Fluvidona griffithsi is a species of small freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Tateidae.

[1] Fluvidona griffithsi is named after Owen Lee Griffiths, who found the first specimens of this species.

This species is, with the possible exception of a single specimen found north of Kyogle, as of yet unidentified and most probably belonging to a distinct species, unique amongst known Australian hydrobiids in being able to aestivate and withstand drying.

The type series were found in dry soil in a small, dry creek bed on the landward side of a small hill, in a small coastal rainforest remnant in Burleigh Head National Park, Queensland.

Several days after collection they were placed in water, after which they soon emerged and crawled about actively.
