Abstract

A death assemblage of molluscs that had washed upon St. Kilda Beach in Melbourne, Australia was sampled by beachcombing the strandline in 2012. A total of 20 species consisting of ten bivalves and ten gastropods were identified. Faunal analysis revealed that 75% of the specimens were rocky and sandy species, and the remaining 25% were muddy-sand and muddy species. From the viewpoint of habitat preference, exposed shore species were generally more abundant than sheltered shore species, suggesting that the observed species composition resulted from variations in coastal geomorphology.
