How many quills does a North American Porcupine have?
A. 750 B. 5,000 C. 30,000 D. 1,500,000
ANSWER: (c) 30,000 Having so many quills means the porcupine is not incapacitated by a single encounter with an enemy, since only several hundred quills may be dislodged. As quills are lost they are replaced by new ones – these are white and sharp, and remain firmly anchored in the skin until they are fully grown.
