Porcupines are large rodents; whose coats have spiny quills that come in handy to protect them against predators. Porcupines are strictly herbivores, preferring a diet of fruits, foliage, leaves, and twigs.

Most porcupines’ diet changes depending on the season. Bio Explorer explores the insight into the different porcupine species diets, how porcupines hunt if they do, when they eat, how often they eat, what eats porcupines, and their role in the animal food chain.

Porcupines Diet by Types

Two main categories of porcupines exist; the Old-World porcupines classified under the family Hystricidae and the New-World porcupines classified under the family Erethizontidae.

  • The Old-World porcupines inhabit most of Africa, Asia, and southern Europe.

  • These two types of porcupines are very different from each other. For example, the old-world porcupines are heavily built with rounded heads. They also have flattened or cylindrical spines lining their bodies.
  • On the other hand, new-world monkeys are large rodents with rounded heads and blunt noses whose spines that cover their bodies are mixed with long soft hairs.

The following sections will explore the different porcupine species classified under the two distinct categories.
