Place the record in context.
Wallacea’s deep-water geography helps explain why an archipelago-wide label is too coarse for a species account. This navigation group also includes Aru; it is an editorial geographic grouping, not a single biogeographic unit.
This describes the wider region. Local vegetation and the habitat of an individual species require their own evidence.
The wider region
Maluku
Maluku and North Maluku, including the Aru Islands for this geographic index.

Landscape context

These guides describe documented environments in the wider Maluku region. They do not assign every listed species to every habitat or protected site.

Behind the occurrence.
Choose an account recorded in Halmahera. Its country-level evidence retains the named islands and qualifications; it is not a record of a sighting at an exact map point.
The shared collection
Snakes recorded here.
Each card opens the same species account used by the country lists. A shared island record does not imply occurrence in all countries sharing that island.
