Eulypotyphla
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] |
Lipotyphla
Lipotyphla is a formerly used order of mammals, including the members of the order Eulipotyphla (i.e. the solenodons, family Solenodontidae; hedgehogs and gymnures, family Erinaceidae; desmans, moles, and shrew-like moles, family Talpidae; and true shrews, family Soricidae) as well as three other families of the former order Insectivora, Chrysochloridae (golden moles), Tenrecidae (tenrecs), and Potamogalidae (otter shrews). However, molecular studies found the golden moles, tenrecs, and otter shrews to be unrelated to the others (these afrothere groups were then put in their own order, Afrosoricida). This made Lipotyphla an invalid polyphyletic order and gave rise to the notion of Eulypotyphla 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 afr ... instead, an exclusively laurasiather ...

Hispaniolan Solenodon
The Hispaniolan solenodon (''Solenodon paradoxus'') is a small, furry, shrew-like mammal endemic to the Caribbean island of Hispaniola (in the Dominican Republic and Haiti). Like other solenodons, it is a venomous, insect-eating animal that lives in burrows and is active at night. It is an elusive animal and was only first described in 1833; its numbers are stable in protected forests but it remains the focus of conservation efforts. Its smaller sister species of the same genus, Marcano's solenodon (''S. marconoi'') became extinct after European colonization. The Hispaniolan solenodon and the rat-like Hispaniolan hutia live in the same habitats and are the only surviving mammals native to the island. Discovery In 1833 the Russian Academy of Sciences received a new specimen from Haiti. Puzzled by the animal, curator Johann Friedrich von Brandt named it ''Solenodon paradoxus''. (''Solenodon'' means "grooved teeth".) No more information was known other than a relation to the Cuban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laurasiatheria
Laurasiatheria ("laurasian beasts") is a superorder of placental mammals that groups together true insectivores ( eulipotyphlans), bats ( chiropterans), carnivorans, pangolins ( pholidotes), even-toed ungulates (artiodactyls), odd-toed ungulates (perissodactyls), and all their extinct relatives. From systematics and phylogenetic perspectives, it is subdivided into order Eulipotyphla and clade Scrotifera. It is a sister group to Euarchontoglires with which it forms the magnorder Boreoeutheria. Laurasiatheria was discovered on the basis of the similar gene sequences shared by the mammals belonging to it; no anatomical features have yet been found that unite the group. The Laurasiatheria clade is based on DNA sequence analyses and retrotransposon presence/absence data. The superorder originated on the northern supercontinent of Laurasia, after it split from Gondwana when Pangaea broke up. Its last common ancestor is supposed to have diversified ca. 76 to 90 million years ago. Ety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Shrew
Shrews (family Soricidae) are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders. Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles; shrews are related to rodents only in that both belong to the Boreoeutheria magnorder. Shrews have sharp, spike-like teeth, whereas rodents have gnawing front incisor teeth. Shrews are distributed almost worldwide; among the major tropical and temperate land masses, only New Guinea, Australia, and New Zealand have no native shrews; in South America shrews appeared only relatively recently, as a result of the Great American Interchange, and are present only in the northern Andes. The shrew family has 385 known species, making it the fourth-most spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrew Mole (''Neurotrichus gibbsii'')
...
A shrew mole or shrew-mole is a mole that resembles a shrew. Species with this name include: * Five species in the subfamily Uropsilinae, or "shrew-like moles", native to China: ** Equivalent teeth shrew mole (''Uropsilus aequodonenia'') ** Anderson's shrew mole (''Uropsilus andersoni'') ** Gracile shrew mole (''Uropsilus gracilis'') ** Inquisitive shrew mole (''Uropsilus investigator'') ** Chinese shrew mole (''Uropsilus soricipes'') * Two species in the tribe Urotrichini, or ''himizu'', native to Japan: ** Japanese shrew mole (''Urotrichus talpoides'') ** True's shrew mole (''Dymecodon pilirostris'') * One species in the tribe Neurotrichini, native to Pacific North America: ** American shrew mole The American shrew mole (''Neurotrichus gibbsii'') is the smallest species of mole. It is the only living member of the genus ''Neurotrichus'' and the tribe Neurotrichini. It is also known as Gibb's shrew mole and least shrew mole. It is not c ...

Mole (animal)
Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. The word “mole” refers to any species in the family Talpidae, which means “mole” in Latin. Moles are found in most parts of North America, Europe and Asia. Moles may be viewed as pests to gardeners, but they provide positive contributions to soil, gardens, and ecosystem, including soil aeration, feeding on slugs and small creatures that eat plant roots, and providing prey for other wildlife. They eat earthworms and other small invertebrates in the soil. Terminology In Middle English, moles were known as ''moldwarp''. The expression "don't make a mountain out of a molehill" (which means "exaggerating problems") was first recorded in Tudor times. By the era of Early Modern English, the mole was also known in English as ''mouldywarp'', a wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desman
The desman, a snouted and naked-tailed diving insectivore of the tribe Desmanini (also considered a subfamily, Desmaninae), belongs to one of two Eurasian species of the mole family, Talpidae. This tribe consists of two monotypic genera of semiaquatic insectivores found in Europe: one in Russia and the other in the northwest of the Iberian peninsula and Pyrenees. Both species are considered to be vulnerable. They have webbed paws and their front paws are not well-adapted for digging. Desmans were much more diverse and widespread during the Miocene, with one genus, ''Gaillardia'', being present in North America. Both living species are thought to have derived from the fossil genus '' Archaeodesmana.'' The list of species is: *Genus ''Desmana'' **Russian desman (''D. moschata'') *Genus ''Galemys'' **Pyrenean desman (''G. pyrenaicus'') * Genus †'' Archaeodesmana'' Miocene-Pliocene, Europe * Genus †''Gaillardia'' Miocene, North America * Genus †'' Mygalinia'' Late Miocene, H ...

Solenodon
Solenodons (from el, τέλειος , 'channel' or 'pipe' and el, ὀδούς , 'tooth') are venomous, nocturnal, burrowing, insectivorous mammals belonging to the family Solenodontidae . The two living solenodon species are the Cuban solenodon (''Atopogale cubana''), and the Hispaniolan solenodon (''Solenodon paradoxus''). Threats to both species include habitat destruction and predation by non-native cats, dogs, and mongooses, introduced by humans to the solenodons' home islands to control snakes and rodents. The Hispaniolan solenodon covers a wide range of habitats on the island of Hispaniola from lowland dry forest to highland pine forest. Two other described species became extinct during the Quaternary. Oligocene North American genera, such as '' Apternodus'', have been suggested as relatives of ''Solenodon'', but the origins of the animal remain obscure. Two genera, '' Atopogale'' and ''Solenodon'', are known, each with one extant species. Other genera have been ere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erinaceomorpha
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 ...

Gymnure
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedgehog
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'' ...
