argus monitors are sexually dimorphic, that is there is a difference in size between males and females. the males are significanly larger than the females and more bulky appearing.
if you want info on care you can see my site's info on argus and read the "caresheet" which is more of a faq on monitors, not a all inclusive care guide, as there is no such thing to date.
argus are fun, active, inquisitive, and great feeders. if you have never had a monitor before, start with an ackie or croc monitor (damnit andrew, don't listen to that last part
