Abstract

Horeshoe crabs "Limulus polyphemus" are remarkable ‘living fossils’ which have unique blood cells (amebocytes) that are used to test human vaccines for bacterial contamination. In the 1950’s, scientists at the Marine Biological Laboratory in Woods Hole, Massachusetts, not only discovered amebocytes but also found that they had special properties. If the amebocytes came into contact with bacteria, they would instantly coagulate around the bacteria and attack it. The Woods Hole scientists took this unique property of horseshoe crabs and developed a test for bacterial contamination using a horseshoe crab blood derivative called Limulus Amebocyte Lysate (LAL).

This article describes discusses the medical, economic, and ecological importance of the horseshoe crab. 'Project Limulus' is a research and community project which is working toward protecting the population of the horshoe crab.
