They have excellent sight, much much better then ours. They can hear well, but not sure how well. Between the two, sight is most dominate.

Yes, captive monitors and wild lizards can without question tell humans apart. Both rely of a safty factor, they become trusting a little at a time(most, not all) and that trust is easily broken. They seem to have a very keen sense of memory. You offend them, they will remember it, for years.

But they may devert that memory to a place or situation, and not you. Or even your shirt/blouse and not you. Something to keep in mind.

So yes, there is more to them then just being able to tell us apart.

They even sense trust and security in people they have never met.

A story, I met a couple who have a reptile park in the south of germany. They came to my house and wanted to see my monitors. I went up to one of my lacie cages and opened the door, much to my surprise, the lady reached in and kissed the big male on the lips. I thought she was gonner. Then I open the croc monitor cage, she did the same with the male croc. Hmmmmmmmmmmm simply amazing. As she left, both males leaned out of their cages and watched her leave. All I could say was, I will be danged. Both males really liked her. Funny but, its the female monitors that like me. The males alway want to play testosterone games. I guess thats as it should be. The males treat me like a male, and the females treat me like a male. PERFECT. This means they understand what sex you are, you can use that. Cheers
