[19][20] While the fossil record of tenrecs is scarce, at least some specimens from the early Miocene of Kenya show close affinities to living species from Madagascar,[21] such as Geogale aurita. The eight tenrec genera belong to the family Tenrecidae, which also includes African otter shrews (subfamily Potamogalinae). : The Madagascar tenrec is found throughout the island in all habitat types, with the exception of wetlands and marshes.

Tenrecs have a very quick gestation cycle - between 50-65 days, and like some rodents, their young are very underdeveloped and require a great deal of care in their early days. The three subfamilies, 8 genera, and 31 extant species of tenrecs are:[23], CS1 maint: multiple names: authors list (, "Late Eocene Potamogalidae and Tenrecidae (Mammalia) from the Sperrgebiet, Namibia", "Multiple Loci and Complete Taxonomic Sampling Resolve the Phylogeny and Biogeographic History of Tenrecs (Mammalia: Tenrecidae) and Reveal Higher Speciation Rates in Madagascar's Humid Forests", "Molecular phylogeny and divergence times of Malagasy tenrecs: Influence of data partitioning and taxon sampling on dating analyses", "Molecular evidence for multiple origins of Insectivora and for a new order of endemic African insectivore mammals", "Cross-species chromosome painting in the golden mole and elephant-shrew: support for the mammalian clades Afrotheria and Afroinsectiphillia but not Afroinsectivora", "Early tertiary mammals from North Africa reinforce the molecular Afrotheria clade", "A new estimate of afrotherian phylogeny based on simultaneous analysis of genomic, morphological, and fossil evidence", "The Evolutionary Origin of Descending Testicles", "Molecular phylogeny and divergence times of Malagasy tenrecs: influence of data partitioning and taxon sampling on dating analyses", "Tenrec phylogeny and the noninvasive extraction of nuclear DNA", Bizarre mammals filmed calling using their quills. 1. Anatomical and molecular studies, for example, suggest that they may be more closely related to golden moles (order Chrysochloridea). For example, when a baby tenrec … We use different types of bedding in different parts … streaked tenrec. Geogale, Echinops) are adapted to the arid spiny desert in the south-west of Madagascar.The aquatic tenrec (Limnogale mergulus) requires clear, running freshwater.Some species - such as tailless tenrecs (Tenrec ecaudatus) and streaked tenrecs (Hemicentetes) - appear able to … To make it confusing though the tenrecs that are kept as pets have been named the lesser or greater hedgehog tenrecs, using the word hedgehog to describe their spiny hairs. Tenrecs prefer areas near the water. Some species of tenrec live in the water, and they can eat small fish and frogs.

As tectonic plates shifted subtly on the Earth's surface, the land mass moved out slowly into the Indian Ocean. Omissions?

Common tenrec can be found in subtropical and tropical forests, savannas, scrublands, pastures and urban areas. This tense is used to … Its appearance might resemble one of a hedgehog because of the body structure as well as the quills found on its back. The common ancestry of these animals, along with aardvarks, hyraxes, elephants, and sea cows in the group Afrotheria, was not recognized until the late 1990s. This technique is more common for insects and snakes. There are 20 recognized types of tenrec… [18] All of the species, semiaquatic or not, appear to have evolved from a single, common ancestor, with the otter shrews comprising the next, most-closely related mammalian species. 1) Simple Present Tense -.

There are 30 different kinds within the afrotherian family Tenrecidae. Tenrecs have been in captivity for about the same length of time as hedgehogs, but due to their slow reproductive capabilities, they are not nearly so numerous or popular. Tenrecs look like hedgehogs but are classified in their own family. It feeds primarily upon earthworms The smallest species are the size of shrews, with a body length of around 4.5 cm (1.8 in), and weighing just 5 g (0.18 oz), while the largest, the common or tailless tenrec, is 25 to 39 cm (9.8 to 15.4 in) in length, and can weigh over 1 kilogram (2.2 lb). The Tenrecidae have undergone adaptive radiation to produce forms resembling shrews, moles, and hedgehogs, and Potamogale (otter shrew) is an aquatic form closely resembling true otters. Strange Animals. In addition to the two species of hedgehog tenrec Setifer setosus and Echinops telfairi, are the two species of streaked tenrec Hemicentetes semispinosus and H. nigriceps.

One species, Microgale mergulus, is semiaquatic (similar to the lifestyle of their closest relatives, the otter shrews). The tenrec, like much of Madagascar’s unique wildlife, is coming under more and more pressure for survival as their forest habitat disappears to make way for fields of rice and other crops. Subfamily Oryzorictinae includes the 21 species of Oryzorictes, Limnogale, and Microgale; subfamily Tenrecinae includes four single-species genera, Echinops, Setifer, Tenrec, and Hemicentetes; Geogale aurita is the sole member of subfamily Geogalinae.

The stridulation sounds produced by tenrecs appear to be used solely for intra-species communication and not for warning predators, but the bright yellow and black stripes of spines in streaked tenrecs and juvenile common tenrecs may be aposematic -- a message to enemies to stay away! Jun 8, 2013 - The Tenrecidae (common name tenrecs) are a family of 34 species of mammals found on Madagascar and in parts of the African mainland. solenodons, and tenrecs—that subsist primarily on insects, other arthropods, and earthworms.…. Its habitats include subtropical or tropical dry forests, dry forests, dry savannah, subtropical or tropical dry shrub land, and subtropical or tropical dry lowland grassland. Tenrecs are generally considered as relatives of the insectivores, such as moles, shrews and hedgehogs. [2] Tenrecs are widely diverse; as a result of convergent evolution[3] some resemble hedgehogs, shrews, opossums, rats and/or mice. The shrewlike tenrecs, such as the long-eared tenrec (Geogale aurita), have soft, dense fur and are analogous to true shrews (family Soricidae) found on other continents. Some commercial foods are available – labeled insectivore diet – but they will also take a few snacks. They are native to Madagascar and parts of the African mainland. Their other senses are well developed, however, and they have especially sensitive whiskers. In the island nation of Mauritius, and also on the Comoran island of Mayotte, some of the inhabitants eat tenrec meat, though it is difficult to obtain (as it is not sold in shops or markets) and difficult to prepare correctly.
