Brittle Star Regeneration Histology and Measurements Under Cadmium Exposure

Persian Gulf brittle stars (Ophiocoma scolopendrina) are studied in this dataset, which includes high-resolution histological micrographs and arm length measurements from specimens exposed to cadmium. The data was collected by Nasim Nowruzi and supports a 2025 manuscript for the Journal of the Marine Biological Association of the United Kingdom. It contains raw data for 21 specimens per group across seven time points up to 42 days post-amputation.

Use Cases

• Quantifying regeneration rate delays based on arm length measurement datasets
• Analyzing wound healing and tissue morphology based on high-resolution histological micrographs
• Studying skeletal fragility and biomineralization interference using supplementary mechanical testing video
• Investigating resource reallocation in regeneration based on podia development observations mentioned in the description

Strengths

• Includes raw data for 21 specimens per experimental group (control and cadmium-exposed)
• Covers seven specific time points post-amputation (24h, 72h, 7d, 14d, 21d, 35d, 42d)
• Uses a defined cadmium exposure concentration of 50 µg/l CdCl₂
• Dataset size is 132.9 MB, indicating substantial raw image and video content

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for measurement data is unknown, which may limit suitability assessment
