Boyd's forest dragons are generally brown or grey above, with some individuals having a green flush. The body is laterally compressed. They have very enlarged cheek scales, a prominent nuchal crest, and a yellow dewlap under the chin that is edged with enlarged spines. The males are larger than females and have larger, blockier heads
The species is restricted to rainforests and their margins in northern Queensland, Australia, from just north of Townsville to near Cooktown.
Their diet consists primarily of invertebrates, with earthworms making up a relatively high proportion. Small fruits and vertebrates are also occasionally consumed.
The Boyd’s Forest Dragons begin their breeding in the wet season. Just one to six eggs are produced in each clutch, they are laid in small nests on the forest floor, and will take about three months to incubate.
