Fluvidona anodonta, more commonly known as the North Pine River freshwater snail, is a species of small 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.

Fluvidona anodonta's habitat has multiple human imposed threats including habitat fragmentation, road water runoff unbalancing the natural ecosystem and horses disturbing the underwater ecosystem. In 2011 the International Union for Conservation of Nature listed Fluvidona anodonta as a vulnerable species. There are currently no species specific conservation measures, however general recommendations for the protection of organisms living in similar environments have been made. These include habitat monitoring for increased pollution levels as well as surveying the current distribution and populations of the snail.
