Frilled Lizard (Chlamydosaurus kingii) Frilled Lizard or Frill-Necked Lizard is a large lizard species belonging to the Agamidae family. They are native to various regions of Australia and New Guinea. Though they are found only in the dry woodlands of Australia and New Guinea, they are quite popular around the world for their unique defence strategy. The frill like ruff around the neck of this lizard earned it the name Frill-Necked Lizard. Description The frilled lizard, also known as the frilled neck lizard, frilled dragon or dragon lizard, is a unique reptile, popular for its frill around the neck. The creators of Jurassic Park were inspired by the Frilled Lizard when they designed their version of Dilophosaurus, the spitting dinosaur. Frilled lizards, or "frillnecks," are members of the dragon family that live in the tropical and warm temperate forests and savanna woodlands of northern Australia. But we don't know if Dilophosaurus had a frill, and the Frilled Lizard doesn't have venom, much less spit it.
