The keeled slug-eating snake (Pareas carinatus) is a species of snake in the family Pareidae. It is relatively widespread in Southeast Asia, from southern China (Yunnan) to Burma and Indochina to the Malay Archipelago (Borneo, Java, Lombok, Sumatra, Bali).
Keeled slug-eating snakes live in or near forests. They are nocturnal and mostly arboreal, and as the common name suggests, they feed exclusively on snails and slugs. They are oviparous. While the species is negatively affected by forest destruction, IUCN considers these effects to be localized and not threatening the species. Wikipedia →

Possible
About 30% of wildlife watchers report a Keeled Slug Snake sighting in Gunung Leuser National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 47 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Keeled Slug Snake in Gunung Leuser National Park on a given day, against under 5% in August and November–February, the lowest months. That is one of Gunung Leuser National Park's driest months, with about 180 mm of rain against 700 mm in September.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Keeled Slug Snake sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Keeled Slug Snake sightings, Gunung Leuser National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Cat Tien National Park (Vietnam, about 30%).
GBIF citizen-science records
It is estimated from how often the Keeled Slug Snake is recorded against all the reptiles logged in Gunung Leuser National Park (19 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.
