Short-sighted critter wields 30,000 sharp objects, wants habitat protected


They have poor eyesight and would barely win a race against a turtle, but porcupines are not defenseless against predators. Their coats include about 30,000 pointy quills; modified hairs which with a flick of the tail, can be dislodged into an enemy’s flesh. During a single encounter, a porcupine may lose hundreds of quills – which can measure up to 12 centimeters long – but can regrow them just like other hairs.
