The North American porcupine is one of the largest rodents found in North America, coming second to the beaver. The porcupine is the prickliest of the rodents, though its Latin name means "quill pig". There are more than two dozen porcupine species, and all boast a coat of needle-like quills to give predators a sharp reminder that this animal is no easy meal. A porcupine uses its large two front teeth for gnawing off bites of food. The incisors continue to grow throughout the porcupine's life, and the constant gnawing keeps them worn down to the perfect size.
Porcupines are covered in about 30,000 quills. They cannot throw or shoot their quills but come off easily when a predator encounters them since they are lightly attached!
Porcupines produce an antibiotic skin secretion, which reduces the risk of infection due to self-quilling as they are notoriously clumsy creatures!
