Amur Hedgehog (Erinaceus amurensis) lives in temperate forests across Northeast Asia. It feeds on insects and fruits. Its conservation status is Least Concern.
Fascinating facts about the Amur Hedgehog
- The Amur hedgehog hunts at night, relying on its keen sense of smell and acute hearing to detect insects and other tiny prey. It moves through grassland and forest edges while listening for the faint rustle of earthworms or the scent of fly larvae. As it searches, it emits the characteristic pig-like grunts that gave the group its common name. These nocturnal forays allow it to exploit food sources that are less active by day.
- The Amur hedgehog's coat is covered with long, sharp spines that appear in two colour forms: some are plain white, while others have a white or yellowish-brown base and tip with a dark brown centre. This mixture gives the animal a pale brownish-grey overall look. Adults measure between 160 mm and 290 mm in head-and-body length and weigh from 600 g to 1 000 g, making them slightly larger than their European relatives.
- As winter approaches, the Amur hedgehog enters a torpid state around October, reducing its metabolic rate to conserve energy. It remains in this hibernation throughout the cold months, only awakening when spring temperatures rise. This seasonal dormancy aligns with the animal's need to avoid the scarcity of food and the harsh conditions of its lowland and valley habitats. Emerging in spring, it resumes nocturnal foraging to rebuild its reserves.
- In captivity the Amur hedgehog typically reaches about eight years of age, a figure that reflects the lifespan of individuals kept under human care. This contrasts with the uncertainty surrounding its longevity in the wild, where no reliable data exist. The species is nevertheless classified as common and faces no identified specific threats, allowing stable populations across its range.
- Chinese sources claim that the Amur hedgehog falls prey to the sable (Martes zibellina), while Russian sources dispute this. The hedgehog inhabits lowland habitats such as grasslands, forest edges and mixed woodlands.
