Leeches are parasites that feed off the blood of many animals, including people. Living in freshwater, salt water, and even on land, these bloodsuckers are always looking for their next meal. Find out about the many kinds of leeches, their anatomy, habitats, and favorite meals. A fact spread highlights some of the more disgusting features of leeches.

“A witty, scientifically accurate, and often intensely creepy exploration of sanguivorous creatures.”—San Francisco Chronicle “Bill Schutt turns whatever fear and disgust you may feel towards nature’s vampires into a healthy respect for evolution’s power to fill every conceivable niche.”—Carl Zimmer, author of Parasite Rex and Microcosm: E. coli and the New Science of Life For centuries, blood feeders have inhabited our nightmares and horror stories, as well as the shadowy realms of scientific knowledge. In Dark Banquet, zoologist Bill Schutt takes us on a fascinating voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that blood feeders, from bats to bedbugs, are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even worthy of conservation. Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon. Enlightening and alarming, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.
Los Angeles Times Book Prize Finalist: A “compelling chronicle” of the science, politics, and business of blood (The Wall Street Journal). Blood carries life, yet the sight of it makes people faint. It is a waste product and a commodity pricier than oil. It can save lives and transmit deadly infections. Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquitousness, the few tablespoons of blood discharged by 800 million women are still regarded as taboo: menstruation is perhaps the single most demonized biological event. Rose George, author of The Big Necessity, takes us from ancient practices of bloodletting to the breakthrough of the “liquid biopsy,” which promises to diagnose cancer and other diseases with a simple blood test. She introduces Janet Vaughan, who set up the world’s first system of mass blood donation during the Blitz, and Arunachalam Muruganantham, known as “Menstrual Man” for his work on sanitary pads for developing countries. She probes the lucrative business of plasma transfusions, in which the US is known as the “OPEC of plasma.” And she looks to the future, as researchers seek to bring synthetic blood to a hospital near you. Spanning science and politics, individual’s stories and global epidemics, Nine Pints reveals our life’s blood in an entirely new light. One of Bill Gates’ Recommended Summer Reading Titles “Stellar . . . An informative, elegant, and provocative exploration of the life-giving substance . . . A wondrously well-written work.” —Booklist (starred review) Both fascinating and informative . . . George packs her book with the kinds of provocative, witty, and rigorously reported facts and stories sure to make readers view the integral fluid coursing through our veins in a whole new way.” —Kirkus Reviews (starred review) “George charges down wholly unexpected avenues of medical history and global injustice, leaving the reader by turns giddy and appalled. And always, always in awe of the writing.” —Mary Roach, author of Grunt: The Curious Science of Humans at War “A very good book.” —The New York Times
WINNER - Best American Play, Obie Awards 2018 In 1920, the Russian writer Isaac Babel wanders the countryside with the Red Cavalry. In 1990, a mysterious KGB agent spies on a woman in Dresden and falls in love. In 2010, an aircraft carrying most of the Polish government crashes in the Russian city of Smolensk. Set in Russia over the course of ninety years, this thrilling and epic new play by Rajiv Joseph traces the stories of seven men and women connected by history, myth and conspiracy theories.
Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.
Takes a close look at what we dislike about each of 10 unpopular animals, and then presents the flip side: these very same animals are often smart, helpful to humans and the environment, or inspiring to scientists.
Medicinal leech therapy has undergone a renaissance in recent years, both in terms of how well the effects of using leeches are understood,and in the discovery of new clinical applications that have resulted in remarkable outcomes. This timely book introduces the basic principles of using leeches in clinical practice, and clearly sets out the methodology and potentialapplications. Emphasis is given to those areas of medicine where scientific studies have already provided firm evidence of success -- treatment of arthrosis and pain is already benefiting from this highly effective therapy.Excellent instructions for the use of leeches cover the full spectrum of possible applications, while the encouraging new developments in research are also addressed. This valuable guide for physicians to this important therapy comes from the acknowledged experts in the field.
This book summarizes the status quo of the knowledge about the biodiversity in terrestrial, freshwater, and marine animals that live in Japan. Consisting of some 6,800 islands that are arrayed for approximately 3,500 km from north to south, the Japanese archipelago has a complex history in a paleogeographic formation process over time and harbors rich flora and fauna. This work will contribute to establishing a general biogeographic theory in archipelagoes around continental shelves. Facing the ongoing extinction crisis, one of the most important tasks for our generation is to bequeath this precious natural heritage to future generations. As the first step toward this goal, a species list has been compiled through solid, steady alpha-taxonomic work in each taxon. Furthermore, the phylogeography and population genetic structure for each species is elucidated for deeper understanding of the local fauna, the scientific results of which should be the basis for establishing conservation policies and strategies. Also the problem of alien or introduced species is investigated as another threat to the native fauna.Each of the 27 chapters is written by the most active specialist leading the field, thus readers can acquire up-to-date knowledge of the animal species diversity and their formation process of Japanese animals in the most comprehensive form available. This book is recommended for researchers and students who are interested in species diversity, biogeography, and phylogeography.
