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.
Scales in 21 (23) rows, vertebral row enlarged; ventrals 209–239; anal entire; subcaudals... Wikipedia →

Possible
About 20% of wildlife watchers report a Gold-ringed Cat Snake sighting in Sepilok on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 34 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Gold-ringed Cat Snake in Sepilok on a given day, against under 5% in March, May, August and December–January, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Gold-ringed Cat Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Gold-ringed Cat Snake sightings, Sepilok ranks 3rd at about 20%. The best odds are in Kinabalu Park (Malaysia, about 30%) and Kinabatangan Wildlife Sanctuary (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the Gold-ringed Cat Snake is recorded against all the reptiles logged in Sepilok (16 verified sightings from 2019 to 2026), 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.
