Lace Monitor (Goanna)
Sounds

The Lace Monitor (Varanus varius) is a large species of monitor lizard (goanna) found in eastern Australia. They inhabit rainforests, eucalypt forests and woodlands, and spend much of their time in trees. 

What does a Lace Monitor sound like? Lace Monitors can make drawn-out, breathy hissing sounds when they feel threatened. These sounds are made by inflating the throat, and are often accompanied by a defensive posture making the animal appear larger. In addition to these noises, Lace Monitors can flick their tail like a whip to defend themselves from a predator (or human that comes too close!).
