Leeches Eat Blood

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.

There are over 650 different types of leeches. And most want to suck your blood! These real-life vampires are nocturnal, like dark places, and only come out when they get thirsty! But can these bloodsuckers actually help humans? The ancient Egyptians may have been on to something! Readers learn about the habitats, history, and medical uses of the bloodsucking leech. Full-color photographs offer an up close view of these thirsty worms, and fact boxes share more details about their fascinating lives.

Examines animals that feed on blood, including mosquitoes, vampire bats, lice, leeches, lampreys, and fleas, and looks at their anatomy, behavior, and interactions with people.

“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.

An eye-opening exploration of blood, the lifegiving substance with the power of taboo, the value of diamonds and the promise of breakthrough science 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, is renowned for her intrepid work on topics that are invisible but vitally important. In Nine Pints, she takes us from ancient practices of bloodletting to the breakthough 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, stories and global epidemics, Nine Pints reveals our life's blood in an entirely new light. Nine Pints was named one of Bill Gates recommended summer reading titles for 2019.

The animal world is immensely diverse, and our understanding of it has been greatly enhanced by analysis of DNA and the study of evolution and development ('evo-devo'). In this Very Short Introduction Peter Holland presents a modern tour of the animal kingdom. Beginning with the definition of animals (not obvious in biological terms), he takes the reader through the high-level groupings of animals (phyla) and new views on their evolutionary relationships based on molecular data, together with an overview of the biology of each group of animals. The phylogenetic view is central to zoology today and the volume will be of great value to all students of the life sciences, as well as providing a concise summary for the interested general reader. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Examines such cold-blooded bloodsucking animals as the leech, lamprey, tick, and flea.
