Erinaceidae

Erinaceids are generally shrew-like in form, with long snouts and short tails. They are, however, much larger than shrews, ranging from {{convert|10|–|15|cm|0|abbr=on}} in body length and {{convert|40|-|60|g}} in weight, in the case of the short-tailed gymnure, up to {{convert|26|–|45|cm|0|abbr=on}} and {{convert|1.0|-|1.4|kg|abbr=on}} in the moonrat. All but one species have five toes in each foot, in some cases with strong claws for digging, and they have large eyes and ears. Hedgehogs possess hair modified into sharp spines to form a protective covering over the upper body and flanks, while gymnures have only normal hair. Most species have anal scent glands, but these are far better developed in gymnures, which can have a powerful odor.{{cite book|editor-last= Macdonald|editor-first= D.|last= Wroot|first= Andrew|year= 1984|title= The Encyclopedia of Mammals|publisher= Facts on File|location= New York|pages= [https://archive.org/details/encyclopediaofma00mals_0/page/750 750–757]|isbn= 0-87196-871-1|url-access= registration|url= https://archive.org/details/encyclopediaofma00mals_0/page/750}}

Erinaceids are omnivorous, with the major part of their diet consisting of insects, earthworms, and other small invertebrates. They also eat seeds and fruit, and occasionally birds' eggs, along with any carrion they come across. Their teeth are sharp and suited for impaling invertebrate prey. The dental formula for erinaceids is: {{DentalFormula|upper=2-3.1.4.3|lower=3.1.2-4.3}}

Hedgehogs are nocturnal, but gymnures are less so, and may be active during the day. Many species live in simple burrows, while others construct temporary nests on the surface from leaves and grass, or shelter in hollow logs or similar hiding places. Erinaceids are solitary animals outside the breeding season, and the father plays no role in raising the young.

Female erinaceids give birth after a gestation period of around six to seven weeks. The young are born blind and hairless, although hedgehogs begin to sprout their spines within 36 hours of birth.

Erinaceids are a group of placental mammals that have retained many of their ancestral traits, having changed little since their origin in the Eocene. The so-called 'giant hedgehog' (actually a gymnure) Deinogalerix, from the Miocene of Gargano Island (part of modern Italy), was the size of a large rabbit, and may have eaten vertebrate prey or carrion, rather than insects.{{cite book |author1=Savage, RJG |author2= Long, MR |name-list-style=amp |year=1986 |title= Mammal Evolution: an illustrated guide|url=https://archive.org/details/mammalevolutioni0000sava |url-access=registration |publisher= Facts on File|location=New York|pages= [https://archive.org/details/mammalevolutioni0000sava/page/48 48–49]|isbn= 0-8160-1194-X}}
