The Amur hedgehog (Erinaceus amurensis) is a hedgehog similar to the European hedgehog in appearance and behaviour, although it is more lightly coloured. It is native to Amur Oblast and Primorye in Russia, Manchuria in China, and the Korean Peninsula. Like other hedgehogs, it uses scent and hearing while looking for prey, and the name "hedgehog" refers to the pig-like grunts it makes as it forages.[3]

Description[edit]

This hedgehog is closely related to and slightly larger than the European hedgehog, with a head-and-body length of between 160 and 290 mm (6 and 11 in) and a very short tail. It weighs between 600 and 1,000 g (21 and 35 oz). The head, back and sides are covered with long, sharp spines. These are of two different colours; some are plain white; others have a white or yellowish-brown base and tip, and a central portion that is mid to dark brown, giving the animal an altogether pale, brownish-grey colour. The spines on the head are separated from each other by narrow strips of bare skin. The face and underparts are covered in pale hair.[4]

Distribution and habitat[edit]

The Amur hedgehog is found in the Amur Oblast and Primorye in Russia, Manchuria in China, and the Korean Peninsula. Its range extends from about 29°N, which is just south of the Yangtze River northwards to the Amur Basin and the Korean Peninsula. It occupies a wide range of habitats including grassland, forest edges, and areas with mixed coniferous and broadleaf woodland. The IUCN Red List states that it is found in valleys and lowlands but not in highland regions or cultivated fields.[2] The Mammals of China disagrees, stating that suitable habitats include montane and sub-alpine terrain, steppe, shrublands, cultivated land, villages and city parks.[4]

Ecology[edit]

Like other hedgehogs, this is a nocturnal species, emerging at night to forage for small arthropods, especially fly larvae, and earthworms, centipedes, snails, mice, frogs and occasionally fruit. Chinese sources state that this hedgehog is preyed on by sable (Martes zibellina), but Russian sources dispute this. There are one or two litters in the summer, each consisting of four to six young, and in about October, the hedgehog enters a state of torpor and hibernates until spring.[2][3][4]

Status[edit]

E. amurensis is a common species and no specific threats have been identified, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".[2]
