Interesting fact!
Monitors are the only lizards that have a deeply forked tongue like that of a snake. There is a Jacobson’s organ on the roof of the mouth, also like that of snakes. The tongue constantly flicks in and out, transferring information to the Jacobson’s organ. This sensitive chemoreceptor can detect minute traces of odours in the air, whether from a prey item, a predator, or a potential mate. Because the tongue is forked, the lizard can receive information from both sides of its head, and figure out what direction the odours are coming from.

The lace monitor or tree goanna is a member of the monitor lizard family native to eastern Australia. A large lizard, it can reach 2 m in total length and 14 kg in weight. The lace monitor is considered to be a least-concern species according to the International Union for Conservation of Nature.
