Marine fauna of the Mljet National Park (Adriatic Sea, Croatia). 4. Mollusca: Polyplacophora

During the summers from 1995-2000 the benthos was studied at 63 sites by scuba- and skin-divers. Polyplacophora molluscs were recorded at 36 sites. Ten species were identified, i.e. 63 % of the Adriatic Sea chitons, and 34 % of taxa recorded in the Mediterranean. Synonyms, habitat, depth range and general distribution are noted for each species. With the aim of updating the distributional pattern of chitons in the Adriatic Sea, the authors' unpublished records of a number of species have been appended.
