Rhizomys Sumatrensis
The large bamboo rat, Sumatran rat, or Indomalayan rat (''Rhizomys sumatrensis'') is a species of rodent in the family Spalacidae found in Southeast Asia. Range Bamboo rats are found in bamboo-rich environments of Cambodia, Southern China, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. It primarily resides in bamboo forests, montane forests, and agricultural areas. Description Individuals can reach lengths of to with a tail, and weigh from . All ''Rhizomys'' species share a common body form, with a massively broadened head, a plump body with short limbs, strong claws on both the pes and manus, small eyes and ears, and a short, sparsely haired tail that lacks scales (it is instead covered in soft, wrinkled skin). ''Rhizomys'' species have grey–brown to dull orange brown fur, rounded ears that just project through the fur, and granulated plantar pads on the manus and pes (compared to smooth pads in ''Cannomys badius'').

Chinese Bamboo Rat
The Chinese bamboo rat (''Rhizomys sinensis'') is a species of rodent in the family Spalacidae found in southern China, northern Myanmar, and northern Vietnam. Its habitat is bamboo thickets usually at high elevations, pine forests, and plantations. Description The head and body length is with a tail of and the weight is . The fur is soft with no guard hairs as are seen in the closely related hoary bamboo rat (''Rhizomys pruinosus''). On the side of the face and the crown the fur is dark greyish brown and on the body paler greyish brown. The under parts are scantily haired. Behaviour The Chinese bamboo rat is solitary, except during the breeding season. It breeds all year round, with a spring peak; litters of two to four young (eight maximum) are born naked, and are weaned at three months. Territory is marked by four to seven soil mounds marking plugged entrances (20 to 40 cm high and 50 to 80 cm across). Burrows are 20 to 30 cm deep and up to 45 m long. Escape t ...

Hoary Bamboo Rat
The hoary bamboo rat (''Rhizomys pruinosus'') is a species of rodent in the family Spalacidae found in Southeast Asia (Cambodia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), East Asia (China) and South Asia (India). Description The hoary bamboo rat is a robust rodent that reaches a head-and-body length of with a tail of . Its weight ranges from . The fur on the upper parts is greyish-brown or dark brown with a somewhat grizzled appearance due to the presence of white-tipped guard hairs. The under parts are paler greyish-brown and the tail is scantily haired. The skull is broad and somewhat flattened and the zygomatic arch is large. The upper incisors slope inwards and the broad molars are an orange colour. Distribution and habitat The hoary bamboo rat has a wide range which includes northern and north-eastern India, eastern Myanmar, Thailand, Laos, Cambodia, Vietnam, the Malay Peninsula, and southern China. It occurs from low ground to altitudes of above sea level. It occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spalacidae
The Spalacidae, or spalacids, are a family of rodents in the large and complex superfamily Muroidea. They are native to eastern Asia, the Horn of Africa, the Middle East, and southeastern Europe. It includes the blind mole-rats, bamboo rats, mole-rats, and zokors. This family represents the oldest split (excluding perhaps the Platacanthomyidae) in the muroid superfamily, and comprises animals adapted to a subterranean way of life. These rodents were thought to have evolved adaptations to living underground independently until recent phylogenetic studies demonstrated they form a monophyletic group. Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea. Characteristics Spalacids are mouse- to rat-sized rodents, adapted to burrowing and living underground. They have short limbs, wedge-shaped skulls, strong neck muscles, large incisor teeth, and small eyes and external ears. In the zokors, which dig primarily with their ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for 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/ricochetal (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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Burrowing Animals
An eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small amphipods, to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren. Vertebrate burrows A large variety of vertebrates construct or use burrows in many types of substrate; burrows can range wi ...
