Aplopeltura is a genus of snakes of the family Pareidae. It contains a single species, Aplopeltura boa, the blunthead slug snake or blunt-headed slug-eating snake. It is a small, non-venomous snake. The species can be found in southern Thailand, Malaysia, Indonesia, Brunei and the Philippines.
A. boa eats mainly snails, especially operculate species. Their jaws are more mobile than those of most other vertebrates. With their mandibles, they cut the operculum off from their prey with a unique "sawing" motion. A. boa has been observed performing simple death feigning behavior. The snake rolls itself into a spiral with its belly up, staying still until the threat leaves. Unlike other death feigning snakes, A. boa does not emit a foul odor or open its mouth. Wikipedia →

Possible
About 30% of wildlife watchers report a Blunthead Slug Snake sighting in Kinabalu Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 69 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February and July–December
In those months about 40% of wildlife watchers report a Blunthead Slug Snake in Kinabalu Park on a given day, against about 20% in January and March–May, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Blunthead Slug 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.
Yes
Of the 2 parks where we can rate Blunthead Slug Snake sightings, Kinabalu Park has the highest daily chance: about 30%. Next come Danum Valley Conservation Area (Malaysia, about 10%).
Same family: Pareidae
The closest relatives of the Blunthead Slug Snake that you can see in Kinabalu Park (family Pareidae, Slug Snakes) are Inger’s Slug Snake (about 30%), Bornean dark-necked slug snake (about 20%) and Smooth Slug Snake (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blunthead Slug Snake is recorded against all the reptiles logged in Kinabalu Park (42 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.
