Its nothing to do with caudo luring. They do that when they get excited. Whether its something new in the cage, or with prey items, or other monitors. It appears to be a state of excitement.

THey do far more with their tails then that, as well. They also hold their tails nearly strait up and do that wiggling thing, they do this to gain attention of other individual monitors. I have seen many lizards do this, including kimberlys, pilbaras, ackies, tristis, etc.

The oddest case of this was a pair of horned lizards that were courting and breeding in my yard. The female would belly down and lift he tail strait up in the air and wiggle it, the male would come over and place his head on here tail. Then she would move off and do it again and again. Until they copulated.

I did not get pics of that, as I was actually working on my truck. hahahahahaha. But I did take pics of another species of horned lizard that were courting like that. Cheers
