Crown of Thorns Seastar Larval Development Under Food and Light Treatments

Experimental data from 2022 to 2025 on the development, survival, and settlement of Crown of thorns seastar (Acanthaster cf. solaris) larvae. Larvae were cultured under controlled laboratory conditions at the Australian Institute of Marine Science National Sea Simulator, with manipulated food and light treatments. Larval morphology, mortality, and settlement success were assessed at multiple developmental stages and analyzed using generalised linear mixed effects models.

Use Cases

• Modeling larval survival rates based on food availability and light conditions described in the experiment.
• Analyzing morphological development progression from early bipinnaria to late brachiolaria stages.
• Predicting settlement success using data from assays with crustose coralline algae chips.
• Investigating the effects of algal diet mixtures (Dunaliella sp. and Tisochrysis lutea) on larval growth.

Strengths

• Data collected under controlled laboratory conditions at a major marine research facility (AIMS National Sea Simulator).
• Experiments span a multi-year period from 2022 to 2025.
• Multiple response variables were measured, including larval development stage, morphology, mortality, and settlement success.

Limitations

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