Eulipotyphla
Eulipotyphla (, from '' eu-'' + '' Lipotyphla'', meaning truly lacking blind gut; sometimes called true insectivores) is an order of mammals comprising the Erinaceidae ( hedgehogs and gymnures); Solenodontidae (solenodons); Talpidae ( moles, shrew-like moles and desmans); and Soricidae (true shrews) families. Taxonomic history Historically, these animals were grouped with others such as treeshrews, elephant shrews, and colugos, under the broader category Insectivora, comprising all small insect-eating placental mammals. Wilhelm Peters identified two sub-groups of Insectivora, distinguished by the presence or absence of a cecum in the large intestine. In his 1866 ''Generelle morphologie der organismen'', Ernst Haeckel named these groups Menotyphla and Lipotyphla, respectively from ''μένω'' ("remain")/''λείπω'' ("lack" or "leave behind") + ''τυφλὸν'' literally "blind", as in ''τυφλὸν ἔντερον'' ("blind intestine", from which the Latin '' ...

Insectivora
The Order (biology), 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 Basal (phylogenetics), basal clades of placental mammals. History Before the era of widespread DNA sequencing, the grouping was used as a Polyphyly, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 both Soricidae and Talpidae share a more recent common ancestor with Erinaceidae than with solenodons. Erinaceidae contains the well-known hedgehogs (subfamily Erinaceinae) of Eurasia and Africa and the gymnures or moonrats (subfamily Galericinae) of Southeast 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 ...

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, and 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] |
Mammals
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nyctitheriidae
Nyctitheriidae is a family of extinct eulipotyphlan insectivores known from the Paleocene and Eocene Epoch, epochs of North America and Asia and persisting into the Oligocene of Europe. Several genera, including ''Nyctitherium'', ''Paradoxonycteris'', and ''Wyonycteris'', have initially been described as Bat, bats, although the family is more frequently placed in the order Eulipotyphla. Origins and discovery Othniel Charles Marsh, O.C. Marsh originally described ''Nyctitherium'', from the Eocene of Wyoming, as an early bat based on similarities of its teeth. Since 1872 more than two dozen other genera of nyctitheriids have been named, and several of these have also initially been considered bats. George Gaylord Simpson, G.G. Simpson recognized that ''Nyctitherium'' did not represent a bat, and in 1928 named the family Nyctitheriidae for ''Nyctitherium'' and several other small insectivores. Many additional species of Nyctitheriidae from Asia, Europe, and North America have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solenodon
Solenodons (from , 'channel' or 'pipe' and , '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 period. Oligocene North American genera, such as '' Apternodus'', have been suggested as relatives of ''Solenodon'', but the origins of the animal remain obscure. Taxonomy Two genera, '' Atopogale'' and '' Solenodon'', are known, each with one extant species. Other genera have been erected, but ar ...

Lipotyphla
Lipotyphla is a formerly used order of mammals, meaning lacking blind gut, 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 Eulipotyphla Eulipotyphla (, from '' eu-'' + '' Lipotyphla'', meaning truly lacking blind gut; sometimes called true insectivores) is an order of mammals comprising the Erinaceidae ( hedgehogs and gymnures); Solenodontidae (solenodons); Talpidae ( mole ... instea ...

Talpidae
The family (biology), family Talpidae () includes the true Mole (animal), moles (as well as the shrew moles and desmans) who are small insectivore, insectivorous mammals of the order (biology), order Eulipotyphla. Talpids are all fossorial, digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere of Eurasia and North America (although none are found in Ireland nor in the Americas south of northern Mexico), and range as far south as the Montane ecosystems, montane regions of tropical Southeast Asia. The first talpids evolved from shrew-like animals which adapted to digging late in the Eocene in Europe. ''Eotalpa, Eotalpa anglica'' is the oldest known mole, it was discovered in the Late Eocene deposits of Ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Mole
The European mole (''Talpa europaea'') is a mammal of the order Eulipotyphla. It is also known as the common mole and the northern mole. This mole lives in a tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions, the displaced earth is pushed to the surface, resulting in the characteristic molehills. It is an omnivore that feeds mainly on earthworms, but also on insects, centipedes and mammals such as rodents and other moles. Its saliva contains toxins which paralyze earthworms in particular. Taxonomy The Aquitanian mole (''T. aquitania'') was formerly considered conspecific, but was described as a distinct species in 2017. Distribution The European mole has a wide range throughout Europe and westernmost Asia, being found as far north as the United Kingdom and southern Scandinavia, as far south as northern Greece, and as far east as western Siberia. It is the only mole species in most of this range. The Loire River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphilemuridae
The Amphilemuridae are a family of extinct mammals belonging to the order Eulipotyphla, from the Eocene of Europe and North America. Description Amphilemurids were generally small in size and may have resembled moonrats in life. Some species had spines like those of hedgehogs, while others were almost free of spines or had bristly coats. Most species are known only from teeth. Classification The family Amphilemuridae was first described in 1953 by Hill, and was included in the order Insectivora, which later proved to be polyphyletic. Currently the amphilemurids are considered basal members of the order Eulipotyphla, although Hooker and Russell (2012) considered them to belong to the order Macroscelidea.

Nesophontidae
''Nesophontes'', sometimes called West Indies shrews, is the sole genus of the extinct, monotypic mammal family Nesophontidae in the order Eulipotyphla. These animals were small insectivores, about 5 to 15 cm long, with a long slender snout and head and a long tail. They were endemic to the Greater Antilles (except Jamaica), in Cuba, Hispaniola (now the Dominican Republic and Haiti), Puerto Rico, the United States Virgin Islands, and the Cayman Islands. Extinction Although reliable estimates are unavailable, these animals are confirmed to have survived the Pleistocene extinction, since remains have been found among those of ''Rattus'' and '' Mus'' species. Some authorities estimate extinction coinciding with the arrival of rats aboard Spanish vessels in the early 16th century (1500). Others, such as Morgan and Woods, claim that some species survived until the early 20th century. A phylogenetic study in 2016, based on DNA extracted from a specimen about 750 years old, suggest ...
