Crown of Thorns Seastar Larval Development Under Food and Light Treatments

Australian Institute of Marine Science research from 2022 to 2025 on larval development of the Crown of thorns seastar (Acanthaster cf. solaris). The dataset contains measurements of larval morphology, mortality, and settlement success under manipulated food and light conditions in controlled laboratory experiments. Data were analyzed using generalised linear mixed effects models in R.

Use Cases

• Modeling larval survival rates based on food availability and light conditions.
• Analyzing morphological development progression from bipinnaria to brachiolaria stages.
• Studying the effects of algal food mixtures on settlement success.
• Investigating the impact of environmental variables on CoTS population outbreaks.

Strengths

• Data collected from controlled laboratory experiments at the AIMS National Sea Simulator facility.
• Larval development was quantified at multiple stages, including morphological measurements from microscopy images.
• Experiments were conducted over a multi-year period from 2022 to 2025.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect experimental bias inherent to controlled laboratory conditions.
