Calamaria griswoldi, also known commonly as the dwarf reed snake and the lined reed snake, is a species of snake in the subfamily Calamariinae of the family Colubridae. The species is native to Borneo. The specific name, griswoldi, is in honor of American ornithologist John Augustus Griswold Jr. (1912–1991), who collected the holotype.
Calamaria griswoldi is endemic to Borneo with records from Sabah and Sarawak (Malaysia). The preferred natural habitat of Calamaria griswoldi is forest, at elevations of 1,000–1,500 m (3,300–4,900 ft). Calamaria griswoldi is a small species. Maximum recorded total length (tail included) is 49 cm (19 in).

Possible
About 30% of wildlife watchers report a Lined Reed Snake sighting in Kinabalu Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 69 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.
February, July and December
In those months about 40% of wildlife watchers report a Lined Reed Snake in Kinabalu Park on a given day, against under 5% in September, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Lined Reed 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.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Lined Reed Snake sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Calamaria
The closest relatives of the Lined Reed Snake that you can see in Kinabalu Park (genus Calamaria) are Schmidt's Reed Snake (about 40%) and Samarinda Reed Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lined Reed Snake is recorded against all the reptiles logged in Kinabalu Park (31 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.
