Conclusion: Pleurobranchus forskalii
Reviewed by Codex identification research on Aug 27, 2026 · 95% reviewer confidence.
Reasoning recorded at review
- Large oval side-gilled slug with a tuberculate mantle
- Mature dark reddish-purple colour form
- Broad compound dorsal tubercles
- Conspicuous opaque pale arcs outline the compound tubercle groups
Alternatives considered
- Pleurobranchus peronii
Why plausible: The dark-purple forms of P. forskalii and P. peronii can be difficult to distinguish in the field
Comparison: P. peronii is expected to show darker pigment rings on some polygonal tubercles and contrasting rhinophore tips, rather than the conspicuous pale arcs visible here
