Colugos, belonging to the family Cynocephalidae, are extraordinary gliding mammals that possess the most extensive patagium among vertebrates, enabling them to glide impressively between trees. Often called "flying lemurs"—although they are neither true fliers nor lemurs—colugos are classified within the order Dermoptera, highlighting their unique evolutionary status. Their closest living relatives are the primates, reflecting deep evolutionary connections in their anatomy and genetics. Native to Southeast Asia, colugos exhibit remarkable adaptations for an arboreal lifestyle, including sharp claws, a robust grip, and specialized dentition for a herbivorous diet.

The patagium in colugos functions as a gliding membrane, allowing them to move efficiently between trees.
Colugos belong to the order *Dermoptera*.
Colugos are popularly called 'flying lemurs,' despite not being true lemurs or flyers.
Colugos are native to Southeast Asia.
Colugos share similarities in dental structure and other ancestral traits with primates, linking them evolutionarily.
Overview of Cynocephalidae
Colugos are the sole members of the family Cynocephalidae and are remarkable for their highly specialized gliding adaptations. Their patagium extends from the neck to the tips of the fingers, toes, and tail, allowing them to glide over distances of up to 70 meters. This adaptation minimizes energy expenditure and predation risk during arboreal travel.
- Family: Cynocephalidae
- Order: Dermoptera
- Main adaptation: Extensive gliding membrane (patagium)
Colugos are native to Southeast Asia.
Colugos are dermopterans, not flying squirrels or true lemurs.
Species of Colugos
There are only two extant species of colugos:
| Species | Common Name | Distribution |
|---|---|---|
| Cynocephalus volans | Philippine Colugo | Philippines |
| Galeopterus variegatus | Sunda Colugo | Mainland Southeast Asia |
- Both species show minimal differences in morphology but are separated by genetic and geographic factors.
- They are among the most efficient gliders in the animal kingdom.
There are two extant species of colugos.
Colugos have an extensive gliding membrane, sharp claws, and a herbivorous diet.
Colugos are primarily herbivorous, feeding on leaves, flowers, and sap.
Evolutionary Significance
Colugos provide critical insight into mammalian evolution, particularly the origins of primates. Their dental formula and aspects of their ear and skull morphology resemble those of early primates, supporting the idea that Dermoptera and Primates share a common ancestor.
- Closest living relatives: Primates
- Fossil record: Dates back to the Eocene epoch (~50 million years ago)
- Role in evolutionary studies: Shed light on primate origins and mammalian diversification
Colugos belong to the order Dermoptera.
Colugos are dermopterans with a remarkable gliding membrane and close ties to primates.
Colugos are native to tropical forests of Southeast Asia.
There are two recognized living species of colugos.
Colugos use an extensive patagium to glide efficiently between trees.
Conclusion
Colugos of the family Cynocephalidae are extraordinary gliding mammals whose adaptations and evolutionary history provide valuable insight into mammalian and primate evolution. Their unique morphology sets them apart as some of the most specialized arboreal mammals.
- Belong to the order Dermoptera and are closely related to primates.
- Possess the most extensive gliding membrane among mammals.
- Limited to two species found in Southeast Asia.
