摘要: Abstract Osmoregulation is a key regulatory function in animals inhabiting brackish waters or areas subject to considerable salinity change, such as estuaries. While our understanding of osmoregulation adult crustaceans relatively good, knowledge how osmoregulatory ability develops during ontogeny not well documented. In indirect developers, improvement capacity appears coincide with major metamorphosis. This consistent the ‘incomplete hypothesis’, which assumes that early developmental stages are individuals’ operating less efficiently than individuals at older stages. Evidence for this clear direct developers. Consequently, we tested by characterising euryhaline amphipod, Gammarus chevreuxi, species undergoes development. We investigated structure and putative tissues, together regulation genes. Embryos were examined stages: before dorsal organ (DO), structure, appeared (
