Global DNA Barcode Reference Library for Solenogastres Molluscs

A global collection of DNA barcode sequences for Solenogastres, a group of shell-less marine molluscs. The dataset comprises 655 newly generated sequences combined with previously published data, resulting in 531 COI, 483 16S, and 129 CytB barcodes from 642 specimens representing an estimated 325 species. It was created by Emily L. McLaughlin and last updated in May 2026.

Use Cases

• Species identification and discovery based on DNA barcode sequences.
• Phylogenetic analysis to resolve taxonomic relationships within Solenogastres.
• Assessing marine biodiversity and geographic distribution patterns of aplacophoran molluscs.
• Training or benchmarking DNA barcode reference databases for marine invertebrate taxonomy.

Strengths

• Integrates 655 new sequences with existing data for a total of 1143 barcodes across three genetic markers.
• Covers an estimated 325 species from 642 specimens, representing broad taxonomic and geographic diversity.
• Specimen identification uses an integrative approach combining molecular data with detailed morphological information from histology and microscopy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 27.5 KB file size suggests a small, metadata-focused dataset rather than a large sequence repository.
