Traveling from the Delaware Bay to the Florida Panhandle, this examination is a quest through the natural history and science behind one of nature's oldest and oddest survivors--the horseshoe crab. With ten eyes, five pairs of walking legs, a heart half the length of their bodies, and blood that can save a person's life, horseshoe crabs have been on this planet for 445 million years--since long before the dinosaurs arrived. This book explores their unique biology and sex life, explains their importance to medical science and migratory shorebirds, and introduces readers to the people who are working to study and protect them.

This book brings together 20 scientists who have worked on all aspects of horseshoe crab biology to compile the first fully detailed, comprehensive view of Limulus polyphemus. An indispensable resource, the volume describes behavior, natural history, and ecology; anatomy, physiology, distribution, development, and life cycle.

Surviving almost unmolested for 300 million years, the horseshoe crab is now the object of an intense legal and ethical struggle involving marine biologists, environmentalists, US government officials, biotechnologists, and international corporations. The source of this friction is the discovery 25 years ago that the blood of these ancient creatures serves as the basis for the most reliable test for the deadly and ubiquitous gram-negative bacteria. These bacteria are responsible for life-threatening diseases like menengitis, typhoid, E. coli, Legionnaire's Disease and toxic shock syndrome. Because every drug certified by the FDA must be tested using the horseshoe crab derivative known as Limulus lysate, a multimillion dollar industry has emerged involving the license to "bleed" horseshoe crabs and the rights to their breeding grounds. Since his youthful fascination with these ancient creatures, William Sargent has spent much of his life observing, studying, and collecting horseshoe crabs. As a result, he presents a thoroughly accessible insider's guide to the discovery of the lysate test, the exploitation of the crabs at the hands of multinational pharmaceutical conglomerates, local fishing interests, and the legal and governmental wrangling over the creatures' ultimate fate. In the end, the story of the horseshoe crab is a sobering reflection on the unintended consequences of scientific progress and the danger of self-regulated industries controlling a limited natural resource.

Horseshoe crabs, those mysterious ancient mariners, lured me into the sea as a child along the beaches of New Jersey. Drawn to their shiny domed shells and spiked tails, I could not resist picking them up, turning them over and watching the wondrous mechanical movement of their glistening legs, articulating with one another as smoothly as the inner working of a clock. What was it like to be a horseshoe crab, I wondered? What did they eat? Did they always move around together? Why were some so large and others much smaller? How old were they, anyway? What must it feel like to live underwater? What else was out there, down there, in the cool, green depths that gave rise to such intriguing creatures? The only way to find out, I reasoned, would be to go into the ocean and see for myself, and so I did, and more than 60 years later, I still do.

Presents a portrait of the Delaware Bay in the spring when a wide variety of animals, including minnows, mice, turtles, raccoons, and especially migrating shorebirds, come to feed on the billions of eggs laid by horseshoe crabs.

An illustrated guide to celebrating alternative futures today! Second Edition. Cardboard sculpting how-to, karaoke songbook, naturedrag theorization, 450-million-year-long love letter to horseshoe crabs, field guide to a different future--BLOODTIDE proposes exactly what we need in a form we never imagined: a new kind of holiday in homage to the ancient Horseshoe Crab. BLOODTIDE is drawn from the author's own need for new cultural practices and extended as an offering for anybody to use with hopes of contributing to collective liberation. It attempts queer futurity, without mythologies of settler innocence and with sustained recognition that time extends through our ancestors: recent ones and ancient. BLOODTIDE promotes horizontalist structure-building practices through pageantry, crabaoke, cardboard sculpting, feasting and other hands-on, locally oriented, commemorative & survivalist practices. BLOODTIDE posits that homage and attention to horseshoe crabs might further all repair efforts and other insufficient necessities for our collective and individual healing/transformation. "It is radical, it is wise, it is alive."--Agnes Borinsky "BLOODTIDE gifts us a river to wander down where we can drift away from the bullshit through the fugitivity of fun, fellowship and inter/trans species abolition."--bront" velez "Brimming with irreverence, delight and full-throated urgency on every page...there has never been a more compelling case to radically re-imagine our relationships to more-than-human animals and our environment. My family and I are plotting our BLOODTIDE activations already!"--Sarah Benson Literary Nonfiction. Essay. Hybrid. Poetics. Environmental Studies. LGBTQIA Studies. Art.

"The author considers interactions between horseshoe crabs and humans, through fieldwork conducted between 2012 and 2016 at urban beaches near New York City, nature preserves in Japan, and marine research sites in Florida, and interviews with conservationists, field biologists, ecologists, and paleontologists. She explores the interspecies relationship between humans and horseshoe crabs, and how they are meaningful to one another in specific ways as humans interpret them for understanding geologic time, use them for biomedical applications, collect them for agricultural fertilizer, eat them, and capture them as bait, and crabs make humans matter by revealing humans' vulnerability to endotoxins and fertilizing soil for human food. She examines how humans exploit crabs, depend on them, and consider their welfare, discussing issues related to the species health of the horseshoe crab, their sexual reproduction, the use of their endotoxins, and global warming, site fidelity, and reclamation projects."--Provided by publisher.

Two horseshoe crabs live together in a touch tank, give blood in a lab, swim together and mate in the sea.

Like a perfect day at the beach, Crab Moon leaves an indelible memory of a special adventure, and a quiet message about doing our part to preserve earth's oldest creatures. One June night, under the full moon, Daniel’s mother wakes him up to see the extraordinary sight of horseshoe crabs spawning on the beach, just as they have every spring for an awesome 350 million years. But when Daniel returns in the morning, he finds only one lonely crab, marooned upside down in the sand. Can he possibly save it? Like a perfect day at the beach, Crab Moon leaves an indelible memory of a special adventure between parent and child, and a quiet message about doing our part to preserve even earth’s oldest creatures. Back matter includes a note about horseshoe crabs.

Ancestors of horseshoe crabs date back over 450 million years. That’s before dinosaurs walked Earth! Readers will find out more about these intriguing arthropods—which aren’t even crabs!—and theories about why they survived while dinosaurs became extinct. They’ll learn about horseshoe crabs’ unique behaviors, how they’ve adapted over the years, and gain an overall appreciation for these magnificent marine creatures.
