Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs. [PDF]
Environ Microbiol RepHere we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing. [PDF]
Anim GenetABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Sharks and their relatives: can their past help predict their future?
Frontiers in Marine Science, 2023 Elasmobranchs (i.e., sharks, skates, and rays) have survived five mass extinction events and changed relatively little throughout their ~450-million-year evolutionary history. Therefore, elasmobranchs may provide critical evolutionary perspectives on how

Dental microwear texture analysis as a tool for dietary discrimination in elasmobranchs
Scientific Reports, 2021 As abundant and widespread predators, elasmobranchs play influential roles in food-web dynamics of marine communities. Clearly, these trophic interactions have significant implications for fisheries management and marine conservation, yet elasmobranch ...

Quantitative assessment of inner ear variation in elasmobranchs
Scientific Reports, 2023 Considerable diversity has been documented in most sensory systems of elasmobranchs (sharks, rays, and skates); however, relatively little is known about morphological variation in the auditory system of these fishes.

Age and growth of Zapteryx brevirostris (Elasmobranchii: Rhinobatidae) in southern Brazil [PDF]
, 2018 Age and growth studies are fundamental to successful fisheries management. Zapteryx brevirostris (Muller & Henle, 1841) is distributed off the Brazilian continental shelf and this species is assessed as "Vulnerable" in the Red List of the International ...

Osmoregulation in Elasmobranchs [PDF]
American Zoologist, 1977 Osmoregulatory mechanisms were examined in major groups of fishes including hagfish, holocephalans, elasmobranchs, the coelacanth, and ray-fin fishes. Four main patterns of body fluid composition emerged. These represent the three main osmoregulatory processes in the marine environment and the one in fresh water.
