Known variously as Peters’ Forest Dragon, Doria’s 
Anglehead Lizard, or Abbott’s Anglehead Lizard (depending 
on subspecies), Gonocephalus doriae is known from southern 
Thailand, western Malaysia, and Indonesia west of Wallace’s Line 
(a biogeographic division between islands associated with Asia and 
those with plants and animals more closely related to those on Australia).
They live in remaining forested areas to elevations of 1,600 m (4,800 ft),
where they spend most of their time high in trees near streams, either
clinging to vertical trunks or sitting on the ends of thin branches. Their
conservation status has not been assessed.
