2. What should I feed a hedgehog in my garden?**
You can offer prepared hedgehog food, dog or cat food, or even mealworms and chopped fruits. Avoid milk and bread, as these can disrupt their digestion.
**3. How can I make my garden more hedgehog-friendly?**
You can create ‘hedgehog highways’ with small gaps in fences, plant hedgerows, and cultivate bushes or leaves to provide food and shelter. Avoid using pesticides.
**4. How often do European hedgehogs hibernate?**
European hedgehogs hibernate every year, usually from November to March, depending on climate and food availability.
