Draco melanopogon, commonly known as the black-bearded gliding lizard or black-barbed flying dragon, is a species of agamid "flying lizard" endemic to Southeast Asia. It is a typically forest-dwelling arboreal lizard. It preys on small invertebrates like ants and is oviparous. They are notable for relying solely on dewlap-mediated communication, instead of conveying signals via both headbobbing and employing dewlaps, as is typical for lizards with dewlaps.
