Horseshoe Crab Spawning Activity After Beach Nourishment

New York: Beach nourishment is a common shoreline protection method where sediment that has been eroded is replaced, typically using sediment dredged from offshore. To test its efficacy, a team of researchers led by Dr. Mark Botton from Fordham University investigated how beach nourishment projects affect horseshoe crab spawning. The study was conducted at Plumb Beach near the mouth of Jamaica Bay in Brooklyn, New York. This site provided a good study location because it has a history of beach nourishment projects. download the pdf.


Bird Flu Hot Spot: Scientists Track Virus in Huge Migration

New Jersey: Huge flocks of famished birds scour the sands of Delaware Bay for the tiny greenish eggs an army of horseshoe crabs lays every spring. It’s a marvel of ecology as shorebirds migrating from South America to the Arctic time a stop critical to their survival to this mass crab spawning. It’s also one of the world’s hot spots for bird flu a bonanza for scientists seeking clues about how influenza evolves so they just might better protect people. download the pdf.

Horseshoe Crabs Living Through A Crisis

Global: In a new study (Shu et al. 2018), we were able to record horseshoe crab tracks from a succession of rocks that spanned the great Permian-Triassic (PT) mass extinction 252 million years ago. Limulids (of course) survived, but we had questions to ask about whether the devastating environmental changes associated with the mass extinction had in any way knocked them sideways. download the pdf.

Commission Approves Modern Animal-Free Testing for Drugs

India: In a step that would spare animals from suffering due to drug experiments, the Indian Pharmacopoeia Commission has approved modern, animal-free tests for drug manufacturers. In the 2018 edition of Indian Pharmacopoeia, that provides guidelines on tests for drugs manufactured and marketed in India, the IPC has replaced the pyrogen test carried out on rabbits and the abnormal toxicity test carried out on guinea pigs and mice with tests that can be done in test tubes. download the pdf.

Digital Dissection: CT Scans Reveal New Muscles in Horseshoe Crabs

Australia: A team of students from the University of New England (UNE) in Australia conducted CT scans of a dried horseshoe crab carcass from the
University of New England Natural History Museum as well as of fresh appendages, and then used the scans to create a 3-D model of its muscular system. The 3-D image revealed some new muscular structures in the horseshoe crab appendages. download the pdf.

Young Voices™ Horseshoe Crabs in the Arts 2018

Delaware: Our 2018 contest year received 310 entries from Mauritius, France, and the USA. Our judges selected 10 of the most compelling artworks from each grade level that entered. As always, the task was challenging, for all forms of personal expression are, by their very nature, an honest reflection of the heart within. Since the program’s inception in 1998, the Young Voices that give this program life has grown from a few hundred to many thousands around the world. We celebrate these young environmental stewards, whose compassion for the conservation of this remarkable species, expressed through art, has elevated and transformed our perception of this often-misunderstood marine.

The ‘Crab’ That Might Have Saved Your Life

Global: Whatever the future holds, the horseshoe crab is perhaps more adept than most species at seeing it through. “Everything it does has a purpose and that purpose is survival,” Glenn Gauvry said. “They’re quite adaptable to an awful lot of things. But we [man] move too fast, so, yeah, we end up being the big challenge.” download the pdf.


Horseshoe Crabs Are at Risk—So Endotoxin Tests Are, Too

With a growing focus on the development of innovative biotherapeutics that have a higher risk of endotoxin contamination and the advent of personalized medicine requiring individual drug testing, endotoxin testing workflows are becoming more important than ever. However, relying purely on the horseshoe crab to provide this crucial safety test simply isn’t sustainable. In this article, we consider why protection of the horseshoe crab is so important for our own health, and how the validation of alternative endotoxin testing approaches offers a more sustainable solution. download the pdf.

Volunteers’ Fence Saves Thousands of Horseshoe Crabs

Delaware: According to organizers, a scheme to close off a horseshoe crab “kill zone” on Pickering Beach has been a thumping success. In late April a partnership including DNREC, Pickering Beach residents and the Ecological Research & Development Group (ERDG) — a 501(c)3 non-profit organization focused on horseshoe crab conservation efforts — installed a 350-foot wooden temporary storm fence across a stretch of beach to prevent deadly horseshoe crab strandings. download the pdf.

Inside the Biomedical Revolution to Save Horseshoe Crabs and the Shorebirds That Need Them

New Jersey: The horseshoe crab plays a vital, if little-known, role in the life of anyone who has received an injectable medication. An extract of the horseshoe crab’s blood is used by the pharmaceutical and medical-device industries to ensure that their products, e.g., intravenous drugs, vaccines, and medical devices, are free of bacterial contamination. No other test worked as easily or reliably for this purpose—until now. download the pdf.

Group Aims to Halt Horseshoe Crab ‘Kill Zone’ at Pickering Beach

Delaware: In recent years, regulations have been tightened on these practices. The changes have resulted in more population stability, but there is more people can do to ease the plight of the 450 million-year-old species says Mr. Gauvry. On Thursday, a collaborative experimental project between ERDG, the Pickering Beach community and DNREC to build a storm fence across an identified “horseshoe crab kill zone” is one such effort. download the pdf.


March of the Horseshoe Crabs

Delaware: The horseshoe crab was walking the ocean floor long before the first T-Rex was hatched. In fact, this ungainly arthropod has survived half a billion years. And yet, one of the oldest living species on the planet doesn’t have a week dedicated to it on the Discovery Channel, or its own Facebook page (like Mary Lee, the great white shark). Dismissed by many as ugly and useless, this Rodney Dangerfield of sea creatures often “gets no respect.” download the pdf.


New ‘Living Fossil’ Program at Refuge Highlights Role of Species

Florida: The J.N. “Ding’ Darling National Wildlife Refuge is offering a new program on horseshoe crabs. One of the educational tools for the program that the refuge staff is excited to utilize is the model, developed by the Ecological Research & Development Group in Delaware. The world’s first museum-grade model of a female horseshoe crab, it shows the species’ exterior surfaces complete in detail. The top of the model separates from the bottom of it to reveal the internal organs – colored for easier identification – egg distribution and circulatory system, providing a view never before available. “It greatly enhances the program,” Wettstein said. “It has added so much to it.” The refuge was able to acquire the tool through a donation by a donor. download the pdf.
