Dendrelaphis caudolineatus, commonly known as the striped bronzeback or grey bronzeback, is a species of colubrid snake found in Southeast Asia.

However, in Latin "cauda" means tail and "linea" mean line, possibly referencing the longitudinal lines reaching from head to tail.
Dendrelaphis caudolineatus belongs to the genus Dendrelaphis, which contains 48 other described species. Prior to a 2012 study, several other species of Dendrelaphis were previously considered to be members of Dendrelaphis caudolineatus, but are now considered to be separate species: D. flavescens, D. terrificus, D. philippinensis, and D. levitoni.
Dendrelaphis is one of five genera belonging to the vine snake subfamily Ahaetuliinae, of which Dendrelaphis is most closely related to Chrysopelea, as shown in the cladogram below: Dendrelaphis caudolineatus is found in Malaysia, Thailand, Indonesia, Brunei, and Singapore. It is found in a wide variety of forested habitats, commonly seen in trees and bushes, most... Wikipedia →

Possible
About 30% of wildlife watchers report a Gray Bronzeback sighting in Sepilok on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 34 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.

GBIF citizen-science records
It is estimated from how often the Gray Bronzeback is recorded against all the reptiles logged in Sepilok (33 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.
