Life History of Lithoredo Abatanica, a Freshwater Macrobioeroding Bivalve

Lithoredo abatanica is the largest known freshwater macrobioeroder, operating at a fundamentally different scale of rock breakdown. This dataset investigates its reproductive mode and life history strategy using population size structure, siphonal morphology, and sperm morphometrics. The study was authored by Reuben Shipway and last updated in May 2026.

Use Cases

• Modeling population persistence and dispersal of a broadcast-spawning species based on life history data.
• Analyzing the relationship between organismal size and excavation scale in freshwater bioeroders.
• Studying reproductive strategies in isolated riverine habitats based on sperm morphometrics and siphonal morphology.

Strengths

• Dataset is focused on Lithoredo abatanica, the largest known freshwater macrobioeroder by an order of magnitude.
• Analysis includes multiple data sources: population size structure, in situ siphonal observations, and sperm morphometrics.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Dataset size is only 17.0 KB, indicating a very limited scope.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
