Porcupine

Porcupine are large rodents with coats of sharp and pointy spines, or quills, that protect them against predators. Most porcupines are about 25–36 in. long, with a 8–10 in. long tail. Weighing 12–35 lb, they are rounded, large, and slow, and use aposematic strategy of defense. Porcupines occur in various shades of brown, grey and white. Porcupines' spiny protection resembles that of the unrelated erinaceomorph hedgehogs.

The North American porcupine is an herbivore; it eats leaves, herbs, twigs, and green plants such as clover. In the winter, it may eat bark. It often climbs trees to find food.
