Oryzorictinae
Oryzorictinae is a subfamily of tenrecs endemic to the island of Madagascar. It is the largest of three tenrec subfamilies. Oryzorictinae is thought to have split from the lineage of its closest relative, ''Geogale'', about 30 million years ( Ma) ago. The deepest phylogenetic split within the subfamily, that between '' Oryzorictes'' and a clade composed of ''Microgale'' plus ''Nesogale'' , is thought to have occurred about 28 Ma ago. In turn, ''Microgale'' and ''Nesogale'' are thought to have diverged about 19 Ma ago.

Web-footed Tenrec
The web-footed tenrec, Malagasy otter shrew, or aquatic tenrec (''Microgale mergulus'') is the only known semiaquatic tenrec (the related African otter shrews have similar habits), and is found in eastern Madagascar, especially in and around Ranomafana National Park. It grows to between , and was once thought to be extinct. It feeds on crabs, aquatic insects, and crayfish. The population is considered vulnerable. It was formerly placed in the Monotypic taxon, monotypic genus ''Limnogale'', but has been moved to ''Microgale'' based on molecular data showing it to be deeply nested within the latter. Life history ''Microgale mergulus'' is strictly nocturnal, spending the day in stream side burrows, only emerging at night to hunt. Nocturnal movements appear to be restricted to waterways but include movements away from burrows and diving. Radio collar tracking has shown that some individuals are known to utilize stream channels as much as 1160 meters in length, while others may only ...

Geogale
The large-eared tenrec (''Geogale aurita'') is a species of mammal in the family Tenrecidae. It is the only species in the monotypic genus ''Geogale'', and the only member of the subfamily Geogalinae. It is endemic to Madagascar where its natural habitats are subtropical or tropical dry forests and shrubland. It is threatened by habitat loss, but to a lesser extent than was previously thought and is listed by the IUCN as being of "Least Concern". ''Geogale'' is thought to have split from the ancestors of its sister clade, the subfamily Oryzorictinae, about 30 million years ago. Description The large-eared tenrec is a small shrew-like animal with short, soft fur, a long hairy tail and large projecting ears. Adults weigh between and measure in length, with a tail half as long again. The dorsal (upper) surface is greyish brown or reddish brown and the ventral (under) surface is buffish white. The large-eared tenrec differs from other tenrecs in the family by having 34 teeth inste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jenkins's Shrew Tenrec
Jenkins's shrew tenrec (''Microgale jenkinsae'') is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests and shrubland. It is threatened by habitat loss. Description Jenkins's shrew tenrec is extremely small, 143-147mm with the tail being 71-81mm . Its fur is extremely dense, with the top of it being tannish-brown with darker flecks from their agouti gene. On the bottom it is a paler grizzled slate-gray. The tail of this Tenrec is dark brown on the top, and much lighter on the bottom. Habitat This tenrec is restricted to the Mikea Forest between Morombe and Manobo River in Southwest Madagascar. It is generally found in forest habitats. The forest of this region grows on sandy soil and in a semi-arid climate with annual precipitation as low as 350 mm. The canopy, which rarely exceeds twelve meters in height, is less tall than that of the inland forests and of those further north. Its habitat e ...

Nesogale
''Nesogale'' is a genus of tenrecs, which are a family of afrotherian mammals endemic to Madagascar. On the basis of molecular data indicating its two species form a sister group to the rest of ''Microgale'' (21 extant species), they were transferred from ''Microgale'' to ''Nesogale'' in 2016, thus resurrecting a genus first erected by Oldfield Thomas in 1918. These genera, along with '' Oryzorictes'', form the tenrec subfamily Oryzorictinae. ''Nesogale'' contains the following species: * Dobson's shrew tenrec (''N. dobsoni'') - (Thomas, 1884) * Talazac's shrew tenrec (''N. talazaci'') - (Major, 1896) These species are distinguished from the other shrew tenrecs of ''Microgale'' by being more robust and larger, and by their lack of premolar diastemata. They are distributed over much of the eastern and northern areas of the island. ''Nesogale'' and ''Microgale'' are estimated to have split during the Early Miocene The Early Miocene (also known as Lower Miocene) is a sub-epoch of ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Northern Shrew Tenrec
The northern shrew tenrec (''Microgale jobihely'') is a species of mammal in the family Tenrecidae. It is endemic to Madagascar, where it has a restricted disjoint range in two locations 485 km apart in the north and east of the island. In the north, it is found on the southwestern slopes of the Tsaratanana Massif at elevations from 1420 to 1680 m. In central eastern Madagascar, it is found in the Ambatovy Forest. Its natural habitat is montane forest. The species is most closely related to the widely distributed ''M. cowani''. This tenrec is threatened by deforestation from agricultural conversion, lumbering and mining Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic via .... References Afrosoricida Mammals of Madagascar Mammals described in 2006 {{afrosoricida-stu ...
