About the Tudors’s Coffee-Snake
The Tudors’s Coffee-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, Ninia, covers coffee snakes. Small, secretive forest-floor colubrids of Central and South America that hunt slugs and earthworms and pose no danger to people.
The Tudors’s Coffee-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.
