Kapitel 2: Arresting mantle formation and redirecting embryonic shell gland tissue by Platinum 2+ leads to body plan modifications in Marisa cornuarietis (Gastropoda, Ampullariidae) 6 Leonie Marschner 1 , Rita Triebskorn 1,2 ,Heinz-R. Köhler 1 1 Animal Physiological Ecology, Institute of Evolution and Ecology, Biology Department, University of Tübingen, Tübingen D-72072, Germany 2 Transfer Center for Ecotoxicology and Ecophysiology, Rottenburg 72108, Germany Abstract To evaluate the threat that anthropogenic substances pose to animals when they are emitted into the environment, tests like the invertebrate embryo toxicity test with the ramshorn snail Marisa cornuarietis have been developed. These tests are used to investigate substances like the heavy metal platinum (Pt) that is used in catalytic converters and is gradually released in car exhausts. In 2010, our group reported that high Pt concentrations cause body plan alterations in snails and prevent the formation of an external shell during M. cornuarietis embryogenesis. Now, this study presents scanningelectron micrographs and histological sections of platinum 2+ (Pt 2+ )-treated and untreated M. cornuarietis embryos and compares “normally” developing and “shell-less” embryos during embryogenesis, to reveal the exact course of 6 J.
