Each quill is connected to a muscle at its base, allowing the porcupine to raise its quills when it feels threatened. [4] The longest quills are located on the neck and shoulder, where the quills form a "skirt" around the animal. [4] These quills can grow up to 51 cm (20 in) long, [4] with most measuring between 15 and 30 cm (5.9 and 11.8 in). [5]
Porcupines can use their quills to fend off predators. They are nocturnal creatures that are found in forests, grasslands, desert shrub and tundra in the U.S., Canada and Mexico.
The two subfamilies of New World porcupines are mostly smaller (although the North American porcupine reaches about 85 cm or 33 in in length and 18 kg or 40 lb), have their quills attached singly rather than grouped in clusters, and are excellent climbers, spending much of their time in trees. The New World porcupines evolved their spines ...

The most distinguishing feature of the porcupine is its coat of quills. An adult porcupine has about 30,000 quills that cover all of its body except its underbelly, face, and feet. Quills are modified hairs formed into sharp, barbed, hollow spines. They are used primarily for defense, but also serve to insulate their bodies during winter.
Porcupines are known for their long quills. Their name derives from French words for pig and spike, although they are not pigs, but rodents related to large South American animals like capybaras.
