Ichetucknee siltsnail
species of Gastropoda
The Ichetucknee siltsnail, also known as the sand grain snail, scientific name Floridobia mica, is a species of small freshwater snail, an aquatic gastropod in the family Hydrobiidae.
This species is characterized by its association with bryophytes and eelgrass, with females typically being larger than males. The snails show sexual dimorphism, and their population includes both adult and juvenile individuals, indicating active recruitment. The majority of specimens are juveniles, identified by having one to one and one-half whorls.
Distribution
This species is endemic to Ichetucknee Springs in Florida. The snail is confined to an extremely small geographic area, with its extent of occurrence limited to the surface area of Coffee Spring, which ranges between 18.8 and 364 square meters depending on water levels. Coffee Spring provides a stable environment with uniform temperature and flow conditions, critical for the snail's survival.
Ecology
This siltsnail primarily inhabits bryophyte-covered limestone bedrock and eelgrass habitats within Coffee Spring. It grazes on periphyton and detritus and can tolerate low dissolved oxygen levels, which protect it from most fish predators. The snail's life history and environmental requirements remain largely understudied, but it is known to have a one-year lifespan with continuous recruitment in warm spring systems.
The public source identifies “Ichetucknee siltsnail” as species of Gastropoda. This brief keeps that definition visible, then builds a research path around Ichetucknee, siltsnail and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Ichetucknee siltsnail”, the useful work is to connect “species of Gastropoda” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 12, 2026. The linked authority identifier is Q28296246. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
