Now, you know you want an anole lizard to be your next household pet.
But which one will be the best for you?
Before we jump into the comparison, let’s get to know the two species.
Green anoles (Anolis carolinensis) are tree-dwelling lizards. They are native to the Southeastern United States and can change color from green to brown.
Brown anoles (Anolis sagrei) dwell on the ground. They are native to Cuba and the Bahamas and can change from their original color to shades of gray and black.
Coming up next in this article, we’ll be taking a look at the similarities and differences between the two anole species in the following categories:
- Invasive species
- Male appearance
- Female appearance
- Male length
- Female length
- Male dewlap
- Female dewlap
- Reproductive season
- Egg laying
Let’s get comparing!
Green and brown anoles are native to different parts of the world.
The Southeastern United States is home to native green anoles (Anolis carolinensis). You will find the biggest population of native green anoles in the following states:
- North and South Carolina
Brown anoles (Anolis sagrei) are native to Cuba, the Bahamas, Jamaica, and the Cayman Islands.
Green anoles are native species of North America, whereas brown anoles are native to Cuba and the Bahamas.
Green and brown anoles have become invasive species in many countries around the world.
Green anoleshave been introduced to parts of the Pacific and the Caribbean. You will also find them in the Canary Islands and in Japan.
The Cuban brown anole (Anolis sagrei) has also been introduced to different countries it is not native to. These include parts of the United States, Mexico, the Caribbean, Taiwan, and Panama.
Invasive brown anoles are able to expand their range very quickly.
Brown anoles invade new environments with ease and quickly become the most dominant reptile species in their habitat. Because of this, many lands are trying to control their spread and view them as pests.
The Southeastern United States native green anole (Anolis carolinensis) is mainly arboreal, although it does also spend time in shrubs and on the ground. You will also find them on the edges of forests and in vines.
Brown anole lizards (Anolis sagrei) are ground-dwellers and like to live in small plants and shrubs. You are more likely to find them in urban areas.
These animals hide their eggs in the soil of plant pots, and thus they spread quickly to many parts of the world.
Green anoles live in trees, whereas brown anoles live on the ground.
These two lizards have similar average lifespans.
Both Anolis carolinensis and Anolis sagrei have lifespans that average 5 years.
However, in captivity, the green anole has the potential to live for up to 8 years.
Both of these reptiles have an average lifespan of 5 years.
Male green anoles and male brown anoles are distinct in appearance.
The male green anolecan change its color to any shade from brown to green. It has a long and pointed head and is 15% heavier than the female.
It has sticky adhesive pads on its feet that help it stick to even vertical surfaces.
The male brown anole is light brown and has dark brown or black markings on its back. The male's head is smaller than that of a male green anole's head.
They have strong gripping toepads, which help them adhere to challenging surfaces. They also have a dorsal crest.
Brown male anoles have smaller heads than green anoles, and their body colors are different.
Female green anoles and female brown anoles are also distinct in appearance.
The female green anole (Anolis carolinensis) can, like the male, change its color from green to brown. It has a long and pointed head and body and is 15% lighter than the male.
A female green anole has a white stripe running down its back.
Female brown anoles (Anolis sagrei) are the same color as the males. They are light brown and have dark brown or black markings on their backs.
Female green anoles and brown anoles have different body colors and markings. It is quite easy to tell the difference between the two.
The male green anole lizard and the male brown anole lizard vary in length.
Green anole males (Anolis carolinensis) usually measure between 5 and 8 inches in length. They are always bigger than the females.
Brown anole males usually measure 7 to 8 inches in length, but some can even grow up to 9 inches long. They are also always bigger than the females.
Brown anole males are slightly bigger than green anole males.
Green female anoles and brown female anoles are usually the same lengths.
Like female green anoles, female brown anoles measure 3 to 6 inches in length.
Female green anoles are the same size as female brown anoles.
The male brown anole’s dewlap and the male green anole’s dewlap are different in color.
The male green anole has a bright pink to orange color throat fan (dewlap) that is 3 times bigger than the females’. He displays it often and especially when trying to attract females and in an attempt to ward off other males.
Male brown anoles (Anolis sagrei) have dark red to yellow throat fans (dewlaps), which they display during courtship. It is bigger than the females’ and more often on display.
Male brown and green lizards have different color dewlaps.
The female anole lizard species do not display their dewlaps as often as the males do.
The female green anole has a lighter colored dewlap than the male. It is also 3 times smaller than the male’s dewlap.
The female brown anole has a red to yellow dewlap, but it is smaller than the males’.
Female anole lizards have different color dewlaps.
The brown and the green anole lizard have different diets.
The green southeastern US native lizard will eat the following:
- Insects. These include small crickets, mealworms, small roaches, and other invertebrates.
- Grains and seeds
The brown Cuban lizard will eat the following:
- Insects. These include crickets, butterflies, ants, and other species of insects.
- Other small lizards. These include eggs, hatchlings, green anoles, smaller anoles, skinks, and geckos.
- Their own species, their own shed skin, and their own tails
- Small fish
Brown lizards have a wider diet which includes eating green anoles. Because of this, the introduced brown anole quickly becomes the most dominant or the only species of small reptile in the habitat.
Green and brown anoles have the same mating seasons.
Mating season for these lizards begins in early April. It finishes in late September.
Brown and green lizards have the same mating season from April to September.

Green vs Brown Anole FAQs
Have you still got lots of unanswered questions you want answered?
Then check out the following list of brown vs green anole FAQs.
Do Brown Anoles Eat Green Anoles?
Yes, brown anoles do eat green anoles. When this species comes into a new environment, it quickly takes over and becomes the most dominant reptile

Can Brown and Green Anoles Mate?
No, brown and green anoles are different species, so they cannot mate. There are no hybrids between the two species.
Another reason they cannot mate is because the two do not get on together and cannot cohabit. When brown anoles come into a green anole’s territory, they become very aggressive toward them and quickly take over.

Why Are Some Anoles Green and Some Brown?
Green anoles can change colors. They can vary from green to brown.
This anole species will change color depending on its mood, the temperature in its environment, and even its humidity. Your green anole may also change color to brown if it is not feeling well.
Brown anoles, on the other hand, are always a shade of brown, gray, or black. They change color according to their mood, but they cannot turn green.
Why Is My Green Anole Brown?
Your green anole will change color for a number of reasons. Here are some of them.

If your pet looks unwell, take it to the vet immediately. Have it checked routinely by the vet, at least once a year.
Do Green and Brown Anoles Live Together?
No, brown and green anoles cannot live together in the same enclosure. Although they have almost the same habitat requirements, they do not get on well.
A Cuban anole will bully a green anole and will also eat it. It will also eat a green anole’s eggs and its hatchlings.
They will also bully them out of the best UVB light basking spots, and your green anoles will suffer.
In the wild, green anoles that used to live in tree trunks are forced to climb to higher branches where their enemies are reluctant to try to reach them.
Green Anole vs Brown Anole Which Is Invasive?
Both species of anoles are invasive to different parts of the world.
Anolis carolinensis is invasive to the following places:

- Islands in the Caribbean
- Taiwan (where they are damaging the country’s ecosystem)
Part of the natural animal behavior of this species is to hide eggs in the soil of potted plants. These eggs are extremely difficult to spot.
The plants are then taken to countries around the world. This results in this exotic lizard spreading far and wide from its native range.
