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 20% of wildlife watchers report a Keeled Slug Snake sighting in Kaeng Krachan National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 56 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.
November and December
In those months about 30% of wildlife watchers report a Keeled Slug Snake in Kaeng Krachan National Park on a given day, against under 5% in April and August–September, the lowest months. Those are among Kaeng Krachan National Park's driest months, with about 65 mm of rain a month against 260 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.
3rd of 4
Of the 4 parks where we can rate Keeled Slug Snake sightings, Kaeng Krachan National Park ranks 3rd at about 20%. The best odds are in Cat Tien National Park (Vietnam, about 30%) and Gunung Leuser National Park (Indonesia, about 30%).
GBIF citizen-science records
It is estimated from how often the Keeled Slug Snake is recorded against all the reptiles logged in Kaeng Krachan National Park (24 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.
