The porcupine is the prickliest of
rodents, though its Latin name means “quill pig.” There are about two
dozen porcupine species, and all boast a coat of needle-like quills to
give predators a sharp reminder that this animal is no easy meal.
Some quills, like those of Africa’s crested porcupine, are nearly a foot (30 centimeters) long.
Porcupines have soft hair, but on their
back, sides, and tail it is usually mixed with sharp quills. These
quills typically lie flat until a porcupine is threatened, then leap to
attention as a persuasive deterrent.
Porcupines cannot shoot them at predators as once thought, but the quills do detach easily when touched.
Many animals come away from a porcupine
encounter with quills protruding from their own snouts or bodies. Quills
have sharp tips and overlapping scales or barbs that make them
difficult to remove once they are stuck in another animal’s skin.
Porcupines grow new quills to replace the ones they lose.
The porcupines found in North and South
America are good climbers and spend much of their time in trees. Some
even have prehensile (gripping) tails to aid in climbing.
The North American porcupine is the only
species that lives in the U.S. and Canada, and is the largest of all
porcupines. A single animal may have 30,000 or more quills.
North American porcupines use their large
front teeth to satisfy a healthy appetite for wood. They eat natural
bark and stems, and have been known to invade campgrounds and chew on
canoe paddles.
North American porcupines also eat fruit, leaves, and springtime buds.
Other porcupine species live in Africa,
Europe, and Asia. These animals usually live on the ground and can
inhabit deserts, grasslands, and forests.
Female porcupines have between one and
four young, depending on the species. Babies have soft quills at birth,
which harden within a few days. Most young porcupines are ready to live
on their own at about two months of age.
