North American porcupines live in most all of North and South America, including Alaska. They live in forests in tunnels they have dug in the ground. Living mostly on leaves and the bark of trees, they will climb up the tree and eat the bark, possibly killing the tree. They are about 3ft long and weigh about 20lbs. When born after the 210 day gestation, they are already covered in quills. They are brownish black and are covered in 2 inch quills. The quills protect them from most predators because when they feel threatened they spray the quills inbedding them in their attacker. The quills contain barbs which when tore out may cause infections. The only animals that really hunt porcupines is fishers which kill the porcupines by flipping them onto their backs. There is no set season to hunt porcupines and no bag limit.
