We carried out a comparison between the results of several clustering procedures and the zoocoenoses defined by A. Vatova after his studies on the Adriatic macrozoobenthos (1934–36). The original data set was analysed by means of hierarchical and non-hierarchical clustering algorithms, with and without contiguity constraint, as well as with different combinations of distance/dissimilarity indexes and data normalization. None of the partitions obtained from these procedures matched satisfactorily the original classification, which had probably been based on information that is not available in the numerical abundance data reported by the Author. Therefore, we recommend that only binary information from this data set should be taken into account for further analyses involving recent data sets.
