Four-toed Hedgehog (Atelerix albiventris) lives in open savanna across Sub-Saharan Africa. It feeds on insects and fruits. Its conservation status is Least Concern.
Fascinating facts about the Four-toed Hedgehog
- The four-toed hedgehog walks on just four toes on each hind foot, the hallux being absent, a trait that sets it apart from other hedgehogs. This reduction is noted in the species name and distinguishes it from related hedgehogs that retain a fifth toe. Occasionally an individual shows a small bony lump where the hallux would be, and in rare cases a rudimentary extra toe can develop on the hind foot.
- The four-toed hedgehog can eat highly venomous prey such as scorpions and snakes without ill effect, thanks to its unusually high tolerance for toxins. It regularly hunts at night, covering large distances while foraging for insects, grubs, snails, spiders, plant matter and small vertebrates, and it will seize scorpions or venomous snakes when encountered. This toxin resistance lets it exploit food sources that many other predators avoid.
- In captivity some four-toed hedgehogs have been claimed to run more than 8 km in a single night, with sprint bursts over 16 km/h. Owners often provide a large running wheel, and because captive animals live in temperature-controlled environments they rarely enter aestivation or hibernation.
- When it encounters a strong new odour, the four-toed hedgehog mixes the scent with its saliva to create a copious foam that it spreads over its spines. This self-anointing behaviour produces a large amount of frothy coating that covers the animal's quills. Researchers think the foam may serve a defensive purpose, as the species has been observed applying it after handling poisonous toads.
- In the wild a four-toed hedgehog rarely survives beyond about three years, reflecting the pressures of predation and environmental stress. Under human care, however, individuals have been recorded living up to ten years, a dramatic increase that highlights the benefits of protected conditions and regular feeding. Captive hedgehogs also tend to reach a typical lifespan of four to six years, far longer than their wild counterparts.

About the Four-toed Hedgehog
In the scorching savannas and grasslands, the four-toed hedgehog emerges under the cloak of darkness, its peculiar gait a testament to its unique character. As it moves through the underbrush, its spiny coat glistens like a mesh of tiny, barbed stars, a remarkable defense mechanism that protects it from predators, while its powerful claws and agile limbs allow it to forage with purpose. With an air of quiet determination, this small, yet formidable creature navigates its world, a true marvel of adaptation in the harsh, sun-baked landscapes it calls home.
