North American Porcupine

Location: We found this creature on may 3, 1805, near the mouth of the Porcupine River, Montana.
Discription: Large, chunky body, with short legs. Long guard hairs on front half of body; black or brown in the East, yellowish in the West. Quills on rump and tail. Length: 26–37 in (65–93 cm); tail: 5.9–11.8 in (14.8–30 cm). Weight: 7.8–40 lb (3.5–18 kg).

Interesting Note: Now i took a pretty big estimate on this but im pretty sure its right, the common porcupine has about 30,000 quills on its body, which it uses to defend itself against more agile predators.
