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.

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.

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.

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.

There are three families of pufferfish, Tridontidae (a single three-toothed species), Tetradontidae (smooth and sharpnose puffers with four teeth), and Diodontidae (the spiny pufferfish, burrfishes, and porcupinefishes with two fused teeth).

These quills are sharp (though unlike a porcupine's quills, they are not barbed) and are controlled by a series of muscles, so when a hedgehog feels threatened the quills are raised.

They've been reported to eat such things as birds, rats, monkeys, deer and even porcupines! The prey is swallowed whole and digested while the python basks in the sun, which keeps its body temperature high enough to be able to digest properly.
