Prehensile-tailed Porcupine
The prehensile-tailed porcupines or coendous (genus ''Coendou'') are found in Central and South America. Two other formerly recognized Neotropical tree porcupine genera, ''Echinoprocta'' and ''Sphiggurus'', have been subsumed into ''Coendou'', since ''Sphiggurus'' was shown by genetic studies to be polyphyletic, while ''Echinoprocta'' nested within ''Coendou''. Characteristics Among the most notable features of ''Coendou'' porcupines are their unspined prehensile tails. The front and hind feet are also modified for grasping. These limbs all contribute to making this animal an adept climber, an adaptation to living most of their lives in trees. They feed on leaves, shoots, fruits, bark, roots, and buds. They can be pests of plantation crops. They also make a distinctive "baby-like" sound to communicate in the wild. Their young are born with soft hair that hardens to quills with age. Adults are slow-moving and will roll into a ball when threatened and on the ground. The record ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilian Porcupine
The Brazilian porcupine (''Coendou prehensilis'') is a porcupine found in Brazil, Argentina, Uruguay, Colombia, Venezuela, Guyana, French Guiana, Peru, Paraguay, Suriname, Bolivia and Trinidad, with a single record from Ecuador. It inhabits tropical forests at elevations up to 1500 m. Description The body is covered with short, thick spines that are whitish or yellowish in color, mixed with the darker hair, while the underside is grayish. The lips and nose are fleshy. The tail is prehensile, with the tip curling upward so as to get a better grip on tree branches. This porcupine can grow to forty inches long (1 m), but half of that is tail. It weighs about . No spines are found on the tail, which is long (). Its feet are reflective of their arboreal lifestyle, well-adapted for gripping branches, with four long-clawed toes on each. Behavior This shy, nocturnal Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Santa Marta Porcupine
The Santa Marta porcupine (''Coendou sanctamartae'') is a rodent in the family Erethizontidae. It is known from dry forests on the lower slopes of the Sierra Nevada de Santa Marta and Serranía del Perijá mountains of northern Colombia, at altitudes below 500 and 1100 m, respectively, and intervening lowlands, and may also be present in nearby parts of Venezuela. It has been described as a subspecies of '' C. prehensilis'', although the latter may be a species complex. Its karyotype A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes.

Roosmalen's Dwarf Porcupine
Roosmalen's dwarf porcupine (''Coendou roosmalenorum'') is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality. It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens. It was soon assigned to the genus ''Sphiggurus'', although this genus was not recognized by the authors. Genetic studies in 2013 have since showed ''Sphiggurus'' to be polyphyletic (this taxon was omitted from the study). Nonetheless it is commonly classified as ''Sphiggurus roosmalenorum''. ''Coendou roosmalenorum'' may be misspelled due to a conflicting basionym In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses.

Andean Porcupine
The Andean porcupine (''Coendou quichua'') or Quichua porcupine is a species of rodent in the family Erethizontidae. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture. Taxonomy Although it is morphologically distinctive, it has sometimes been described as a subspecies of the bicolored-spined porcupine (''C. bicolor''). However, genetic studies have shown it to be closest to the stump-tailed porcupine (''C. rufescens''). Rothschild's porcupine (''C. rothschildi'') of Panama was formerly considered a distinct species, but phylogenetic evidence indicates that both are synonymous. Description The Andean porcupine is a medium-sized porcupine with a head-and-body length of between and a tail length of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amazonian Long-tailed Porcupine
The Amazonian long-tailed porcupine (''Coendou longicaudatus''), also known as Cerrado's long-tailed porcupine, is a species of rodent in the family Erethizontidae, the New World porcupines. Found across most of South America, it was first described by François Marie Daudin in 1802. It was for some time considered a subspecies of the Brazilian porcupine (''Coendou prehensilis''). ''C. prehensilis'' was split into three distinct species in 2021: * the Brazilian porcupine, ''C. prehensilis''; * the Amazonian long-tailed porcupine, ''C. longicaudatus''; and * the Baturite porcupine, ''C. baturitensis''. The species has been recorded as exhibiting albinism and is susceptible to several fungal infections Fungal infection, also known as mycosis, is Infection, a disease caused by pathogenic fungi, fungi.
