folk medicine. However, the Hong Kong Reptile and Amphibian Society has found that this species is sold in pet shops in Hong Kong, with the specimens almost certainly locally caught, even though the species is locally protected. It is also threatened by habitat loss. The fact that it lays only one clutch per year and that the eggs are often heavily infested with
ants makes conservation efforts even harder for this already very rare species.
