Erinaceidae
Erinaceidae is a family in the order Eulipotyphla, consisting of the hedgehogs and moonrats. Until recently, it was assigned to the order Erinaceomorpha, which has been subsumed with the paraphyletic Soricomorpha into Eulipotyphla. Eulipotyphla has been shown to be monophyletic; Soricomorpha is paraphyletic because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs. Erinaceidae contains the well-known hedgehogs (subfamily Erinaceinae) of Eurasia and Africa and the gymnures or moonrats (subfamily Galericinae) of South-east Asia. This family was once considered part of the order Insectivora, but that polyphyletic order is now considered defunct. Characteristics Erinaceids are generally shrew-like in form, with long snouts and short tails. They are, however, much larger than shrews, ranging from in body length and in weight, in the case of the short-tailed gymnure, up to and in the moonrat. All but one species have five toes in eac ...

Eulipotyphla
Eulipotyphla (, which means "truly fat and blind") is an order of mammals suggested by molecular methods of phylogenetic reconstruction, which includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members (tenrecs, golden moles, and otter shrews, now in their own order Afrosoricida). Eulipotyphla comprises the hedgehogs and gymnures (family Erinaceidae, formerly also the order Erinaceomorpha), solenodons (family Solenodontidae), the desmans, moles, and shrew-like moles (family Talpidae) and true shrews (family Soricidae). True shrews, talpids and solenodons were formerly grouped in Soricomorpha; however, Soricomorpha has been found to be paraphyletic, since erinaceids are the sister group of shrews, and they are more closely linked to the Carnivora order; (such as cats, dogs, bears, skunks, badgers, etc.). It is the sister clade of Scrotifera; together, they make up Laurasiatheria. Classification * Order Eulipoty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insectivora
The order Insectivora (from Latin ''insectum'' "insect" and ''vorare'' "to eat") is a now-abandoned biological grouping within the class of mammals. Some species have now been moved out, leaving the remaining ones in the order Eulipotyphla, within the larger clade Laurasiatheria, which makes up one of the most basic clades of placental mammals. History Before the era of widespread DNA sequencing, the grouping was used as a polyphyletic taxon for a variety of small to very small, relatively unspecialised mammals that feed upon insects. Since any primitive-looking fossil group of placental mammals was commonly assigned to this order for convenience, it was held to constitute the basal stock out of which other placental orders had evolved. Therefore, at its widest extent, the order Insectivora represented an evolutionary grade rather than a clade. Taxonomy has been refined in recent years, and treeshrews, elephant shrews, and colugos have now been placed in separate orders, as ...

Echinosorex
The moonrat (''Echinosorex gymnura'') is a southeast Asian species of mammal in the family Erinaceidae (hedgehogs and gymnures). It is the only species in the genus ''Echinosorex''. The moonrat is a fairly small, primarily carnivorous animal which, despite its name, is not closely related to rats or other rodents. The scientific name is sometimes given as ''Echinosorex gymnurus'', but this is incorrect. Description The moonrat has a distinct pungent odor with strong ammonia content, different from the musky smell of carnivorans. There are two subspecies: ''E. g. gymnura'' is found in Sumatra and the Thai-Malay Peninsula; ''E. g. alba'' is found in Borneo. In the former the head and frontal half of the body are white or grey-white; the remaining is mainly black. The latter subspecies is generally white (''alba'' means white in Latin), with a sparse scattering of black hairs; it appears totally white from a distance. Those from western Borneo tend to have a greater proportion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galericinae
Gymnures, also called hairy hedgehogs or moonrats, are mammals belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla. Gymnures resemble rats but are not closely related as they are not rodents; they are instead closely related to hedgehogs, which also belong to Erinaceidae. They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews. Description Although the gymnures are more closely related to the hedgehogs, full-grown gymnures superficially resemble large rats, shrews or opossums. The gymnure's body plan is believed to resemble that of the earliest mammals, with a large, toothy head about 1/3 the length of the total body, a naked furless tail for balance and thermoregulatory purposes, and a plantigrade stance. In direct contrast to the closely related hedgehogs, gymnures are not spiny. They also have an out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hedgehogs
A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus '' Amphechinus'' was once present in North America. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last fifteen million years. Like many of the first mammals, they have adapted to a nocturnal way of life. Their spiny protection resembles that of porcupines, which are rodents, and echidnas, a type of monotreme. Etymology The name ''hedgehog'' came into use around the year 1450, derived from the Middle English ''heyghoge'', from ''heyg'', ''hegge'' ("hedge"), because it frequents hedgerows, and ''hoge'', ''hogge'' ("ho ...

Soricomorpha
Soricomorpha (from Greek "shrew-form") is a formerly used taxon within the class of mammals. In the past it formed a significant group within the former order Insectivora. However, Insectivora was shown to be polyphyletic and various new orders were split off from it, including Afrosoricida (tenrecs, golden moles, otter shrews), Macroscelidea (elephant shrews), and Erinaceomorpha (hedgehogs and gymnures), with the four remaining extant and recent families of Soricomorpha shown here then being treated as a separate order. Insectivora was left empty and disbanded. Subsequently, Soricomorpha itself was shown to be paraphyletic, because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs. The combination of Soricomorpha and Erinaceidae, referred to as order Eulipotyphla, has been shown to be monophyletic. Living members of the group range in size from the Etruscan shrew, at about 3.5 cm and 2 grams, to the Cuban solenodon, at about 32&n ...

Proterix
''Proterix'' is an extinct genus of hedgehog-like insectivore from the Late Oligocene to the Early Miocene of North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car .... Description ''Proterix'' was an armor-headed burrowing insectivore. Although it was speculated to be limbless in a popular science book, very little of the post-cranial skeleton has been found, which is typical for mammals. The original reference suggests reduced limbs may be possible, due to the unusually high number of lumbar vertebrae, but cautions that conclusions must be reserved until a complete skeleton is found.

Deinogalerix
''Deinogalerix'' (from Ancient Greek, "terrible/terror" + ''Galerix'') is an extinct genus of gymnure which lived in Italy in the Late Miocene, 7-10 million years ago. The genus was apparently endemic to what was then the island of Gargano, which is now a peninsula. The first specimens of ''Deinogalerix'' were first described in 1972. The genus is in the hedgehog subfamily of gymnures or moon-rats, which are not rats at all, but rather hairy, superficially rat-like relatives of the hedgehog lacking quills. ''Deinogalerix'' had a long, thin, conical face, small pointed ears, a lengthy, tapering tail and long hairs. ''Deinogalerix koenigswaldi''s skull was long and the entire body measured . It occupied the same ecological niche as dogs and cats today, except that it had more predators itself - such as the enormous barn owl '' Tyto gigantea''. It is believed that the species of ''Deinogalerix'' were insectivores, mostly feeding off invertebrates like beetles, dragonflies and ...

Silvacola
''Silvacola'' is an extinct genus of mammals belonging to the family Erinaceidae, which also contains the modern hedgehogs and gymnures. It lived in North America during the Early Eocene, about 50 million years ago. It was just long, roughly the length of an adult thumb. It is the smallest erinaceid ever found and comparable in size to some of today's shrews. The teeth suggest it was an omnivore that probably ate insects and plants it found on the forest floor. The fossil was discovered in the Driftwood Creek Beds near Smithers, British Columbia, about 670 kilometers north of Vancouver. It was once the site of an ancient lake, and it is a popular place to find fossils of early Eocene flora and fauna., part of the Eocene Okanagan Highlands The Eocene Okanagan Highlands or Eocene Okanogan Highlands are a series of Early Eocene geological formations which span a transect of British Columbia, Canada, and Washington state, United States.
