picture info	Rodent 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 i ...

picture info	Echimyidae Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans. Characteristics In general form, most spiny rats resemble rats, although they are more closely related to guinea pigs and chinchillas. Most species have stiff, pointed hairs, or spines, that presumably serve for protection from predators. Many echimyids can break off their tails when attacked. This action may confuse predators long enough for the spiny rat to es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Echimys ''Echimys'' is a genus of the spiny rats family, the Echimyidae. Members of this genus are collectively called spiny tree-rats. The genus name ''Echimys'', and also its synonym ''Echinomys'', derive from the two Ancient Greek words (), meaning "hedgehog", and (), meaning "mouse, rat". Classification The genus contains three extant species * White-faced spiny tree-rat - ''Echimys chrysurus'' Dark spiny tree-rat - ''Echimys saturnus'' Vieira's spiny tree-rat - ''Echimys vieirai'' Members of the genera ''Callistomys'', '' Makalata'', ''Pattonomys'', and ''Phyllomys ''Phyllomys'' is a genus of arboreal spiny rat, geographically restricted to the forests of eastern Brazil. The etymology of the genus name derives from the two ancient greek words (), meaning "plant leaf", and (), meaning "mouse, rat". Phy ...'' were all formerly considered part of the genus ''Echimys''.

	Lonchothrix The tuft-tailed spiny tree rat (''Lonchothrix emiliae'') is a spiny rat species from Brazil south of the Amazon River, where it has been found in grassland and gallery forest. It is the only species in the genus ''Lonchothrix''. Very little is known about this rodent. It is small with an average adult weight of about 138 grams. It is nocturnal and solitary in habits. The genus and species were described by Oldfield Thomas in 1920. The genus name '' Lonchothrix'' derives from the two ancient greek words (), meaning "spear", and , (), meaning "hair". Phylogeny ''Lonchothrix'' is a member of the Echimyini clade of arboreal Echimyidae rodents. The closest relative of ''Lonchothrix'' is ''Mesomys'', reflecting the fact that these taxa have once been classified in the same subfamily (Eumysopinae Echimyidae is the family of neotropical spiny rats and their fossil relatives.

picture info	Mesomys ''Mesomys'' is a genus of South American spiny rats in the family Echimyidae. The genus name ''Mesomys'' derives from the two ancient greek words (), meaning "middle of, between", and (), meaning "mouse, rat". It refers to the fact that this rodent — literally the "middle mouse" — has been considered as an intermediate form related both to mice and jumping rats. Extant Species Phylogeny ''Mesomys'' is a member of the Echimyini clade of arboreal Echimyidae rodents. The closest relative of ''Mesomys'' is ''Lonchothrix'', reflecting the fact that these taxa have once been classified in the Eumysopinae Echimyidae is the family of neotropical spiny rats and their fossil relatives.

	Makalata ''Makalata'' is a genus of rodents in the family Echimyidae. Systematics The etymology of this genus name derives from a combination of letters inspired by the Suriname native name ''Maka-alata'' for spiny rats. This genus contains the following species: * Brazilian spiny tree-rat ('' Makalata didelphoides'') * Long-tailed armored tree-rat ('' Makalata macrura'') * Dusky spiny tree-rat ('' Makalata obscura'') * Peruvian tree-rat ('' Makalata rhipidura'') Phylogeny ''Makalata'' is the sister genus to ''Echimys'' and ''Phyllomys''. These taxa are closely related to the genera ''Pattonomys'' and ''Toromys'', reflecting the fact ''Pattonomys occasius'' and ''Toromys grandis The giant tree-rat (''Toromys grandis'') is a species in the family Echimyidae, the spiny rats. It is the only species in the monotypic genus ''Toromys''.
