Boiga dendrophila, commonly called the mangrove snake or the gold-ringed cat snake, is a species of rear-fanged venomous snake in the family Colubridae. The species is 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 resulting in intense swelling have been reported, there has never been a confirmed fatality.
B. dendrophila has the following characteristics: Snout longer than eye; rostral broader than deep, visible from above; internasals as long as or shorter than the prae-frontals; frontal as long as or slightly shorter than its distance from the tip of the snout; loreal at least as long as deep; a praeocular extending to the upper surface of the head, not reaching the frontal; two postoculars; temporals 2 + 2 or 2 + 3; eight (nine) upper labials, third to fifth entering the eye; four or five lower labials in contact with the anterior chin-shields; latter as long as or longer than the posterior; anterior palatine teeth not much larger than the posterior.

GBIF citizen-science records
It is estimated from how often the Gold-ringed Cat Snake is recorded against all the reptiles logged in Denpasar (27 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
