  New World porcupine - Wikipedia, the free encyclopedia
The New World porcupines are large terrestrial rodents, distinguished by their spiny covering from which they take their name.
The porcupines are represented in the New World by the members of the family Erethizontidae, which have rooted molars, complete collar-bones, entire upper lips, tuberculated soles, no trace of a first front-toe, and four teats.
They are less strictly nocturnal than Old World species in their habits, and some types live entirely in trees while others have dens on the ground, their long and powerful prehensile tails help them balance when they are in the tree tops.

The family is typified by the common porcupine, Hystrix cristata, which is thick-bodied, grizzled, and fl in color; it grows to a length of 60 cm (24 in), with some of its quills exceeding 30 cm (12 in) in length.
The Erethizontidae, comprising the New World porcupines, include four forms: the tree porcupine of Central and South America, which has a prehensile tail; the Canada porcupine, Erethizon dorsatum; the thin-spined porcupine of Brazil; and the Amazonian porcupine.
The Canada porcupine is found in heavily wooded regions throughout North America, from Alaska to the northern extreme of Mexico.

If a predator encounters a porcupine, the porcupine forcefully slaps its tail against the head of the predator, firmly imbedding the spines in the face, lips, and mouth where they gradually penetrate and may eventually cause the predator's death by starvation.
While in trees the porcupine may feed on the inner bark to the extent that large areas of bark are removed; this may kill the tree, but seldom is of importance to the ecology of the community unless porcupine population density is very high.
Porcupine trails on snow are easily identified by the striae made by spines on the edge of the trail.

 Old World porcupine - Wikipedia, the free encyclopedia
The Old World porcupines are large representatives of the terrestrial rodent mammals, distinguished by their spiny covering from which they take their name.
The European Porcupine (Hystrix cristata) is the typical representative of a family of Old World rodents, the Hystricidae, all the members of which have the same protective covering.
Of the three genera, Hystrix is characterized by the inflated skull, in which the nasal chamber is often considerably larger than the brain-case, and the short tail, tipped with numerous slender-stalked open quills, which make a loud rattling noise whenever the animal moves.

 North American Porcupine (DesertUSA)
The Porcupine's feet have 4 toes on the forefeet and 5 on the hindfeet, all with long, curved claws and small textured knobby pads on the bottom.
Although the Porcupine is usually regarded as arboreal and found in woodlands, individuals wander widely and have been observed among Creosote in all of the North American deserts.
The Porcupine is primarily nocturnal and may rest by day in hollow trees and logs, crevices in rocky bluffs or underground burrows.

 MSN Encarta - Multimedia - Canadian Porcupine
Its strong claws and creased, furless foot pads grip branches well, and its spineless tail, prehensile in some New World species, is also useful in climbing.
In contrast, Old World porcupines are completely terrestrial.
North American porcupines subsist mostly on bark, needles, and (during the summer) grasses.
