Common Punaré
The common punaré (''Thrichomys apereoides''), is a species of spiny rat endemic to Brazil. Description Like other members of the genus ''Thrichomys'', but unlike all other species of spiny rat, common punarés have no spines, and instead have a thick pelt of soft fur, which also extends for the full length of the tail. The fur is greyish-brown over most of the body, with whitish underparts and ears. There are also three pairs of small white spots on the face; one each above and below the eyes, and one at the base of the ears. They are the size of a large rat, measuring in length, not counting the tail. On average, they weigh , although males are slightly larger than females. Females have four teats, with one pair just behind the forelegs, and another in front of the hips. Distribution and habitat The common punaré is found only in eastern Brazil, where it inhabits a belt of relatively open caatinga and cerrado vegetation between the Amazonian and Atlantic Forests. It is f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highlands Punaré
The highlands punaré (''Thrichomys inermis'') is a caviomorph rodent of South America from the spiny rat family. It is endemic to gallery forest, savanna and rocky outcrop habitats in Bahia State within the Caatinga ecoregion of eastern Brazil at elevations from 260 m to 1030 m. It sometimes nests and often takes refuge in crevices in rock formations, as means of both predator avoidance and moderating temperature extremes. The species tolerates a degree of habitat disturbance. Although hunted, it is considered common throughout its range. Its karyotype has 2n = 26 and FN = 48. The etymology of the species name corresponds to the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... word '' inermis'' meaning ''unarmed, defenceless'' — itself constructed from the prefix '' i ...

Paraguayan Punaré
The Paraguayan punaré (''Thrichomys pachyurus'') is a caviomorph rodent of South America from the spiny rat family. With its skull averaging 55 mm long, it is the largest species in the genus ''Thrichomys''. It is found in savannas and forest edges in southwestern Brazil and northern Paraguay within the cerrado ecoregion. The species tolerates a degree of habitat disturbance, and is considered abundant throughout its range. Its karyotype has 2n = 34 and FN (fundamental number A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes.

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] |
