Which small mammal is known for its sharp quills and is found in northern Arkansas woodlands?

The North American Porcupine is known for its distinctive sharp quills, which serve as a defense mechanism against predators. These quills are modified hairs coated with keratin, making them sharp and difficult to remove once they latch onto a threat. In northern Arkansas woodlands, the North American Porcupine is a common resident, and its ability to climb trees allows it to access a variety of food sources, including bark, leaves, and fruits.

While the other small mammals mentioned have their own unique characteristics, they do not possess the signature sharp quills that make the porcupine so easily identifiable. The Eastern Chipmunk is a small rodent known for its stripes and burrowing habits, the American Badger is a burrowing carnivore with a stocky body, and the Southern Raccoon is easily recognized by its mask-like facial markings and dexterous front paws, none of which have the defensive features of quills.
