Morphological Data for Cave-Dwelling Catfish in Colombia

Data from the project 'Shaping in the Dark: Recurrent Body Shape Patterns in Cave- and Surface-Dwelling Trichomycterid Catfishes' by Nelson Falcón-Espitia. The 3.4 MB dataset, last updated in April 2026, supports analysis of body shape evolution in Colombian catfish lineages in relation to their ecological context. The data is provided in TXT format under a CC-BY-4.0 license.

Use Cases

• Analyzing convergent body shape evolution based on comparisons between cave- and surface-dwelling lineages mentioned in the description.
• Studying morphological adaptation based on the functional context derived from ecological data described in the project.
• Conducting phylogenetic comparative analyses based on body shape patterns across different catfish lineages in Colombia.

Strengths

• Data is peer-reviewed, with a version (R1) adjusted after the first round of review.
• Clear project context and research objective are provided in the description.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 3.4 MB size suggests a small dataset, potentially limiting statistical power.
