Porcupines that become alarmed do not shoot their quills. They respond to the stimulus by raising them up similar to the way people respond to the weather by getting goose bumps.

Porcupines are strict vegetarians. In the spring they feed on leaves, twigs and green plants. In winter, they chew through the outer bark of fir, hemlock, aspen and pines trees to eat the tender layer of tissue below.

Porcupines live 5 to 6 years. They usually have one or two young, which are born with soft quills that harden within an hour. They open eyes about ten days later.

Porcupine quills are coated with a fatty acid that has a mildly antibiotic quality.

Porcupinefish can also inflate their bodies with water or air, but these fishes are also armed with well-developed spines from head to tail. These spines, which can be up to 5 cm (2 in.) long, make the porcupine fish even more difficult to attack.

Porcupines live in colonies, and all members of the groups will protect the young if threatened. These young are born in grasslined chambers within the burrow system. They are born fully furred with their eyes open.

Porcupines are solitary. They mate in fall or early winter. A single offspring is born after a seven month gestation. The well-developed young weigh about 3 pounds at birth, climb trees in two days and become sexually mature in their second year.

A porcupine produces one offspring at a time. Young are able to move about quite briskly shortly after birth and, unlike their stolid parents, are quite playful.

This porcupine sleeps during the day but is active at night. That’s when it searches the treetops for tasty leaves to eat. Sometimes it even snacks on lizards.

Crested porcupines are fairly social animals, often traveling in pairs or small family groups. Females maintain a separate den for rearing young, and generally forage alone. Adults may lick each other as well as the young.

Like all porcupines, the prehensile-tailed porcupine is not able to throw its quills (also called spines). Quills are barbed at the end and will become lodged in the person or animal who comes too close.

Old World porcupines do not climb or jump very well, but they are excellent swimmers.

In the wild, prehensile-tailed porcupines can be pretty tough. They have been known to bite and hit those who attack or try to capture them. They stomp their hind feet when excited and curl up in a ball if caught.

Crested Porcupine
Even though they may look scary with their pointy black and white quills covering their neck and back, Crested Porcupines only use them to defend themselves from predators.

Porcupine quills have microscopic barbs on the tip. They are usually around 75 mm long and 2 mm wide. Each animal has approximately 30,000 quills.

Porcupines possess a very unique defense system. A porcupine's first line of defense is escaping from danger by climbing up a tree. However, if such an escape is not possible, the porcupine has many options.

North American Porcupines are large, slow-moving, tree-climbing rodents, protected from predators by their formidable quills. In winter, they eat the bark, phloem, and cambium of trees, particularly conifers.
