The clade Tenrecoidea or Afrosoricida contains the golden moles of Southern Africa, the otter shrews of equatorial Africa and the tenrecs of Madagascar. These three groups of small mammals were for most of the 19th and 20th centuries regarded as a part of the Insectivora or Lipotyphla. Both groups, as traditionally used, are polyphyletic.
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.
The lowland streaked tenrec is a small tenrec found in Madagascar. It belongs to the family Tenrecidae in the order Afrosoricida, and more specifically to the subfamily of the spiny tenrecs Tenrecinae. Its natural habitats are in tropical lowland rain forests in northern and eastern parts of Madagascar.
The tailless tenrec, also known as the common tenrec, is a species of mammal in the family Tenrecidae. It is the only member of the genus Tenrec. Native to Madagascar, it is also found in the Comoros, Mauritius, Réunion, and Seychelles, where it has been introduced. Its natural habitats are subtropical or tropical forest, grassland, and shrubland, savanna, arable land, pastures, plantations, rural gardens, and urban areas.
The black-crowned sparrow-lark is a species of lark in the family Alaudidae. It is found across northern Africa from Mauritania through the Middle East to north-western India. Its natural habitat is dry savanna.
The lesser hedgehog tenrec is a species of mammal in the family Tenrecidae. It is the only species in the genus Echinops and is named in honour of Charles Telfair. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forests, shrubland, and shrubland and dry savanna.
The large-eared tenrec 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".
Cowan's shrew tenrec is a species of mammal in the family Tenrecidae.
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 greater long-tailed shrew tenrec is a species of mammal in the family Tenrecidae. It is endemic to Madagascar, where its natural habitats are subtropical or tropical moist forests.
The mole-like rice tenrec, also known as the fossorial tenrec or hova rice tenrec, is a species of mammal in the tenrec family. Like all other tenrecs, it is endemic to Madagascar. Its natural habitats are subtropical or tropical moist forests, swamps, freshwater lakes, and irrigated or seasonally flooded agricultural land.
The Ethiopian highland hare or Starck's hare is a medium-sized species of mammal in the rabbit and hare family, Leporidae. Its dorsal pelage is grizzled, buff white and spotted and streaked with black, while its belly fur is pure white and fluffy. It is endemic to the Ethiopian Highlands, ranging over the Afroalpine regions of the Shoa, Bale, and Arsi Provinces of Ethiopia. A herbivore, it mostly feeds on moorland grasses. The IUCN rates it as a species of least concern.
The Central Highlands, Central High Plateau, or Hauts-Plateaux are a mountainous biogeographical region in central Madagascar. They include the contiguous part of the island's interior above 800 m (2,600 ft) altitude. The Central Highlands are separated from the Northern Highlands of the northern tip of Madagascar by a low-lying valley, the Mandritsara Window, which has apparently acted as a barrier to dispersal for species in the highlands, leading to species pairs such as Voalavo gymnocaudus and Voalavo antsahabensis in the Northern and Central Highlands. Species restricted to the Central Highlands include the bats Miniopterus manavi and Miniopterus sororculus; the rodents Brachyuromys betsileoensis and Voalavo antsahabensis; the tenrecs Hemicentetes nigriceps and Oryzorictes tetradactylus; and the lemur Cheirogaleus sibreei. Because of the continuous habitat of the Central Highlands, there is little local endemism, unlike the Northern Highlands.
Hemicentetes is a genus of tenrec with two species, present on the island of Madagascar.
Tenrecinae is a tenrec subfamily endemic to the island of Madagascar. It contains the largest species in the family, Tenrec ecaudatus. All members of the genus possess spines, analogous to those of hedgehogs, for defense against predators.
Deimatic behaviour or startle display means any pattern of bluffing behaviour in an animal that lacks strong defences, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape. The term deimatic or dymantic originates from the Greek δειματόω (deimatóo), meaning "to frighten".
