Conclusion: Aplysia cf. nigrocincta
Reviewed by Codex identification research on Aug 27, 2026 · 84% reviewer confidence.
Reasoning recorded at review
- Small Aplysia with narrow folded parapodia fused posteriorly
- Brown body densely marked with pale spots
- Pale blue-white parapodial and cephalic-appendage margins
- Large oval mantle foramen is visible and not reduced to a small raised papilla
Alternatives considered
- Aplysia atromarginata or another former A. parvula-complex lineage
Why plausible: The 2019 revision split the old circumtropical A. parvula concept into ten taxa, several in the Indo-Pacific
Comparison: Mantle-aperture structure, shell, reproductive anatomy and DNA are needed to eliminate the closest lineages conclusively
Evidence limits & sources +−
- • No shell, internal anatomy or DNA
- • External colour is variable within the complex
