Behind the occurrence.
Choose an account recorded in Riau Islands. 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.
