419,177 SNP Candidates in Japanese and Chinese Giant Salamanders

Takeshi Igawa published a dataset of 419,177 single nucleotide polymorphism (SNP) candidates identified among Japanese giant salamanders, Chinese giant salamanders, and hybrid individuals. The data is relative to a reference Chinese giant salamander genome and was last updated on June 1, 2026. The dataset is provided as a 129.8 MB XLSX file under a CC-BY-4.0 license.

Use Cases

• Identify genetic markers for species differentiation based on SNP data.
• Study hybridization patterns between Japanese and Chinese giant salamanders.
• Conduct population structure analysis using the large set of SNP candidates.
• Perform genome-wide association studies (GWAS) for traits in giant salamanders.

Strengths

• Contains 419,177 SNP candidates, providing a substantial genetic marker resource.
• Data is explicitly identified for three groups: two species and their hybrids.
• Dataset is openly available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analyses.
• Description metadata is limited; actual data quality requires manual inspection after download.
