"For those unaware—as I was until I read this book—that Mark Twain was one of America's early animal advocates, Shelley Fisher Fishkin's collection of his writings on animals will come as a revelation. Many of these pieces are as fresh and lively as when they were first written, and it's wonderful to have them gathered in one place." —Peter Singer, author of Animal Liberation and The Life You Can Save “A truly exhilarating work. Mark Twain's animal-friendly views would not be out of place today, and indeed, in certain respects, Twain is still ahead of us: claiming, correctly, that there are certain degraded practices that only humans inflict on one another and upon other animals. Fishkin has done a splendid job: I cannot remember reading something so consistently excellent."—Jeffrey Moussaieff Masson, author of When Elephants Weep and The Face on Your Plate "Shelley Fisher Fishkin has given us the lifelong arc of the great man's antic, hilarious, and subtly profound explorations of the animal world, and she's guided us through it with her own trademark wit and acumen. Dogged if she hasn't." —Ron Powers, author of Dangerous Water: A Biography of the Boy Who Became Mark Twain and Mark Twain: A Life

Introduces the physical characteristics, habitat, and survival techniques of the kangaroo.

Have you ever wondered just how far animals can jump? From tiny grasshopper hurdles and coyote vaults to the best pouncer of all: understanding numbers and distance is easy with this fun book of animal facts! None of the animals can match the world-record-holding snow leopard! At the end, kids will discover how many jumps it would take each one to go all around the globe.

How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.

Animals have evolved remarkable biomechanical and physiological systems that enable their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of animal movement through a broad comparative and integrative approach, including basic mathematics and physics, examination of new and enduring literature, consideration of classic and cutting-edge methods, and a strong emphasis on the core concepts that consistently ground the dizzying array of animal movements. Across scales and environments, this book integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion. This second edition has been thoroughly revised, incorporating new content on non-vertebrate animal locomotor systems, studies of animal locomotion that have inspired robotic designs, and a new chapter on the use of evolutionary approaches to locomotor mechanisms and performance.

What do all the animals in this book have in common? They jump!

Animals have existed on Earth for many hundreds of millions of years. In that time they have evolved into a great variety of forms, exploiting nearly every habitat the planet has to offer. In the dark depths of the oceans, in the seemingly inhospitable Polar Regions, in the driest deserts, even within the bodies of other animals, there are animal species that have developed unique and extraordinary means of surviving and thriving. Extraordinary Animals: An Encyclopedia of Curious and Unusual Animals is an exploration of those members of the animal kingdom who possess strange and bizarre adaptations that allow them to survive in the most extreme environments, or whose complex lives can only be said to be bewildering. From the tar-baby termite to the blue whale, from the harpy eagle to the naked mole rat, these species reflect the exceptionally broad spectrum of life, showing just how diverse the animal kingdom is. Extraordinary Animals has been thoroughly researched for scientific accuracy, but is accessibly written in everyday language. Each entry includes a description of the animal, an explanation of its odd behavior, other interesting scientific and trivial facts, and black and white illustrations. In addition, a fun and interactive Go Look section encourages readers to go look for the animals in the outside world.

This book provides a clear foundation, based on physical biology and biomechanics, for understanding the underlying mechanisms by which animals have evolved to move in their physical environment. It integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion. The author also communicates a sense of the awe and fascination that comes from watching the grace, speed, and power of animals in motion. Movement is a fundamental distinguishing feature of animal life, and a variety of extremely effective mechanical and physiological designs have evolved. Common themes are observed for the ways in which animals successfully contend with the properties of a given physical environment across diversity of life forms and varying locomotor modes. Understanding the common principles of design that span a diverse array of animals requires a broad comparative and integrative approach to their study. This theme persists throughout the book, as various modes and mechanisms of animal locomotion are covered. Since an animal's size is equally critical to its functional design, the effects of scale on locomotor energetics and mechanics are also discussed. Biewener begins by examining the underlying machinery for movement: skeletal muscles used for force generation, skeletons used for force transmission, and spring-like elements used for energy savings. He then describes the basic mechanisms that animals have evolved to move over land, in and on the surface of the water, and in the air. Common fluid dynamic principles are discussed as background to both swimming and flight. In addition to discussing the locomotor mechanisms of complex animals, the locomotor movement of single cells is also covered. Common biochemical features of cellular metabolism are then reviewed before discussing the energetic aspects of various locomotor modes. Strategies for conserving energy and moving economically are again highlighted in this section of the book. Emphasis is placed on comparisons of energetic features across locomotor modes. The book concludes with a discussion of the neural control of animal locomotion. The basic neurosensory and motor elements common to vertebrates and arthropods are discussed, and features of sensori-motor organization and function are highlighted. These are then examined in the context of specific examples of how animals control the rhythmic patterns of limb and body movement that underlie locomotor function and stability.
