Introduction of rats to the island increased competition for food and resulted in minor decrease in the number of tenrec in the wild. Whilst rampant deforestation means one in five tenrecs is threatened with extinction, most conservation attention in the country is focused on larger, more charismatic species, such as lemurs. People may wonder why understanding tenrecs and trying to protect them is important when most people have never even heard of these weird animals. In 2003, Madagascar's President Marc Ravalomanana committed to triple the island’s protected area coverage, adding a further 5 million hectares, and placing more than two-thirds of the country's remaining forest under formal protection.

The body covered with black and white striped quills. Habitat loss is the greatest threat to most species. Lesser tenrecs are smaller than greater Madagascar tenrecs. There are more than one species of tenrec that live on Madagascar, but lowland streaked tenrecs are only found on the East side of the island which is covered mostly by a tropical rainforest. When threatened, these tenrecs curl into a ball, leaving only sharp spines—modified hairs—exposed. These tenrecs range in size from the small dark M. parvula (3 g) to M. talazaci (up to 37 g). Experiences Tours. Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, featured multi-media fact-files for more than 16,000 endangered species. Why do Dogs Dig Holes? Population threats. Tenrecs are primitive insectivores (distantly releated to shrews and hedgehogs) that occur only on the island of Madagascar, where they underwent an evolutionary radiation. Tenrecs with very narrow distributions or specific threats may need extra help. "Earth's Endangered Creatures - Aquatic Tenrec Facts" (Online) - Licensed article … Tenrec diet is based on invertebrates. To Cite This Page: Glenn, C. R. 2006. They are also considered primitive physiologically, since all species have relatively low body temperatures and metabolic rates relative to their body size, and several specied enter torpor regularly. Large-eared Tenrec. Other tenrecs such as Setifer setosus and Tenrec ecaudatus have been proposed to be raised as ‘mini-livestock’ for human consumption, so it is possible that both highland (H. semispinosus) and lowland streaked tenrecs (H. nigriceps) could be looked upon as an exotic game meat. There are two species in the genus Hemicentetes, H. semispinosus and H. nigriceps; both are found only on Madagascar.Lowland streaked tenrecs (H. semispinosus) are found in the rainforests on the east side of the island and highland streaked tenrecs (H. nigriceps) are found in humid forest and plateau savanna boundary habitat in the central upland portion of Madagascar. Females may have more than one litter per year, usually with five to eight babies at a time. 5 to 8 inches long. A meeting held in Madagascar in 2001 and attended by numerous specialists proposed new conservation status designations for Malagasy vertebr… Also read difference between ape and monkey. Due to the speed of maturation and relatively large litter size, a family group may comprise more than 20 individuals from three generations. Although small mammals are often neglected in large conservation programmes, aquatic tenrecs would make ideal flagship species for integrated forest and freshwater conservation programmes in eastern Madagascar. See more ideas about Hedgehog, Cute pictures, Weird animals. Behavior and reproduction: Unlike most other tenrecs, which are loners much of the year, yellow-streaked tenrecs can either live alone or share their burrows with up to two dozen members of their families, including parents, grandparents, cousins, and siblings. The Aquatic Tenrec (Limnogale mergulus) is a species of concern belonging in the species group "mammals" and found in the following area(s): Madagascar. This quiz measures your understanding of tenrecs and can be taken on a computer or mobile device. Endangered species are considered more threatened than vulnerable species. The ovulation period lasts for 55 to 63 days, with an average of delivering 2 to 11 young Tenrecs. The aquatic tenrec feeds on a range of prey in its freshwater habitat, but favours aquatic insect larvae and crayfish. And considering its size, it gets difficult to trace them. It is a small species (about 7g) adapted for life in the arid south-west and specialised in a termite diet. A patch of spines on the back form what is known as a stridulating organ - the spines can rub together and produce a type of ultrasound that keeps the family groups together. The species nests in the fixed burrows located near the water bodies. This is a complete list of endangered mammalian species and subspecies evaluated by the IUCN. They’re only found at 10 sites in Madagascar, and since the biggest of these ratlike creatures are only 17 centimeters (6.7 in) long, they’re hard to spot. Streaked tenrecs (Hemicentetes) are so unique nothing like them ever evolved elsewhere. Tenrecs and hedgehogs are not endangered and are of least concern. The giant otter shrew, Potamogale velox, is widespread in the streams and rivers of central African forests, but the other two species have restricted distributions. They forage together, maintaining contact by using their stridulating organs. The binomial name of these species is Hemicentetes Nigriceps. Particularly important is the mobilization of funding resources and, to support this, the government of Madagascar, WWF and CI are creating the Madagascar Foundation for Protected Areas and Biodiversity. According to IUCN the species is classified as least concern. In spite of their many adaptations, tenrecs still exhibit a number of characteristics which make them distinct from other small mammals and which were probably typical of the earliest mammals. 6 Aquatic Tenrecs.

While, when it’s getting too cold, they usually undergo hibernation. The larger species adapted for foraging on the ground and eating diverse prey evolved defensive spines and look, at least externally, just like hedgehogs. Tenrecs also use their quills to communicate. This reproductive strategy also allows the female to save energy. Insects and their larvae are the most commonly consumed prey items. Tenrecs are widely diverse; as a result of convergent evolution, they resemble hedgehogs, shrews, opossums, mice and even otters. Tenrecs are widely diverse; as a result of convergent evolution some resemble hedgehogs, shrews, opossums, rats and/or mice.They occupy aquatic, arboreal, terrestrial and fossorial environments. This aims to raise US$50 million in the next five years and has already made a good start. These species are unusual insectivorous that forms a distinct feature. They eventually control the population of these invertebrates. Also known as Web-footed Tenrec, this species is the only known semiaquatic tenrec. Experiences & Tours. However, prior to our study, no one had tested whether this apparently high diversity was more than skin deep. Lowland streaked tenrec play an essential role in the environment by feeding upon worms. Its back is covered in sharp, cream- and dark-colored spines, which serve as an effective defense when the animal rolls into a ball.

Such traits include nocturnal activity patterns, small body size, the retention of a cloaca as a common uro-genital opening, abdominal testes, poor eyesight and a dependence on their sense of smell and hearing. Geographic Range. Greater Madagascar tenrecs are spiky, nocturnal, insect-eating small mammals. Eulipotyphla, Erinaceidae, Atelerix albiventris.

For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". Main threats and pressures: Habitat loss for agriculture, infrastructure, mining and urbanization (all species) Encroachment of habitat by cattle or introduced species such as wild boar (all species) Hunting for bushmeat (larger tenrecine species) Incidental capture in fish traps (aquatic tenrec, otter shrews) Limited pet trade (some larger species) Climate change … By the appearance and lifestyle it reminds of hedgehogs, but in fact tenrecs inhabit entirely different geographic regions. Sleeping period is circumstantial to the weather, temperature and accessibility of food. The tenrecs will receive food from the keepers until they are a month old and can begin eating solid foods on their own.
