The Dreissenidae are a family of small freshwater mussels, aquatic bivalve molluscs. They attach themselves to stones or to any other hard surface using a byssus. The shells of these bivalves are shaped somewhat like those of true mussels, and they also attach themselves to a hard substrate using a byssus, however this group is not at all closely related to true mussels, being more closely related to the venus clams (Veneridae).
The Unionidae are a family of freshwater mussels, the largest in the order Unionida, the bivalve molluscs sometimes known as river mussels, or simply as unionids.

Fluvidona anodonta or more commonly known as the North Pine River freshwater snail is a species of minute freshwater snail that is endemic to Australia. Originally discovered in 1892 by Hedley & Musson, the snail is highly elusive and only has been sighted four times since its discovery. The snail is 2 mm long and 1 mm wide with the shell colouring being of a yellow-whiteish shade. Fluvidona anodonta resides within the City of Moreton Bay, specifically in four river systems within the D'Aguilar National Park, Queensland. The four river systems are the South Pine River headwaters, the North Pine River headwaters, Kobble Creek and Low Branch Creek. The snail is found under deeply submerged rocks within permanent freshwater systems.
