...D. Michelle McComb; Stephen M. Kajiura SUMMARY The visual fields of elasmobranch fishes are not well characterized even though this is a fundamental element of the visual system. The batoid fishes(skates, rays) form a monophyletic clade within the subclass Elasmobranchii and exhibit a broad range...

... of the external environment. A 779 bp cDNA for a putative skate kidney urea transporter (SkUT) was cloned, sequenced and found to display relatively high identity with facilitated urea transporters from other vertebrates. Northern analysis using SkUT as a probe revealed three signals in the kidney at 3.1, 2.8...

...Christopher D. Moyes; Thomas W. Moon; James S. Ballantyne ABSTRACT The mechanism responsible for the osmotic sensitivity of sarcosine oxidation by liver mitochondria from the little skate, Raja erinacea Mitchill, is examined. Assay medium tonicity, rather than a solute effect (urea...
