Book Description
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.

High Tide for Horseshoe Crabs

High Tide for Horseshoe Crabs PDF Author: Lisa Kahn Schnell
Publisher: Charlesbridge Publishing
ISBN: 1580896049
Category : Juvenile Nonfiction
Languages : en
Pages : 40

Book Description
Horseshoe crabs, shorebirds, and humans converge in a frenzy of activity. Every spring millions of horseshoe crabs crawl to the beaches of Delaware Bay to lay their eggs. But they aren’t the only ones crowding ashore. Flocks of shorebirds migrating north from South America stop to feed on the horseshoe crab eggs. People also flock to the scene. Scientists and tourists turn out to see the spectacle and learn more about the creatures that call this habitat home for a few weeks. Alan Marks' gorgeous paintings bring the reader down to the shoreline to observe this exciting annual event that interconnects species in a web of life and an ancient food chain.

Crab Wars

Crab Wars PDF Author: William Sargent
Publisher: University Press of New England
ISBN: 1611687160
Category : Nature
Languages : en
Pages : 100

Book Description
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.

Catch and Release

Catch and Release PDF Author: Lisa Jean Moore
Publisher: NYU Press
ISBN: 1479848093
Category : Social Science
Languages : en
Pages : 224

Book Description
The unexpected and fascinating interspecies relationship between humans and horseshoe crabs. Horseshoe crabs are considered both a prehistoric and indicator species. They have not changed in tens of millions of years and provide useful data to scientists who monitor the health of the environment. From the pharmaceutical industry to paleontologists to the fishing industry, the horseshoe crab has made vast, but largely unknown, contributions to human life and our shared ecosystem. Catch and Release examines how these intersections steer the trajectory of both species’ lives, and futures. Based on interviews with conservationists, field biologists, ecologists, and paleontologists over three years of fieldwork on urban beaches, noted ethnographer Lisa Jean Moore shows how humans literally harvest the life out of the horseshoe crabs. We use them as markers for understanding geologic time, collect them for agricultural fertilizer, and eat them as delicacies, capture them as bait, then rescue them for conservation, and categorize them as endangered. The book details the biomedical bleeding of crabs; how they are caught, drained of 40% of their blood, and then released back into their habitat. The model of catch and release is essential. Horseshoe crabs cannot be bred in captivity and can only survive in their own ecosystems. Moore shows how horseshoe crabs are used as an exploitable resource, and are now considered a “vulnerable” species. An investigation of how humans approach animals that are essential for their survival, Catch and Release questions whether humans should have divine, moral, or ethical claims to any living being in their path.
