North American Porcupine
The porcupine is one of the most uniquely recognizable creatures in the world. They have more than 30,000 quills covering their bodies. The quills lay flat unless the animal is threatened. They are capable swimmers and good tree climbers and they use their quills as a last resort in defending themselves.
Porcupines are nocturnal and do not hibernate. They eat green plants, leaves, clover and in the winter will eat bark. Porcupines live in wooded areas. They are solitary animals, but may den up with other porcupines in the winter.
Porcupines have only one baby at a time. The baby is born with it's eyes open and is covered with soft quills. The quills harden after a few hours. They are full grown at six months of age.
