When laying eggs, the Frilled Lizard female makes a hole and lays the eggs in the hole, and covers them up. It takes about 3 months for the eggs to hatch. They have frills as soon as they hatch. If threatened, it opens it’s mouth and hisses. If that fails it starts to run to the closest tree. It has good camouflage to the tree trunks. They are usually black or brown.
