New World Porcupines
Erethizontidae
Tree-Climbing Quill Masters: New World Porcupines (Erethizontidae) are arboreal, slow-moving rodents native to North and South America. Unlike their Old World relatives, these porcupines are excellent climbers, spending much of their time in trees. Their most famous member, the North American Porcupine (Erethizon dorsatum), is the second-largest rodent in North America after the beaver, growing up to 90 cm (3 feet) long and weighing around 18 kg (40 lbs). What makes these porcupines truly unique is their coat of up to 30,000 sharp quills, which serve as an effective defense against predators. Each quill has tiny barbs that make removal difficult, and contrary to myth, porcupines cannot "shoot" them—but they detach easily upon contact. Some species, like the Brazilian Porcupine (Coendou prehensilis), even have prehensile tails, helping them grip branches as they navigate the treetops. New World porcupines are primarily herbivores, feeding on leaves, bark, fruits, and buds. Their strong, ever-growing incisors allow them to chew through tough plant material, making them well-adapted to forest life. These nocturnal creatures are generally solitary, though they may gather in small groups during the winter to share dens. Threats to these fascinating rodents include habitat destruction, hunting, and road accidents, particularly in areas where human expansion encroaches on their territory. Despite these challenges, many species remain widespread, continuing to thrive in forests from Canada to Argentina, using their armor of quills and sharp instincts to survive.
