...Coen P. H. Elemans; Allen F. Mensinger; Lawrence C. Rome Sound communication is fundamental to many social interactions and essential to courtship and agonistic behaviours in many vertebrates. The swimbladder and associated muscles in batrachoidid fishes (midshipman and toadfish) is a unique...

...Tamara M. Rodela; M. Danielle McDonald; Patrick J. Walsh; Kathleen M. Gilmour SUMMARY Gulf toadfish, Opsanus beta , are one among a group of unusual teleosts that excrete urea as their predominant nitrogen end product in response to stressful conditions. Under conditions of crowding or confinement...

... by apical Cl – /HCO 3 – exchange, with HCO 3 – provided by transepithelial transport and/or by carbonic anhydrase-mediated hydration of endogenous epithelial CO 2 . Hydration of CO 2 also liberates H + ,which is transported across the basolateral membrane. In this study, gulf toadfish ( Opsanus beta ) were...

...John F. Barimo; Patrick J. Walsh SUMMARY Because urea is bioenergetically expensive to synthesize, few aquatic teleostean (bony) fish make or excrete much urea beyond early development and excrete the majority of nitrogenous waste as the readily diffusible ammonia. The gulf toadfish is one of a few...

...John F. Barimo; Shelby L. Steele; Patricia A. Wright; Patrick J. Walsh SUMMARY The marine gulf toadfish ( Opsanus beta ) is an unusual teleost fish as it is able to switch between ammoniotelism and ureotelism in response to a variety of laboratory conditions. The present study integrates field work...

... + indicate that the toadfish gill s relatively permeable to NH 4 + compared to the shark gill and other ‘tight’ epithelia, consistent with the general conclusion that marine teleost gills are relatively cation-‘leaky’. Computation of the relative roles of the three delimited pathways for ammonia efflux...
