I can try to help Scott but maybe this will mean nothing to you, most peoples can’t see a difference. I think it’s quit obvious, you should have no problem with argus.
I have not mistaken yet, maybe Dan’s water will be the first?

Thanks Jobi.I have gotten pretty good with savs just from head pics and looking at the nostrils and eye placement. Tailbases are easy. I have started looking closer at any pic I can find of water and mangroves and studying the jawline.
I am sure once my argus gets a little bigger, I will figure it out too. Right now I am thinking female due to the narrow shoulders and no noticable bulge at the tail base.
I will try to post pics of it soon. It is underground after downing 4 hoppers and 6 large roaches.

What to see and how to look!
Every detail’s are in these photos, forget about head body and coloration, just concentrate on the tail. Males and females monitors have different tail structure, it’s physiological and applies to all species, I use this as sex dimorphism. Look at the close up photos of the croc tails, don’t look for bulges, simply see how the females tail remains thicker way past the cloaca, this is because females use this part of there tails to store fat, they start storing fat in this part before any other part of there bodies, this difference can be seen at any size with practice. I suspect males don’t for convenience reasons, combat and recruitment for start, a more muscular tail is both stronger and flexible. In species witch needs to cross water, males will always have a higher rudder like tail (see photos), an obvious need to prowl territory.
This is not set in stone by any means, but it’s the best un-intrusive way I fund to sex monitors at first glance without manipulation. The more you see the better you get to be.
