Leptomys
''Leptomys'' is a genus of rodent endemic to New Guinea. It is considered part of the New Guinea Old Endemics, meaning it was part of the first wave of murine rodents to colonize the island. Leptomys are seen to have minimal adaptations to their aquatic life style. Elongated hind feet accompanied by elongated centre toes suggest the ability to leap. The third molar which is lost is many rodents is retained but smaller in size. Small eyes and ears can be seen amongst its velvety soft fur.

Long-footed Water Rat
The long-footed water rat (''Leptomys elegans'') is a species of rodent in the family Muridae. It is found in the mountains of southern Papua New Guinea. Its natural habitat is subtropical or tropical dry forest. Distribution and habitat The long-footed water rat is endemic to the eastern half of the island of New Guinea. Its range includes the Owen Stanley Range, Mount Dayman, Mount Sisa, and Mount Victory in Papua New Guinea, and its altitudinal range extends from . Relatively few specimens of this rat have been observed, and its habitat includes secondary forest and old gardens, and it is presumed to be also present in primary forest. Status No particular threats are known for this species. It is sometimes hunted, presumably for food, but this is unlikely to be of much significance to the species. Previously classified as " critically endangered", the long-footed water rat has been found to have a much wider distribution and to be more plentiful than was once thought and ...

Leptomys Paulus
''Leptomys paulus'' is a small rodent belonging to the family Muridae endemic to New Guinea. Description ''L. paulus'' has a head and body length of between 117 and 132 mm, and a tail length of between 138 and 163 mm. Its ears are 18 to 23 mm, dark brown in colour and have a few dark hairs, its feet are 31 to 36 mm . It can weigh up to 52 g.

The tail is almost hairless with a white tip. Habitat The species has been observed in the tropical low-montane Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the eco ...

Murine Rodent
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in mur ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rodent Genera
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...
