Overview

Could a porcupine make a good pet? Do they ever stick themselves or other porcupines with their quills? In this latest addition to the Animal Answer Guide series, we learn about these mysterious animals' "pincushion defense," along with the following facts:

• Porcupines survive on a diet of leaves, bark, and fruit
• Quills are actually modified hairs
• There are 26 species of porcupines (and counting)
• Old World and New World porcupines have a common ancestor but evolved independently
• New World males will gather to fight ferociously over a single female

Porcupines: The Animal Answer Guide presents solid, current science in the field of porcupine biology. Uldis Roze compares and contrasts porcupines in terms of body plan, behavior, ecology, reproduction, and evolutionary relationships. He examines the diversity of porcupines from around the world—from North and South America to Africa and Asia.

This guide explores the interactions between humans and porcupines, including hunting, use of quills by aboriginal societies, efforts to poison porcupines, and human and pet injuries (and deaths) caused by porcupines. Roze also highlights the conservation issues that surround some porcupine species, such as the thin-spine porcupine of Brazil, which is so rare that it was thought to be extinct until its rediscovery in the 1980s.

Read an Excerpt

In this book I have often felt like a speaker responding to questions from an erudite audience. Good questions can lead to insights that neither party anticipated—one definition of the scientific process. The questions can seem simple: What is a porcupine? What do porcupines eat? How do they survive the winter? Or the questions may have layers of complexity: What are the porcupines’ closest relatives? How do scientists tell porcupine species apart? How will global warming affect the porcupines? But one of the most important questions in this series is the last one: What don’t we know about porcupines?

The amount we don’t know about porcupines is staggering. This is partly because of the nocturnal, tropical-forest lifestyle of most porcupines of the world, but also because of the paucity of molecular biology studies of these animals and because their lifestyles have few parallels with other animal groups. These mysteries make porcupines a lure to scientists and nature lovers alike.
