Odobenus Rosmarus Rosmarus

Atlantic walrus (Odobenus rosmarus rosmarus) harvested at Igloolik and Hall Beach (Foxe Basin) and Inukjuak and Akulivik (eastern coast of Hudson Bay) and clams (Mya truncata) and cockles (Serripes groenlandicus) collected at Igloolik were analyzed for heavy metals and Se. Pb was high in walrus from both Hudson Bay and Foxe Basin compared with other marine mammals, but levels were higher in animals from Hudson Bay than Foxe Basin, showing a geographic trend of increasing concentration from north to south. In some tissues of clams, Pb was also high, up to 3 μg/g (wet weight). Hg levels in walrus were low compared with those in other Arctic marine mammals; in liver, Hg showed a geographic trend similar to Pb. Cd in liver and particularly in kidney of walrus was high compared with other Arctic marine mammals and was higher in those from Foxe Basin than Hudson Bay. Associations among metals and between metals and age were found in walrus that were also reported for other marine mammals, namely between Hg and Se in liver, Hg and Cd in liver, Hg and Cd with age in kidney, Cd with Zn in liver and kidney, and Hg and Se in liver with gender.

First Time

The Strait of Messina is located at the centre of the Mediterranean Sea and is considered a biodiversity hotspot and an obligatory seasonal passage for different pelagic species such as sharks, marine mammals, and billfishes. For the first time, in the Strait of Messina, our research group tagged a Mediterranean spearfish (Tetrapturus belone) using a pop-up satellite archival tag (PSAT). The observation of abiotic parameters (depth, light, and temperature) recorded by the PSAT confirmed that the tagged specimen was predated after about nine hours. The tag was then regurgitated 14 days after the tag deployment date. The analysis of collected data seems to indicate that the predator may be an ectothermic shark, most likely the bluntnose sixgill shark (Hexanchus griseus).
