Boiga dendrophila melanota (Boie, 1827)

Species:B. dendrophila
Common Names:Gold-ringed Cat Snake


Measuring up to 2.5 m, this is the biggest and most distinctive of the cat snakes found here. They are black with yellow stripes that do not meet over the back, thus not actually forming a ring, as suggested in its common name. Their throat and anterior ventral are also bright yellow. The body is large, robust and laterally compressed, with the head being distinct from the neck.

General Biology

Nocturnal and will forage in the trees, dense undergrowth, on the ground and along riverbanks. When at rest, they are arboreal and can often be found coiled on branches near or overhanging water. They are often found in mangroves which is why it is also commonly known as the Mangrove Snake, but it also inhabits lowland forests and even enters lowland mixed dipterocarp forests. They are mildly venomous.


Feeds on birds and their eggs, amphibians, lizards, other snakes and even small mammals like shrews and mousedeers.

Life Cycle

Oviparous, they lay 4–15 large eggs per clutch and incubate them over a period of 86 days. Hatchlings resemble the adults and measure about 350–430 mm.
