Summary: As fish-eating predators at the top of the marine food chain, elephant seals accumulate high concentrations of mercury in their bodies. A new study shows that elephant seals shed significant amounts of mercury during molting, resulting in elevated concentrations of the toxic metal in coastal waters near the elephant seal rookery at Año Nuevo State Reserve.
