It has very enlarged cheek scales, a prominent crest, and a yellow dewlap under its chin. Adults are sexually dimorphic, with males larger than females and having larger, blockier heads. It spends the majority of its time perched on the trunks of trees, usually at around head height, although daily movements can exceed 100 metres. When approached, it will usually move around to the opposite side of the tree, keeping the trunk between it and its harasser. It doesn't bask, instead letting its body temperature fluctuate with air temperature. The one possible exception to this general rule is gravid females, which are often observed sitting beside roads and exhibit elevated body temperatures. Lizards commence activity at dawn and cease activity at dusk, remaining active even when it rains. Act
