Conclusion: Pleurobranchus cf. forskalii
Reviewed by Codex identification research on Aug 27, 2026 · 88% reviewer confidence.
Reasoning recorded at review
- Large oval side-gilled slug with the right-side bipinnate gill visible
- Dark reddish-purple mature colour form
- Broad compound and ridged dorsal tubercles
- Rhinophores and oral veil match the mantle colour
Alternatives considered
- Pleurobranchus peronii
Why plausible: A dark-purple P. peronii can resemble P. forskalii and this frame lacks the latter's strongest pale-arc pattern
Comparison: A dorsal view resolving rings on individual polygonal tubercles and rhinophore-tip colour would separate the field characters more securely
- Pleurobranchus hilli
Why plausible: The iNaturalist model proposed this name at low confidence
Comparison: The revision restricts P. hilli to temperate south-eastern Australia and diagnoses very large warty irregular tubercles; neither the Tawali locality nor this mantle matches that account
Evidence limits & sources +−
- • Pale dorsal arcs are not clearly visible in this view
