In the use of common names for species, shrimp is applied to smaller species, particularly species that are dorsoventrally depressed (wider than deep) with a shorter rostrum. Behavior and reproduction: Two-year-old juveniles often gather by the hundreds or thousands to form spectacular mounds known as pods in shallow water. They range widely in latitude as well: in the high Arctic some crustaceans use the short summer to develop quickly through a generation, leaving dormant stages to overwinter. (17) Clots were allowed to form in samples of whole blood taken from the American horseshoe crab, Limulus polyphemus, in the absence and presence of dansylcadaverine (16), and were analyzed for their contents of N epsilon(gamma-glutamyl)lysine and gamma-glutamyl-dansylcadaverine.
