The Horseshoe Crab
For many, the horseshoe crab is a childhood acquaintance, first introduced by a fierce-looking shell on a sandy beach.
For ecologists, the horseshoe is an important creature a vastly adaptable generalist that predates most species on the planet, with a lifecyle that is interlocked with other animals.
For the scientist, the limuli are an intriguing puzzle, offering insights into evolution, bacteria, vision and species- interdependence.

In 2009 ERDG launched its “Protecting Health” initiative to bring awareness to the growing threat to the three Asian horseshoe crab species as a result of excessive and lethal harvesting practices by the endotoxin detection industry engaged in the production of Tachypleus amoebocyte lycate (TAL). The intent of this initiative is to delineate the problems and to raise awareness of the possible implications for the global health industry, and provide tools to promote communication regarding how the pharmaceutical industry can become a driving force behind the conservation of the worlds four horseshoe crab species.

The Science and Conservation of Horseshoe Crabs
Building on the success of the 2011 International Workshop on the Science and Conservation of Asian Horseshoe Crabs held in Hong Kong, and the 2007 International Symposium on the Science and Conservation of Horseshoe Crabs held in New York, USA, the third International Workshop on the Science and Conservation of Horseshoe Crabs was held in Sasebo City, Nagasaki, Japan in 2015.
