...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...

...Lucy M. Palmer; Max Deffenbaugh; Allen F. Mensinger SUMMARY Inductive neural telemetry was used to record from microwire electrodes chronically implanted into the anterior lateral line nerve of the oyster toadfish, Opsanus tau (L.). The lateral lines of free-ranging toadfish were stimulated...

...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...

...Teresa Modesto; Adelino V. M. Canário SUMMARY The swimbladder and associated sonic muscle of the Lusitanian toadfish Halobatrachus didactylus increase in size throughout life and are,respectively, 25% and 30% larger in type I (nest-holder) males than females,which may generate sexual differences...

...Ulrike E. Siebeck; Shaun P. Collin; Majid Ghoddusi; N. Justin Marshall SUMMARY The toadfishes Tetractenos hamiltoni and Torquigener pleurogramma (Tetraodontidae) possess occlusable yellow corneas. We examine the light transmission and location of the yellow/orange pigment throughout the cornea...

...Patrick J. Walsh; Gregory D. Mayer; Mónica Medina; Matthew L. Bernstein; John F. Barimo; Thomas P. Mommsen SUMMARY We characterized the expression of the nitrogen metabolism enzyme glutamine synthetase [GSase; L-glutamate: ammonia ligase (ADP-forming), E.C. 6.3.1.2] in tissues of the gulf toadfish...

... + 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...
