A glance underneath the carapace reveals six pairs of appendages for locomotion and foraging and so-called book gills — slim sheets of tissue using a leathery include — useful for respiration and propulsion.
“The amebocyte is definitely an all-objective cell.

Bang had carried out earlier investigation on horseshoe crab blood clotting. Levin was to carry on in that vein, conducting essential exploration into similarities among the horseshoe crab’s blood mobile — the amebocyte — and human platelets, which support blood clot.

The presence of endotoxins in the blood could cause the fast onset of fever, among the body’s protective responses to a international invader.

More experiments supported Levin’s hunch — endotoxins prompted blood coagulation. He also figured out that clotting was the result of an enzymatic response. When a clot types, the amebocyte unleashes other components that perform to wipe out the supply of infection, Levin points out.
