In this article, I would like to write about the flying dragon, a fascinating type of reptile. No, not the mythical dragon from fantasy stories, but a real reptile found in Singapore that has wing-like membranes allowing it to glide gracefully from tree to tree.
The reptile I am referring to is commonly known as the flying dragon, a member of the genus Draco. These small lizards usually measure between 22 cm and 24 cm in length, including their long slender tails. What makes them particularly remarkable is the set of rib-supported membranes along their sides, which they can extend like wings. When spread out, these membranes allow the lizard to glide through the air from one tree to another, helping it move efficiently through the forest without needing to descend to the ground.
During one of my outings, I managed to spot one resting quietly on the bark of a tree. Its body coloration blended extremely well with the texture of the trunk, making it difficult to notice at first glance. I was fortunate enough to capture a photograph of it from a distance. Unfortunately, I was unable to capture the moment when it expanded its wings to glide, which would have been an incredible sight. Nevertheless, observing this unique reptile in its natural environment was already a memorable experience.
There are three types of fly dragon known locally.
Draco sumatranus, commonly known as the Common Flying Dragon (Photo shown above), is the species most frequently encountered in Singapore.
- Often seen resting on tree trunks at eye level.
- Found in forests, parks, and even some urban green spaces.
- Excellent camouflage allows it to blend into tree bark.
- Uses rib-supported membranes (patagia) to glide between trees.
Draco quinquefasciatus, the Five-banded Flying Lizard, is much rarer locally.
- Reported mainly in Central Catchment Nature Reserve (CCNR).
- Very difficult to spot due to low population and forest canopy habitat.
- Listed locally as endangered.
- Named after the distinct banding pattern on its gliding membrane.
Draco melanopogon, also called the Black-bearded Flying Dragon or Black-barbed Gliding Lizard, is another forest species.
- Generally found deep inside mature forests.
- Less vulnerable than D. quinquefasciatus but still not commonly seen.
- Recognizable by the dark “beard” (dewlap) under the throat.
Because of its preference for interior forest habitat, encounters are relatively uncommon.
The next time you do a nature walk, do see if you can spot any of it.
