## Where were observations reported?

Place labels appearing in the results include West Java, Bali, Central Java. They are labels attached to records, not a complete range map or evidence that the species occurs only there. Some labels may be broad or inconsistent. Check the underlying records before using the location information for field decisions.

## How can you observe the Keeled Slug Snake?

A safe-distance photograph can record body, head and tail pattern and locality without handling the animal. Colour alone cannot establish whether a snake is venomous; seek local professional help if there is risk. A well-documented sighting helps others check the identification without turning one encounter into a conservation-status claim.
