Biology and Conservation of Horseshoe Crabs
Posted on 2010-03-16

More By John T. Tanacredi, Mark L. Botton, David Smith The four living species of horseshoe crabs face a set of growing threats to their survival, including the erosion and/or man-made alteration of essential spawning habitat, coastal pollution, and overfishing. Horseshoe crabs are “living fossils”, with a more than 200 million year evolutionary history. Their blood provides a reagent, known as Limulus amebocyte lysate or LAL, that clots in the presence of minute quantities of bacterial endotoxin; the LAL test is the state-of-the-art methodology used to ensure that pharmaceuticals and surgical implants are free of contamination. Horseshoe crabs are an integral part of the food web in coastal marine ecosystems, and their eggs provide essential food for shorebirds in the Delaware Bay estuary each spring. The commercial fishery for horseshoe crabs, which utilizes animals for bait, contributes to the economies of coastal communities. To thank me use this links!
