Medauroidea extradentata, commonly known as the Vietnamese or Annam walking stick, is a species of the family Phasmatidae.

Their chewing mouthparts are specially adapted for eating plant material, opening horizontally instead of vertically.

Like some species of lizards, their legs can fall off due to stress, if being held (by a predator or an object) or when molting.

[1] Medauroidea extradentata is mainly parthenogenetic, meaning they are asexual, making males very rare in the species.

Their main predators are birds and small mammals, though their camouflage helps them combat this.
