Porcupines are rodents with a coat of sharp spines, or quills, that defend and camouflage them from predators. They are indigenous to the Americas, southern Asia, and Africa. Porcupines are the third largest of the rodents, behind the capybara and the beaver. Most porcupines are about 25–36 in (64–91 cm) long, with an 8–10 in (20–25 cm) long tail. Weighing 12–35 lb (5.4–16 kg), they are rounded, large and slow. Porcupines come in various shades of brown, gray, and the unusual white.
Prehensile-tailed Porcupine ~ are well adapted for life in the trees and rarely descend to the ground. They have compact bodies covered in short spines mixed with coarse hairs. They can be colorful, with shades of yellow, white and black. The quills can lay flat, or be erected if the porcupine is disturbed. Their head is small and their nose is round and bulbous and covered with short fine hair but no quills.
