Monitors like the perentie have a forked tongue which they flick out to collect scent particles. Scents are interpreted using a structure on the roof of the mouth called the Jacobson’s organ.
The sandy colours of the perenties scales help them camoflauge in the arid deserts where they are found.
To see this species in the wild, we suggest Barrow Lisland, Western Australia.
