Photographic Observation of the Mangrove Slug Platevindex sp. Across Selected Sites in Klang Straits, Selangor

The mangrove slug Platevindex sp. is one of the most abundant non-shelled gastropods in the Straits of Malacca, yet it remains understudied, particularly in relation to habitat disturbance and pollution.This study provides the first photographic observational record of Platevindex sp. from several sites along the Klang Straits in Selangor.Field surveys were conducted from 4 October to 23 November 2025 to document the species' presence, microhabitat use, and visible pollution indicators within mangrove environments.Informal interviews with local residents were used to supplement field interpretations.Observations showed that in disturbed sites, slugs frequently occupied man-made substrates such as artificial rocks, discarded wood, and debris rather than natural structures such as pneumatophores.This apparent shift in microhabitat use suggests that habitat alteration and pollution pressures may be influencing behavioural responses.As this study represents an exploratory assessment, future systematic work is recommended to evaluate toxicological effects on the behaviour, habitat utilisation, and genetic diversity of Platevindex sp.public awareness on pollution in mangrove areas and potential ecological consequences is also needed.
