The natural world is filled with diverse—not to mention quirky and odd—animal behaviors. Consider the male praying mantis that continues to mate after being beheaded; the spiders, insects, and birds that offer gifts of food in return for sex; the male hip-pocket frog that carries his own tadpoles; the baby spiders that dine on their mother; the beetle that craves excrement; or the starfish that sheds an arm or two to escape a predator's grasp.

Headless Males Make Great Lovers and Other Unusual Natural Histories celebrates the extraordinary world of animals with essays on curious creatures and their amazing behaviors. In five thematic chapters, Marty Crump—a tropical field biologist well known for her work with the reproductive behavior of amphibians—examines the bizarre conduct of animals as they mate, parent, feed, defend themselves, and communicate. Crump's enthusiasm for the unusual behaviors she describes-from sex change and free love in sponges to aphrodisiac concoctions in bats-is visible on every page, thanks to her skilled storytelling, which makes even sea slugs, dung beetles, ticks, and tapeworms fascinating and appealing. Steeped in biology, Headless Males Make Great Lovers points out that diverse and unrelated animals often share seemingly bizarre behaviors—evidence, Crump argues, that these natural histories, though outwardly weird, are successful ways of living.

Illustrated throughout, and filled with vignettes of personal and scientific interest, Headless Males Make Great Lovers will enchant the general reader with its tales of blood-squirting horned lizards and intestine-ejecting sea cucumbers—all in the service of a greater appreciation of the diversity of the natural histories of animals.
Marty Crump is Adjunct Professor of Biology at Northern Arizona University and a Conservation Fellow of the Wildlife Conservation Society. A recipient of the Distinguished Herpetologist Award, she is coauthor of In Search of the Golden Frog, also published by the University of Chicago Press.

“Zoologists collect nature stories. We pull them out like worn bandannas at field-site campfires and conference socials, keeping lecture-hall sleepers awake. We hone our favorites to their finest edge and listen to those told by the masters, hoping to learn something new. Now there is an entire book of such inspiration in Marty Crump’s Headless Males Make Great Lovers. With short, descriptive sentences, Crump paints an impressionistic portrait of five fundamental aspects of animal existence: mating, parenting, feeding, self-defense, and communication. Stepping easily between her subjects as if they were golden frogs, Crump weaves together natural history, poetry, mythology, family memories, and good humor with appropriate amounts of drama and distance. Each chapter begins with the intriguing, moves to the bizarre, and ends with the most spectacular examples of animal lore, seasoned with experiences from academia, personal friendships, and an elegant grasp of evolutionary and behavioral biology. Regardless of one’s background, there is space at this campfire for all.”

— Stephen M. Shuster, coauthor of Mating Systems and Strategies

“Marty Crump has an unerring eye for bizarre and perplexing aspects of natural history.  She writes with great zest, using her carefully selected examples to show how natural selection has shaped all aspects of animal biology. With great clarity, she explains how even the strangest phenomena conform to the basic, simple laws of nature. This book is a bravura performance, based on a lifetime of careful observation of the earth’s fast-vanishing biodiversity.” —Tim Halliday, coeditor of Firefly Encyclopedia of Reptiles and Amphibians

 “From penis-gnawing slugs to tadpole-transporting frogs, Marty Crump’s Headless Males Make Great Lovers captivates readers with remarkable stories about animals and their bizarre behaviors. With examples ranging from sponges to elephant seals, the book covers all major aspects of animal behavior and will be of interest to scientists and laypersons. I am certain her stories will inspire many to pursue studies of natural history and behavior.”

— Maureen A. Donnelly, coeditor of Ecology and Evolution in the Tropics

"A marvelous introduction to the whys and wherefores of animal behavior..."
— Booklist

"It's not just about insect sex—though there is a lot of it here. Marty Crump's book is a trawl through the whole gamut of weird animal behaviours. Watch out for spine-anointing, toad-chewing hedgehogs; tortoises that stomp the ground to draw up worms; and the mantids of the title that mate more effectively once the female has bitten off their heads. With Crump's 30-plus years of experience in the field, this beautifully written and charmingly illustrated book combines acute observation with helpful explanation. Nature has never seemed so bizarre and splendid."
— Adrian Barnett, New Scientist

"Weird words have their fans; and so do weird moments in natural history. In this book, biologist Marty Crump celebrates animal diversity, with the emphasis on the bizarre. Her aim is to bring the stuff of scientific papers to the general public. She ranges widely, from elephant seals to bowerbirds. The headings include sex, of course, as well as eating, young-rearing and defensive behaviour. Who would believe that hedgehogs anoint themselves with toad venom as a defence? That rabbits eat their own dung? Or that sea slugs like group sex? The book grosses out, but also educates. Not for intelligent design proponents."
— LUCY SUSSEX, The Age (Melbourne, Australia)

"The author has written an unabashed natural history—a celebration of the oddities and weirdness that can be found in the world of animal behavior. . . .With luck, this book will stimulate some younger readers to develop an interest in behavioral science, a stated goal of the author, while also building a greater appreciation in readers of all ages for the diversity of life."—John Alcock, Quarterly Review of Biology

"[Crump's] greatest strength is her ability to interpret natural history with an evolutionary perspective; such popular science writing is rare and refreshing. Moreover, because she meticulously documents her sources in a bibliography of references consulted, her book can be extremely useful to instructors looking for examples to spice up a lecture in an introductory biology class.—May Berenbaum, Ecology

"This unnatural history of the diverse social and sexual practices of insects and animals makes you glad that you are not a slipper limpet, even though it spends most of its life engaged in group sex and changes sex regularly. Nobody has a worse life than emperor penguins which breed in temperatures as low as minus 95F (-70C) and in wind speeds that reach 120mph. Female spiders chew the heads off their mates during sex—but they're game guys so they find another mate which eats what's left of them. Do they care? They're just doing what a guy's gotta do."
— Iain Finlayson, Times UK

"Crump has compiled a book of odd and icky tales. . . . What Crump has done is monumental of a sort--taking dry, eye rolling, yawn-generating technical scientific observations and making them fun for the general audience. These are the types of chronicles that Robert Ripley . . . made young, wide-eyed, budding scientists drool over in his Believe It or Not! challenge. . . . The book is packed with science, but more importantly, it's a lot of fun. Enjoy!"—Biology Digest
— Biology Digest

"Crump starts with sex but then explores other natural phenomena with an engaging down-to-earth approach that will keep you turning the pages from blood meals to legs modified into fangs to pheronomes as alarm signals. It's a great read."
— Sharon Wooten, The Olympian

"The combination of bizarre facts and rational, evolution-based explanations will make this an ideal book for an intelligent, nature-obsessed teenager (or, indeed, any-ager). I wish I could have read it 50 years ago. . . . We are living at a time of exponential growth in zoological knowledge, and inspired popularizers like Marty Crump . . . are needed to interpret the new findings for the rest of us."
— Nicholas Gould, International Zoo News
