To assess the influence of its discontinuous geographic distribution on morphometric variability between isolated populations, we conducted a biometric study of S. setosa from three different locations: Goteborg and Plymouth (North Atlantic) and Barcelona ( Western Mediterranean). Out results do indicate some disparity between the populations that is reflected not in size differences, largely determined by water temperature, but in shape (body proportions).5 p.application/pdfengcc-by-nc (c) Consejo Superior de Investigaciones Científicas (CSIC), 1990http://creativecommons.org/licenses/by-nc/3.0/esQuetògnatsBiometriaChaetognathaBiometryinfo:eu-repo/semantics/article1961752012-10-30info:eu-repo/semantics/openAccess
