The black-tailed hairy dwarf porcupine (''Coendou melanurus'') is a porcupine species from the family Erethizontidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname and Venezuela. This species was formerly sometimes assigned to ''Sphiggurus'', a genus no longer recognized since genetic studies showed it to be polyphyletic.

Johann Andreas Wagner
Johann Andreas Wagner (21 March 1797 – 17 December 1861) was a German palaeontologist, zoologist and archaeologist who wrote several important works on palaeontology. He was also a pioneer of biogeographical theory. Career Wagner was born in Nuremberg and received a PhD from the University of Erlangen in 1826 after spending some time in the University of Wurzburg (1814-16). He worked as a privatdozent at Erlangen after a tour that included a visit to Paris. In 1832 he became an adjunct to Gotthilf Heinrich von Schubert at the Munich zoological collection. In 1835 he was elected to the Bavarian Academy of Sciences and Humanities, Royal Bavarian Academy of Science. In 1845 he organized a survey of the distributions of 44 vertebrates (16 mammals, 27 birds, 1 reptile) across the districts of Bavaria under auspices of the Kingdom of Bavaria. In 1849 he was made third curator for the zoological collections. He was the author of ''Die Geographische Verbreitung der Säugethiere Da ...

Streaked Dwarf Porcupine
The streaked dwarf porcupine (''Coendou ichillus'') is a porcupine species in the family Erethizontidae. It is known from the lowlands (below an altitude of 400 m) of eastern Ecuador, and may be present in Peru as well. It appears to be nocturnal and arboreal in its habits. This species was formerly sometimes assigned to ''Sphiggurus'', a genus no longer recognized since genetic studies showed it to be polyphyletic. Its closest relatives are the frosted hairy dwarf porcupine (''Coendou pruinosus'') and the brown hairy dwarf porcupine The brown hairy dwarf porcupine (''Coendou vestitus'') is a species of rodent in the family Erethizontidae.

Mammals Of Venezuela
The fauna of Venezuela consists of a huge variety of animals. Venezuela's diverse wildlife includes manatees, Amazon river dolphins, and Orinoco crocodiles, which have been reported to reach up to in length. Some 23% of reptilian and 50% of amphibian species that inhabit the country are endemic to Venezuela. Overall, around 8,000 species (the world's 5th highest total) are endemic to the country. Venezuela hosts a total of 1,417 bird species, more than 351 mammals, 341 reptiles, 315 amphibians and more than 2,000 freshwater and marine fishes. Invertebrates groups have not been inventoried exhaustively, but among the well known groups there are around 900 species of marine molluscs, 1,600 butterflies, over 120 dung beetles species and 39 species of blowflies.Capelo, Juan C., Buitrago, Joaquín. 1998: Distribución geográfica de los moluscos marinos en el oriente de Venezuela.

Mammals Of Suriname
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Mammals Of Guyana
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the large ...

Rodents Of Brazil
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 ...

Brown Hairy Dwarf Porcupine
The brown hairy dwarf porcupine (''Coendou vestitus'') is a species of rodent in the family Erethizontidae. Found in the Andes in Colombia and Venezuela, its natural habitat is subtropical or tropical moist lowland forests. It is not easy to study as it is known only from a few specimens and was not recorded from 1925 until the 2000s. The porcupine is nocturnal and arboreal, feeding on leaves, shoots, and fruits. Habitat loss severely threatens it, and it may even be extinct. Formerly listed as vulnerable, it is now designated data deficient. It is not known from any protected areas or conservation measures. This species was formerly sometimes assigned to ''Sphiggurus'', a genus no longer recognized since genetic studies showed it to be polyphyletic. Its closest relative is the frosted hairy dwarf porcupine The frosted hairy dwarf porcupine (''Coendou pruinosus'') is a porcupine species in the family Erethizontidae from Colombia and northern and eastern Venezuela.
