Similar Species: Jagor’s Water Snake is very similar in appearance, but is not found in the Mekong Delta. Scale counts may be necessary to tell them apart.

Interesting facts: This species is only found in the Mekong Delta, though due to taxonomic confusion it was previously thought to be more widespread.
