Male mali uromastyx reproductive parts.
First we thought there was something wrong, but when checking with the Herp Society we learned that those were his male reproductive parts or genitals. (Sorry Joey :)) Since there still don’t seem to be many images about this on the web I’m posting it.
And while I have your attention, please do not buy your reptile at a store. Instead, search the web for your local herp society and get your pet from them.
