Protecting Horseshoe Crab Habitat
Each spring adult horseshoe crabs migrate from deep bay waters and the Atlantic continental shelf to intertidal sandy beaches to spawn. Horseshoe crabs are an important food source for migrating shorebirds that feed on the eggs, for migrating fish that feed on the eggs and larvae and for Atlantic loggerhead turtles that feed on horseshoe crabs while using the Chesapeake Bay as a summer nursery ...
متن کاملHemocyanin of the Horseshoe Crab, Limzdus polyphemus
The high molecular weight hemocyanin found in the hemolymph of the horseshoe crab, Limulus polyphemus, is composed of at least eight different kinds of subunits. Ion exchange chromatography at high pH in the presence of EDTA yields five major zones, hemocyanins I to V, three of which are electrophoretically heterogeneous. The subunits have similar molecular weights, 65,000 to 70,000, and their ...
متن کاملUsing the Horseshoe Crab, Limulus Polyphemus, in Vision Research
The American horseshoe crab, Limulus Polyphemus is one of the oldest creatures on earth, and the animal continues to play an indispensable role in biomedical research. Not only does their blood contain special cells that scientists use to detect bacteriotoxins in our medicines, but their eyes also contain a neural network that has provided much insight about physiological processes operating in...
متن کاملCyclic GMP in lateral eyes of the horseshoe crab Limulus
In Limulus photoreceptors, light induces a depolarization. The gating mechanism of the cation channels involved is not understood but evidence exists that cyclic nucleotides may act as ligands. Using an antiserum against a cGMP-protein conjugate, we found strong immunoreactivity localized to the light-sensitive rhabdoms of lateral eye photoreceptors. In homogenated tissue, the cGMP concentratio...
متن کاملCompanions at a Distance: Technoscience, Blood, and the Horseshoe Crab
In this paper we present a particular history of Limulus polyphemus, the horseshoe crab, as a means of expanding on Haraway’s notion of companion species. Drawing on accounts of the horseshoe crab’s role, on the one hand, in work of the Serological Museum at Rutgers University that spanned the 1940s to the 1970s, and, on the other, in the development of the limulus amebocyte lysate test, we tra...
