... Neohelice granulata , a grapsid crab, to show that there are significant differences between the crabs' escape responses in the field compared with those previously documented in laboratory experiments. These differences are consistent with contextual adjustments such as the availability of a refuge...

...Jonathon H. Stillman; George N. Somero ABSTRACT We examined physiological and biochemical responses to temperature and aerial exposure in two species of intertidal porcelain crabs (genus Petrolisthes ) that inhabit discrete vertical zones. On the shores of the Northeastern Pacific, P. cinctipes...

...Clifford A. Hui ABSTRACT Video analyses of crabs walking on smooth and rocky terrains when in air and when submerged in water were conducted. Modifications of walking in the two environments, between which the animal’s weight changes sixfold, are consistent with the goals of maximizing ease...

... crabs exercise respiration circulation treadmill. Underwater locomotion, often involving slow-speed walking, is one of the characteristic features of marine Brachyura. Despite this, physiological changes during such activities have been studied in only a few brachyuran species ( Houlihan...

...Michael P. Nusbaum; Eve Marder ABSTRACT The distribution of red pigment concentrating hormone (RPCH)-like immuno-reactivity (RPLI) in the stomatogastric nervous system of the crab, Cancer borealis , was studied using whole-mount immunocytochemistry. RPLI was seen in neuropilar processes...
