... organisms are unable to escape. Many species of elasmobranchs are oviparous and deposit egg cases that remain in a fixed position on or near the seabed with development times ranging from months to over a year. The auditory sensitivity of elasmobranchs has been relatively understudied compared...

... in nitrogen-limited animals. Marine elasmobranchs are nitrogen limited as they require substantial amounts of this element to support urea-based osmoregulation. However, following antibiotic-induced depletion of the gut microbiome, elasmobranchs are known to experience a significant decline in circulating...

...Carolin Nieder; Jimmy Rapson; John C. Montgomery; Craig A. Radford ABSTRACT Auditory sensitivity measurements have been published for only 12 of the more than 1150 extant species of elasmobranchs (sharks, skates and rays). Thus, there is a need to further understand sound perception in more species...

...C. Michele Nawata; Patrick J. Walsh; Chris M. Wood In teleosts, a branchial metabolon links ammonia excretion to Na + uptake via Rh glycoproteins and other transporters. Ureotelic elasmobranchs are thought to have low branchial ammonia permeability, and little is known about Rh function...

... of high pressure, which may explain why its activity is not very obvious in the velocity recordings, as the highest velocity is recorded at the onset of ventricular contraction. Histological study confirms that there are cardiac muscle fibres in the wall of the conus of elasmobranchs, although...

...L Goldstein; CA Luer; PC Blum ABSTRACT The hearts of elasmobranchs, like those of other vertebrates, contain high concentrations of the β -amino acid taurine, which is thought to play an osmoregulatory role in cardiac tissue. Although mammals and certain invertebrates can synthesize taurine from...

D eff was calculated from O 2 uptake and in gill water and blood, using a modified Bohr integration technique.
