I'm surprised I haven't written this guide earlier, but better now than never!
One of the most common concerns new panther chameleon owners have is how to sex them. How do you know that the male you just paid more money for is actually a male? Well, the answer is relatively easy, you just have to get used to knowing what you're looking for. And the best way to help is to show lots of photos. Panther chameleons can be sexed right out of the egg. However, for the purpose of this blog I will show examples of panthers that are over a month old, so we can see what a baby that you just bought from a reptile show might look like, both in size, colors, and sexability.
Also, to quell some fears, please see this blog entry on how males mature differently: Two Panthers Growing Up - Photo Progression. Because not all males grow up the same way and "late bloomers" certainly exist. And for further reading see this other blog entry, Comparing Males and Females, which explains any differences in care, personality, and physiology.
PANTHERS AT 1.5 MONTHS OF AGE

This is going to be tough at first, and I want to show two tough babies for that reason. Look at the two babies. If you look closely, you will notice that on the male you can almost see a straight line from the stomach down and along the tail. This is because the base of the tail is thicker, to accommodate the male's sex organs as he matures. Where as in a female there is an indentation right after the vent/cloaca, because the tail base is much narrower. The tail is thus thinner, so it looks like much more gentle taper from the base to the tip. At this age do not focus on color (or lack there of), because it might be misleading.
