The average porcupine has approximately 30,000 quills. These quills are specially designed hairs and are very sharp and have a barbed tip. They are used as a defense mechanism and only used when the porcupine feels threatened. 3,ooo

I think it serves as they're protection against predators.
It has six thousand .
when porcupines are born they automatically have their quills but the quills don't harden until a few days after, then they can use them as a defense mechanism
A porcupine has quills to defend themselves against harm's way (defend them from predators).
over 30,000 quills
Typical porcupine - 30,000 quills Typical hedgehog - 6,000 quills
The quills of a porcupine are modified hairs; they would not be described as fur, but they derive from fur in an evolutionary sense.
It is very unlikely they could live without their quills in the wild. The quills are the porcupines defense mechanism; without them, they are very vulnerable to attack.
You can't eat porcupine quills anyway because they are made from material that's hard and can break your teeth. I wouldn't advise eating them anyway.
