This hedgehog is closely related to and slightly larger and lighter in color than the European hedgehog, with a head and body length of between and a very short tail. It weighs between 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 quills on the head are separated from each other by narrow strips of bare skin. The quills, covered in keratin, are strong so that they don't break or fall out. These spines are used as a defense mechanism when they are threatened. The hedgehog curls up into a ball, where their quills are facing out and their face/head are curled inwards. The face and underparts are covered in pale hair.

The Amur hedgehog is found natively 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. There is no information regarding this specific species reproduction to this date.

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.

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". These hedgehogs, though common, have a lifespan of 8 years, while in captivity. It is unknown how long they live in native lands.
