The collared reed snake (Calamaria pavimentata) is a species of colubrid snake found in Asia. In Japan, it is also called Miyara's collared snake. The rostral is as deep as it is broad, and it is well visible from above. The frontal is longer than broad, shorter than the parietals, and 2.0 to 2.5 times as broad as the supraocular. C. pavimentata has one preocular scale and one postocular scale with four upper labials (the second and fourth are the largest, with the second and third entering the eye). The first pair of lower labials form a suture behind the mental scale. There are two pairs of chin shields, each pair in contact with the other. The scales are in 13 rows. There are 140–182 ventral scales, the anal scale is entire, and it has 13–27 subcaudal scales, and a pointed tail.
The collared reed snake is reddish-brown above, with five dark longitudinal lines or series of spots. The nape is dark brown and separated from the back by a yellow collar. A pair of yellow spots is seen at the base and another at the end of the tail. The lower parts show a uniform yellow with a dark line along the tail in the Burmese and Javan specimens, obscured with brown mottlings or... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Collared Reed Snake is recorded against all the reptiles logged in Khao Sok National Park (8 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.
