Species identification through karyotyping of wild planarians. Clearly distinct karyograms were obtained from three groups of morphologically similar planarians obtained in the wild. a A mixed population of planarians collected in Sardinia (Italy). b Wild planarians grouped based upon their gross morphology. c Karyotype belonging to planarians in the second morphological group. This karyotype is the same as the S. mediterranea karyotype. d Karyotype for planarians belonging to the first morphological group, which is Schmidtea polychroa. e Karyogram of the planarians belonging to the second and first morphological groups, which are diploid and triploid organisms, respectively
