Summary
A number of marine animals were collected off Elephant Island (South Shetland Islands) and analyzed for fluoride (mg/kg wet weight). In fish muscle from six Antarctic species the content was low (approx. 2) not exceeding the content of fishes from other waters. In bone-tissue a concentration of 616–1207 was found. In some benthic living animals the amount of fluoride (determined in the whole body) was different depending on the species investigated. Low amounts of approx. 10 were encountered in a pycnogonid, an octopodid and a polychaet. Very high values of 200–600 were determined in isopods, amphipods, ophiuroids and asteroids, these concentrations exceeded sometimes the value found in Antarctic krill.
