...Jamie Baldwin; Sönke Johnsen SUMMARY In the blue crab, Callinectes sapidus , claw color varies by sex, sexual maturity and individual. Males rely in part on color cues to select appropriate mates, and these chromatic cues may be perceived through an opponent interaction between two photoreceptors...

... ) in the female blue crab, Callinectes sapidus . We found that visual acuity decreases substantially in the days prior to molting and is gradually recovered after molting. Four days prior to molting, α min was 1.8 deg ( N =5), a value approximating the best possible acuity in this species. In the 24 h before...

...Lindy K. Thibodeaux; Karen G. Burnett; Louis E. Burnett SUMMARY Callinectes sapidus (Rathbun), the Atlantic blue crab, commonly harbors low to moderate amounts of bacteria in hemolymph and other tissues. These bacteria are typically dominated by Vibrio spp., which are known to cause mortality...

...Michiya Kamio; Matthew A. Reidenbach; Charles D. Derby SUMMARY The nature of the courtship signalling used by a species is shaped by many factors, one of which is its habitat. Male blue crabs, Callinectes sapidus , have a courtship display in which they elevate their body by standing high...

...Kristin M. Hardy; Bruce R. Locke; Marilia Da Silva; Stephen T. Kinsey SUMMARY The muscles that power swimming in the blue crab, Callinectes sapidus , grow hypertrophically, such that in juvenile crabs the cell diameters are <60 μm, whereas fibers of the adult crabs often exceed 600μm. Thus...

...Stephen T. Kinsey; Pragyansri Pathi; Kristin M. Hardy; Amanda Jordan; Bruce R. Locke SUMMARY Post-metamorphic growth in the blue crab entails an increase in body mass that spans several orders of magnitude. The muscles that power burst swimming in these animals grow hypertrophically...

... eight membrane-spanning regions, in agreement with previously suggested topologies. The α-subunit amino acid sequence is highly conserved among species, with the blue crab sequence showing 81–83 % identity to those of other arthropods and 74–77 % identity to those of vertebrate species. Quantitative RT...
