When it comes to owning a green anole, the one question many new reptile owners have, is whether their green anole is male or female. Both males and females have their own unique characteristics that make them stand out, helping you sex your reptile with confidence.
A female green anole will be smaller than the males. Of course, if you only have the one anole, then trying to sex your reptile is not going to be easy based on size. Some of the females have a distinct line that runs along the spine to the end of the tail.
The green male anole can be an aggressive reptile or they can be less dominant. The less dominant species tend to be smaller than the alpha in the species. The less aggressive males are smaller, while male green anoles have a pink dewlap under the neck, which is rarely seen in females.
What to Look For
Male green anoles will take part in territorial displays. This can happen even when living on their own. This is when the reptile climbs onto something, extending their dewlap and bobbing their head. If your green anole does this from time to time, then you definitely have a male. Don't be fooled, females can also be very territorial, but they are less likely to fight.
A crest doesn't always develop on all male species. Some of the male green anoles will develop a crest which can be found along the top of their back, which is made to look larger when they are fighting.
Male green anoles have a thin flap of skin under the throat, better known as a dewlap. The dewlap is extended when defending territory or during mating rituals. The dewlap is a bright color, though in anoles it's not uncommon to see white or grey dewlaps. Females don't have dewlaps and those that do will be bland in color, not as brightly developed as the male.
Green anoles have the amazing ability to store sperm for up to seven months, which is why it's not uncommon for females to lay eggs after capture. Any anole laying eggs is female.
The male green anole will display a larger head than the female. In addition to this, males appear to have longer faces than females.
Male reptiles have reproductive organs, which are clearly visible, called postanal scales.. These create two bulged scales at the tail. Turn your reptile over, look right behind the vent and the postanal scales should be clearly visible. If you don't see bulges, then you are either dealing with a female or immature green anole.
Male and female green anoles are different sizes, but it's not always easy to tell them apart. Juveniles haven't developed secondary sexual characteristics and therefore younger anoles are all similar in size, even though you will see a slight difference at this time with males being slightly larger than the female. Anoles that reach eight inches or more can be identified as males, females don't seem to grow any further than five inches.
Quick Tips to Identify if Your Green Anole is Male or Female
