As the forum knows my passion is the knight anoles. So let me tell you how to tell the diffrence.
The male has a very large wide head that is very rough and bumpy and alot darker then the females also his tail just below the vent he will have his hemipenal bulges, if you press lighting with your fingers you can feel how "squishy" it is compared to the females firmer tail.
The female, has a habit of exteding her dewlap for exteded periods of time longer then a male will. She will have a smother head then the male. Also she will have white bands and in the older females the white bands will be either a really light white or a light blue... the bands go down the tail. On the back of theirs necks as they age are two oblong shapes that are differently colored in the pics you will notice the spots the 3 on the bottom and ontop of each other are females the one at the bottom is a very rough looking female the male is under then all at the top. Look closely at the females necks .. you can see the spots and notice the males.. eye ridges very large and pronouced until the females smoother head and face...if you wish to see closer pics of the male look up my name and theres plenty of "Mr.nall" Also on the females you can see the white bands still. If you wish to see pics of the bottoms of the "nalls" I will get some online for you> I hope this helps
