In the Aeolian Archipelago (Tab. 2) 112 specimens, belonging to 35 species, were
found. In this archipelago on a total of 66 investigated stations only 24 had living
molluscs. Panarea was the island with the greatest diversity (18 species), followed by
Lipari and Salina (both with 7 species), Vulcano and Filicudi (both with 6 species) and
Stromboli (2 species). In this case, the soft bottoms were characterised by coarse
sediments with presence of volcanic sand until 45 m depth.

The bivalve Thyasira flexuosa reached a remarkable high density (~100 ind./m2)
in one spot around the Vulcano Island (station 38, 90m depth). This species is typically
found in muddy sediments with a high organic load and/or presence of sulfides where it
