Hedgehog Facts – Animals Of The World

The hedgehog is an unusual creature that has long attracted people’s interest. The creature has a long history of contact with people, and some tribes have taken advantage of it and utilized it as a pet, food source, and medicine.

The five genera, Atelerix, Erinaceus, Hemiechinus, Mesechinus, and Paraechinus, include seventeen distinct species of hedgehog. Scientific study has been done on the hedgehog.

Body Description

Hedgehogs are little rodent-like mammals that closely resemble porcupines. Like porcupine spikes but more securely connected to the body, the hedgehog’s upper body is covered with them. Keratin makes up the spikes. Soft hair covers the head, legs, and underbelly.

The hedgehog is characterized by a narrow snout, conical face, and dark, beady eyes. The hedgehog may have up to 44 teeth in its mouth. Despite having tiny legs, the forelegs are longer than the rear legs.

Depending on the species, hedgehogs may reach lengths of 5 to 14 inches and weigh between 150 and 1584 grams.


An omnivorous mammal, the hedgehog eats various things, including insects, snails, snakes, frogs, grass roots, berries, toads, bird eggs, and other reptile species. Hedgehogs use their keen hearing and a strong sense of smell to find food since they have weak vision.

Hedgehogs’ poor feeding habits make them vulnerable to heart disease because they eat a lot of fat and sugar, which their slow metabolism prevents them from effectively using.

Range And Habitat

Where they are native, the hedgehog may be found in portions of Europe, Asia, and Africa. Additionally, they have been brought to Australia and New Zealand. Hedgehogs may thrive in various settings, including woods, deserts, scrublands, savannahs, and suburban areas.

Hedgehogs construct their nests from twigs, leaves, and other plant materials in their natural environments. They may also live in animal-made burrows. Hedgehogs may also dig their holes or live in rock crevices.

Hedgehog species may be found in various parts of the globe, where they are kept as pets due to more significant domestication.

Hedgehogs are a species of most minor concern according to the IUCN because of their relatively large population.

Hedgehogs are, however, preyed upon by several animals, including owls, mongooses, wolves, ferrets, badgers, and foxes. In regions where they have been introduced, there are no native predators.


Hedgehogs are nocturnal, solitary mammals. Most hedgehog species hunt at night to escape predators, while daytime activity has sometimes been seen.

Hedgehogs have special protection where they curl up into a ball and remain motionless when threatened. Their spikes deter the predator while guarding the softer parts of their body, such as their head, legs, and belly.

However, other desert animals fight the intrusive individual and only use the ball as a last resort.

Hedgehogs’ spikes may be released when assaulted, but unlike porcupine spikes, they are not venomous. Hedgehogs spread the foam on their spikes after biting and licking the source of a new fragrance in an apparent attempt to disguise themselves from predators.

Hedgehogs hibernate or aestivate to adapt to harsh settings, including deserts, frigid climates, or times of drought.
