Juvenile Whelk Microbiome Variation Across Dietary Transition Stages

A dataset from figshare characterizes the associated microbiota of the commercial marine gastropod Hemifusus tuba across three dietary stages. Yongli Wu authored this dataset, which contains 457,412 high-quality 16S rRNA reads clustered into 12,091 OTUs, identifying 811 genera within 38 phyla. The data was last updated on 2026-05-28.

Use Cases

• Analyzing taxonomic composition shifts based on the five dominant phyla (Proteobacteria, Bacteroidota, Firmicutes, Actinobacteriota, Planctomycetota) mentioned in the description.
• Studying alpha and beta diversity changes based on the reported transition from lecithotrophy to carnivory.
• Identifying microbial biomarkers for dietary stages based on the LEfSe-identified orders/families (Hyphomicrobiales/Bradyrhizobiaceae, Burkholderiales/Betaproteobacteria, Rhodobacterales/Roseobacteraceae).
• Predicting functional metabolic pathways based on PICRUSt2 predictions for tryptophan metabolism, methane metabolism, and the TCA cycle.
• Investigating potential microbial candidates for feed optimization in H. tuba domestication as suggested by the description.

Strengths

• Contains 457,412 high-quality 16S rRNA sequencing reads.
• Identifies 12,091 OTUs spanning 811 genera and 38 phyla.
• Compares microbiome data across three distinct dietary stages (CK, He, Ca).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 11.2 KB, indicating limited scope.
