Characteristics

Erinaceids are generally shrew-like in form, with long snouts and short tails. They are, however, much larger than shrews, ranging from 10-15 cm in body length and 40-60 grams in weight, in the case of the Short-tailed Gymnure, up to 26-45 cm and 1-1. The Short-tailed Gymnure ( Hylomys suillus) is a small Erinaceomorph that is found in southeast Asia. 4 kilograms in the Greater 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. All species have anal scent glands, but these are far better developed in gymnures, which can have a powerful odor[2]. Scent glands are found in the genital area of most Mammals and in various other parts of the body such as the underarms of Humans and the Preorbital

Erinaceids are omnivorous, with the major part of their diet consisting of insects, earthworms, and other small invertebrates. Omnivores (from Latin omne all everything vorare to devour are species that eat both Plants and Animals as their primary They also eat seeds and fruit, and occasionally bird's eggs, along with any carrion they come across. Their teeth are sharp and suited for impaling invertebrate prey. The dental formula for erinaceids is:

2-3. Dentition is the development of Teeth and their arrangement in the Mouth. 1. 4-4. 3
3. 1. 2-4. 3

Hedgehogs are nocturnal, but gymnures are less so, and may be active during the day. As an Animal behavior, nocturnality describes sleeping during the Daytime and being active at Night - the opposite of the diurnal 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[2].

Female erinaceids give birth 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.

Evolution

Erinaceids are a relatively primitive group of placental mammals, having changed little since their origin in the Eocene. See also Evolution of mammals Eutheria ("true beast" are a group of Mammals consisting of Placental mammals plus all extinct Mammals The Eocene epoch (558 ± 02 - 339 ± 01 Ma) is a major division of the Geologic timescale and the second epoch of the Palaeogene period in The so-called 'giant hedgehog' (actually a gymnure) Deinogalerix, from the Miocene of Italy, was the size of a large rabbit, and may have eaten vertebrate prey or carrion, rather than insects[3]. Deinogalerix (from Ancient Greek, "terrible/terror" + "shrew" was a Genus of the order Erinaceomorpha, which lived The Miocene is a geological epoch of the Neogene period and extends from about 23 Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest

Classification

There are 10 genera and 24 species of erinaceid.
