I have 5 uromastyx lizards, four are Malis (ages 4,5,7,and 8) and one is an Ornate (age 2 1/2). I know that my Ornate is a male because of his color and how his femoral pores bulge out, but I am having troble finding the genders of my Malis. I have gone back and forth with deciding the gender by the pours.

My first question:
Is there another way, other than to look at the femoral pores, to tell the gender. Because I learned the term "hemipenal bulges", but I do not know what that means. The way it was motioned was that you had to see more of the underside of the tail to see the hemipenal bulges.

My second question:
All of my lizards have separate cages and when I do let them interacted with each other, under my supervision, I notice that some will bob their heads, some will roll over and flap their hands, and at other times they will run towards each other and try to bite one another, before I stop them. I am wondering if males and female uros share different breeding behavores? If so, maybe this will be the way I can tell their genders.


Thank you all very much,
Natalie and her uros.
