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 under manipulated food and light conditions. The study was conducted at the Australian Institute of Marine Science National Sea Simulator facility using larvae from wild-collected adults. Larval progression, morphology, mortality, and settlement success were assessed at multiple stages using microscopy and settlement assays.

Use Cases

• Modeling larval survival rates based on food availability and light conditions.
• Analyzing morphological development stages from microscopy images.
• Studying the effects of environmental factors on settlement success using crustose coralline algae assays.

Strengths

• Data collected under controlled laboratory conditions at a major marine research facility (AIMS).
• Larval development was tracked through multiple stages from early bipinnaria to late brachiolaria.
• Analysis performed using generalized linear mixed effects models with R software v4.2.2.

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 temporal and methodological bias inherent to the specific experimental setup.
