North American Porcupine

E. DORSATUM

North American Porcupines are the second largest rodents in the United States, tipping the scales at 20 pounds.

Porcupines are covered in about 30,000 quills. They cannot throw or shoot their quills. Because quills are so lightly attached, they come off easily when a predator encounters them.

Despite spending most of their time on the ground, North American Porcupines are excellent climbers and surprisingly good swimmers.

Baby porcupines are born with soft quills that harden within 48 hours of birth.
