Gold-ringed Cat Snake

The mangrove snake, or gold-ringed cat snake, is a rear-fanged venomous snake in the family Colubridae, endemic to Southeast Asia. It is one of the biggest cat snake species, averaging 8–9 feet (2.4–2.7 m) in length. It is considered mildly venomous. Although moderate envenomations with intense swelling have been reported, the account used here notes no confirmed fatalities (Wikipedia, general species account).
