Body temperature stability observed in the whale sharks, the world’s largest fish Itsumi Nakamura, Rui Matsumoto, Katsufumi Sato ABSTRACT: It is generally assumed that the body temperature of large animals is less likely to change due to their large body size, resulting in a high thermal inertia and a smaller surface area to volume ratio.
Hg and Se composition in demersal deep-sea fish from the North-East Atlantic Guilherme Teixeira, Joana Raimundo, Joana Goulart, Valentina Costa, Gui M. Menezes, Miguel Caetano, Mário Pacheco, Ines Martins ABSTRACT: It has been emphasized that seafood consumers may have a higher risk of mercury (Hg) exposure. Nevertheless, the co-occurrence of selenium (Se) in organisms may

Methylmercury levels in commercially harvested spiny dogfish (squalus acanthius) from off the coast of massachusetts George A. Maynard, Zofia Baumann ABSTRACT: Spiny Dogfish are small sharks that are harvested for seafood, primarily off the Eastern Seaboard of the United States. For the purposes of establishing seafood consumption advisories with regards to methylmercury (MeHg) content, the
Implications of life history uncertainty when evaluating status in the Northwest Atlantic population of white shark (Carcharodon carcharias) Heather D. Bowlby, A. Jamie F. Gibson ABSTRACT: To effectively protect at‐risk sharks, resource managers and conservation practitioners must have a good understanding of how fisheries removals contribute to changes in abundance and how regulatory restrictions may
Chondrichthyans as an umbrella species-complex for conserving South African biodiversity GJ Osgood, ME McCord, JK Baum ABSTRACT: Conservation surrogates, such as umbrella and flagship species, could help focus South Africa’s limited resources for research and management and enhance the conservation gains from marine protected areas (MPAs). Sharks, rays and chimaeras (Chondrichthyes), which are charismatic and
Using fisheries data to model the oceanic habitats of juvenile silky shark (Carcharhinus falciformis) in the tropical eastern Atlantic Ocean Jon Lopez, Diego Alvarez-Berastegui, Maria Soto, Hilario Murua ABSTRACT: Investigating the relationship between species and environmental conditions is key for the correct management of highly migratory large pelagic species like silky shark (Carcharhinus falciformis). This
Vision in sharks and rays: Opsin diversity and colour vision Nathan S.Hart ABSTRACT: The visual sense of elasmobranch fishes is poorly studied compared to their bony cousins, the teleosts. Nevertheless, the elasmobranch eye features numerous specialisations that have no doubt facilitated the diversification and evolutionary success of this fascinating taxon. In this review, I highlight
