Frill-necked lizard
These lizards spend most of their life in trees (they are primarily arboreal). They live in the north of Australia and in New Guinea. They inhabit moist tropical and warm-temperate forests and in woodlands with shrubby understory. When displayed, the frill is 9.5-14 inches (24-34 cm) wide. When the lizard is at rest, the frill folds down on its shoulders. Adults are over 8 inches (20 cm) long.
