About the Narrow-banded Rain Snake
The Narrow-banded Rain Snake belongs to the Colubridae family, colubrids. The largest snake family, and the one most snakes you meet belong to.
Colubridae is by far the biggest family of snakes, with roughly two thousand species worldwide. It is a catch-all of mostly slender, agile, day-active snakes: ratsnakes, kingsnakes, gartersnakes, watersnakes, racers, whipsnakes, and hundreds more. The vast majority are harmless to people and kill prey by grabbing or constricting rather than with venom.
Its genus, Smithophis, covers rain snakes. Smithophis is a small genus of stream-loving Asian colubrids known only from the wet hill country of northeast India and nearby Myanmar.
The Narrow-banded Rain Snake is non-venomous and harmless to people. Like most snakes it is a quiet predator that helps keep rodents and other small prey in check.
