Spiral valve parasites of blue and common thresher sharks as indicators of shark feeding behavior and ecology

Spiral valve parasites of blue and common thresher sharks as indicators of shark feeding behavior and ecology Antonella Preti, Ken MacKenzie, Kate A. Spivey, Leslie R. Noble, Catherine S. Jones, Ralph G. Appy, Graham J. Pierce ABSTRACT: We documented the parasite faunas of the spiral valves of blue sharks Prionace glauca (L. 1758) and common

Body temperature stability observed in the whale sharks

Body temperature stability observed in the whale sharks

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

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.
