Antarctic octopod beaks as proxy for mercury concentrations in soft tissues
International audience As the role of mercury is poorly known in Southern Ocean biota, the total mercury (T-Hg) concentrations were evaluated in upper/lower beaks, digestive gland, gills and mantle muscle of Adelieledone polymorpha and Pareledone turqueti, two of the most abundant octopod species ar...

Beaks had the lowest T-Hg concentrations (A. polymorpha: [T-Hg]Upper= 27.2±12.9 ng•g-1 and [T-Hg]Lower= 27.5±20.0 ng•g-1 P. turqueti: [T-Hg]Upper= 34.6±13.9 ng•g-1 and [T-Hg]Lower= 56.8±42.0 ng•g-1), followed by gills and muscle. The highest values were recorded in the digestive glands (A. polymorpha: 251.6±69.7 ng•g-1 P. turqueti: 347.0±177.0 ng•g-1). Significant relationships were found between the concentrations of T-Hg in the beaks and muscle of A. polymorpha (T-Hg in muscle is 10 times higher than in beaks). This study shows that beaks can be used as proxy for T-Hg in muscle for some octopod species, and a helpful tool for estimating total Hg body burden from beaks.
