Parasite Rex: Inside the Bizarre World of Nature's Most Dangerous Creatures Paperback – Illustrated, November 9, 2001
Purchase options and add-ons
For centuries, parasites have lived in nightmares, horror stories, and the darkest shadows of science. In Parasite Rex, Carl Zimmer takes readers on a fantastic voyage into the secret universe of these extraordinary life-forms—which are not only among the most highly evolved on Earth, but make up the majority of life’s diversity. Traveling from the steamy jungles of Costa Rica to the parasite-riddled war zone of southern Sudan, Zimmer introduces an array of amazing creatures that invade their hosts, prey on them from within, and control their behavior. He also vividly describes parasites that can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead. This comprehensive, gracefully written book brings parasites out into the open and uncovers what they can teach us all about the most fundamental survival tactics in the universe—the laws of Parasite Rex.

Editorial Reviews
Review
Kevin Padian The New York Times With Parasite Rex, Zimmer proves himself as fine a science essayist as we have.
Mark Ridley The New Scientist A nonstop delight...Zimmer is a colorful writer, and takes full advantage of the macabre natural history of parasites.
Susan Adams Forbes Zimmer is such an accomplished, vivid writer that he is able to weave these revolting beasts into an engrossing story that you will read to the last page.

About the author

Carl Zimmer is the author of fourteen books about science. His latest book is Life’s Edge: The Search for What It Means to Be Alive.
Zimmer’s column Matter appears each week in the New York Times. His writing has earned a number of awards, including the Stephen Jay Gould Prize, awarded by the Society for the Study of Evolution. His previous book, She Has Her Mother’s Laugh, won the 2019 National Academies Communication Award. The Guardian named it the best science book of 2018.
Zimmer is a familiar voice on radio programs such as Radiolab and is professor adjunct at Yale University. He is, to his knowledge, the only writer after whom both a species of tapeworm and an asteroid have been named.

In this book, Zimmer introduces us to the amazing array of parasites that exist on this planet. He discusses the history of parasitology, and convinces the reader that these creatures' importance has long been overlooked. In fact, he makes a convincing case that parasites may be responsible for a lot of complex animal behaviors, including perhaps sexual reproduction. So I guess next time you're feeling romantic, you have parasites to thank!
This book explores the many clever ways that parasites have evolved to exist within environments that are usually very specialized and often very hostile. Some use mind control. Some undertake amazingly complex journeys.
Zimmer imparts a lot of information in this book, and it is often fairly scientifically sophisticated. However, this book is still readily accessible (and fascinating) for those without a background in biology. This book has changed how I view the natural world, and I have recommended it to several friends.
"Parasite Rex" is an interesting look at the evolution and biology of parasites--but only for the strong of stomach.
In a sense it was comforting to read that we are not the most savage, efficient predators on Earth. Witness the parasite Sacculina that turns crabs into zombies--the slug-like female enters the crab through a convenient leg joint and gradually fills its whole body cavity, even wrapping roots around its host's eyestalks. The crab continues its shadow-crab life, sidling through the surf, eating mussels and clams. However, it stops moulting and growing as these activities would funnel energy away from Sacculina. If the parasite becomes pregnant, it doesn't matter whether the crab started out as male or female--it will brood and hatch the next generation of Sacculina as if the tiny larvae were its own children.
Sacculina's life-style is rather hard on the crab, but it is only one of the amazingly efficient (and bizarre) parasites described in this book. Other parasites have adopted Sacculina's method of eliminating their host's unnecessary functions such as reproduction (unnecessary to the parasite, that is) while leaving the host enough brain, nervous system, and digestive tract to go on feeding.
I imagine if there were a Sacculina-type parasite for humans, we would soon lose our urge to play football or go swimming. We would lie in front of the TV all day long, stuffing ourselves with---wait a minute, here! Is it possible...?
Zimmer also describes the stratagems that potential hosts have evolved to eliminate, or at least confuse the parasites that view them as mobile homes with well-stocked refrigerators:
"Consider the leaf-rolling caterpillars. They're pretty ordinary insect larvae with one exception: they fire their droppings like howitzers...What on Earth could have driven the evolution of an anal cannon? Parasites could. When parasitic wasps home in on a larva such as the leaf-roller caterpillar, one of the best clues is the odor of their host's droppings...The intense pressure put on leaf-roller caterpillars by [parasitic] wasps has pushed the evolution of high-pressure fecal firing. By getting their droppings away from them, the caterpillars have a better chance of not being found by wasps."
Even plants have evolved defenses against parasites, usually by creating poisonous chemicals that the parasite ingests as it chomps on the plant. Some plants will even emit a scent that attracts predator wasps to the caterpillar that is munching on their leaves (so much for high-pressure fecal cannons).
Be sure to read Chapters seven and eight: "The Two-Legged Host; and "How to Live in a Parasitic World," and ponder the statement, "A parasite that has no self-regulation is going to put itself out of existence and may take its host with it."
Could we humans be considered parasitic to Earth, itself?
"Parasite Rex" has detailed footnotes, a "Further Reading and Selected Bibliography" section, and an index for those readers who would like to pursue this fascinating subject. Carl Zimmer has also written, "At Water's Edge" and is a frequent contributor to "Discover," "National Geographic," "Natural History," "Nature," and "Science."
Perhaps the biggest flaw in the book is the lack of diagrams and its minimal number of photos. One of the coolest things about parasites is how gross they are and I wanted to see more of them. Also the same parasites seemed to keep coming up as examples of everything. Perhaps there are only so many types of parasites so it just doesn't matter whether one discusses blood flukes of humans or some other animal. But the book makes bold statements about how much more diverse parasites are than so called "free living" organisms, so it seemed a bit weird to continually be presnted with the "usual suspects" as examples of each of the parasitic principles.
The writing is clear and well organized, but goes on too long and is repetitive in places. This would probably have been a better book if were 30 pages shorter. But that's a quibble.
On the whole, a very good book that should interest anyone interested in natural systems and evolution, and parasites in particular.

Book arrived in great condition, exactly as advertised.
El tema es aparentemente desagradable pero el autor nos ayuda a verlo como fascinante y muy interesante, de modo que puede leerse de un tirón.
