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 →

GBIF citizen-science records
It is estimated from how often the Blunthead Slug Snake is recorded against all the reptiles logged in Danum Valley Conservation Area (6 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.
