At the present time, there are but a few handful of Tenrecs in the private hands of exotic animal breeders here in North America, mainly of the species Setifer setosus, the Greater Hedgehog Tenrec. Just to show how complicated the business of taxonomy can be, various species of tenrecs, via the process of convergent evolution, closely resemble shrews, mice, possums, and hedgehogs , while golden moles are, appropriately enough, reminiscent of true moles. Tenrecs are generally considered as relatives of the insectivores, such as moles, shrews and hedgehogs. [10] Continuing work on the molecular[11][12] and morphological[13][14][15][16] diversity of afrotherian mammals has provided ever increasing support for their common ancestry.

In addition to its webbed feet, keeled tail, and water-repellent fur, the amphibious tenrec also has the body form, habits, and diet of water shrews. Unusual for mammals, the permanent dentition in tenrecs tends not to completely erupt until well after adult body size has been reached. This creature lives on the Madagascar and on the nearby islands. Tenrecs were considered to represent the classic island pattern of many different species evolving from a common ancestor. Indicates an action that is generally true or habitual. Large enough to accommodate an adult tenrec (approx. Updates? At that time the island was probably a … At the same time, it is that critical factor that can most commonly leads people … 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!

The species of tenrecs that people keep as pets, eat many different types of insects. [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. Molecular Phylogenetics and Evolution 22:357–363. Some of these species, including the greater hedgehog tenrec, can be found in the Madagascar dry deciduous forests. One species, Microgale mergulus, is semiaquatic (similar to the lifestyle of their closest relatives, the otter shrews). The tenrecs of Madagascar belong to three subfamilies. Common tenrec, also known as tailless tenrec, is a type of mammal with unusual characteristics. Like lowland streaked Tenrecs, highland streaked tenrec habitats in the central upland region of Madagascar. The lesser and greater hedgehog tenrecs (Echinops telfairi and Setifer setosus, respectively) have densely spined upperparts and can curl into a protective ball. The single entrance is plugged with soil during the period of torpor. Other chunks of land later floated off to leave the island the size and shape we now know, situated 400 km off the Mozambique coast for the last 80 millions years. 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. For tenrecs, it's very important that they get a lot of insects in their diet. [9] At least some tenrec species are social, living in multigenerational family groups with over a dozen individuals. Large enough to accommodate an adult tenrec … The weight of the largest Tenrec is measured at 2.2 lb or 1 kg. The three species of rice tenrecs (genus Oryzorictes) are burrowers that will inhabit rice fields. (Note: one of each type is ideal, because tenrecs will use wire as a climbing "toy" and solid for running - but only one or the other is mandatory.) 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 hedgehoglike tenrecs have bulky bodies, have short or no external tails, and are terrestrial or arboreal.
