New Zealand Journal of Marine and Freshwater Research abstractsDistribution of the spider crab, Leptomithrax longipes, and evidence of bacterially induced feminisationD. S. RoperPortobello Marine Laboratory, University of Olago, Dunedin, New ZealandAbstract The distribution of Leptomithrax longipes (Thomson), on the continental shelf east of the Otago Peninsula appears to be affected by females migrating into deeper water at the edge of the shelf. The presence of immature crabs inshore suggests the existence of an onshore current. Nine sexually indeterminate individuals were examined; their combination of male and female characters indicated that they were males undergoing a process of feminisation. Tissue and blood smears contained a bacterium which was possibly causing this feminisation.
