Predominantly found in primary and mature secondary lowland rainforests, the slender Blue Bronzeback (Dendrelaphis cyanochloris) is arboreal. This non-venomous snake is diurnal and is native to Singapore, distributed from India to Thailand, and the Malay Peninsula. They usually eat lizards and frogs and have been observed hunting on the forest floor for lizards.
This species is most easily identified when it puffs up as a form of defence. At such times, the vivid blue is revealed.

It is unclear if Blue Bronzebacks are territorial as they do not have a clear territory that they patrol and defend. Rather, they defend themselves against potential predators. As for its sociality, observations indicate a solitary life. Blue Bronzeback snakes can be found in Bukit Timah Nature Reserve and Central Catchment Nature Reserve.
