A dataset and analysis script quantifying escape response kinematics and timing in Spotted Ratfish (Hydrolagus colliei). The data, created by Vincent Mélançon and last updated in April 2026, likely contains measurements of turning rates and response latencies elicited by a mechano-acoustic stimulus. The findings suggest ratfish performance is intermediate between other chondrichthyans and teleosts.
Use Cases
- Analyze differences in escape response latency between fish groups based on the described comparison of ratfish, elasmobranchs, and teleosts.
- Model the relationship between Mauthner cell presence and turning rate performance based on the described kinematic features.
- Compare predator evasion strategies across vertebrate lineages based on the described behavioral mechanism.
- Assess the vulnerability of chondrichthyan species to predation based on the described escape performance metrics.
Strengths
- Includes a statistical analysis script (RMD format) for reproducibility.
- Dataset is small (1.3 MB), facilitating quick download and inspection.
- 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
