| Abstract |
Intersexuality in the mysid Neomysis integer is described from samples collected in the Elbe (north Germany), Eems-Dollard (north Netherlands), Westerschelde (south-west Netherlands) and Gironde (south-west France) estuaries. Individuals which had an irregularly shaped or nearly symmetrically rounded telson, rather than a typically truncated one, were also recorded from the four populations studied. A culture experiment with damaged specimens revealed that all types of abnormal telson morphology found in the field can result from regeneration of damaged parts. It is concluded that both intersexuality and aberrant telson morphology are widespread phenomena among estuarine N. integer populations. Both abnormalities seem to be rare in the other common mysid species in the study area: only one intersexual Gastrosaccus spinifer and one Schistomysis kervillei with an aberrant telson were recorded. |
