A tenrec is any species of mammal within the afrotherian family Tenrecidae, which is endemic to Madagascar. Tenrecs are a very diverse group; as a result of convergent evolution some resemble hedgehogs, shrews, opossums, rats, and mice. They occupy aquatic, arboreal, terrestrial, and fossorial environments. Some of these species including the greater hedgehog tenrec, can be found in the Madagascar dry deciduous forests. However, the speciation rate in this group has been higher in humid forests.
Microgale is a genus of mammal in the family Tenrecidae. There are 21 living species on the island of Madagascar and one extinct species known from a fossil. Some species have been discovered in the last twenty years.
Cowan's shrew tenrec is a species of mammal in the family Tenrecidae.
Dobson's shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist forests, plantations, and heavily degraded former forest. On the basis of molecular data indicating that it and Talazac's shrew tenrec form a sister group to the rest of Microgale, these two species were transferred from Microgale to Nesogale in 2016.
Drouhard's shrew tenrec, also known as the striped shrew tenrec, is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical and tropical moist lowland and montane forests.
The dryad shrew tenrec, also known as the tree shrew tenrec, is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist lowland forests.
The pale shrew tenrec, also known as the pale-footed shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical and tropical moist lowland and montane forests.
The gracile shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist montane forests.
The naked-nosed shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical and tropical moist lowland and monaten forests.
The montane shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist montane forests.
Nasolo's shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist montane and dry forests.
The least shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist forests, swamps, pastureland, and irrigated land.
The shrew-toothed shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist forests.
The taiva shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist forests.
Talazac's shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist forests. On the basis of molecular data indicating that it and Dobson's shrew tenrec form a sister group to the rest of Microgale, these two species were transferred from Microgale to Nesogale in 2016.
Thomas's shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist lowland forests.
Microgale macpheei is an extinct shrew tenrec from southeastern Madagascar. It is known only from two partial skulls found in Andrahomana cave, which radiocarbon dating of associated rodent remains suggests are about 3000 years old. It is the only known recently extinct tenrec. First described in 2007, it is most similar to the smaller Microgale brevicaudata of northern and western Madagascar. M. macpheei has a broad rostrum and, like M. brevicaudata, lacks a diastema (gap) between the premolars. A number of details of tooth morphology are characteristic of M. macpheei.
Microgale grandidieri, also known as Grandidier's shrew tenrec, is a species of shrew tenrec occurring in the dry forests of western and southwestern Madagascar. Populations of this species were formerly included in Microgale brevicaudata; M. grandidieri was described as a separate species in 2009 based on differences in morphology and DNA sequences.
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.
