1-4-2017 MIAMI, FLORIDA - BROWN ANOLE LIZARD (Anolis sagrei)


The Brown anole (Anolis sagrei) is a species of lizard native to Cuba and the Bahamas. It has been widely introduced elsewhere, via the importation and exportation of plants where the anole would lay eggs in the soil of the pots, and is now found in the United States. It has also been introduced to other Caribbean islands, Mexico, and Taiwan.

Brown anoles are normally a light brown color with darker brown to black markings on their back, and several tan to light color lines on their sides. Like other anoles, they can change color, in this case, a darker brown to black. Their dewlap ranges from yellow to orange-red. The tail has a ridge that travels all the way up to behind the head. Female Brown anoles can be distinguished from males by a light brown stripe that runs over their backs.


Brown anoles are native to Cuba and the Bahamas. Today, their range has extended as far as Georgia and parts of Mexico. These lizards typically avoid trees and prefer smaller plants and shrubs and are found in both urban and suburban areas.

Brown anoles are active during the day and are often seen basking on tree branches or rocks. When the weather is cold they hide under tree barks and inside rotten logs. They are social creatures. Female and male territories are separate but there are usually two or more female territories within one male territory. Males are very territorial and often fight with each other to protect their home range. Anoles use visual cues as their primary signaling mode. Males like to have high vantage points so they can overlook their territory in search of females to mate with or to spot other rival males that have encroached on their territory. They'll often bob their head up and down quickly before displaying their dewlap and will do sets of push-ups. When pursued or captured, Brown anoles can detach most of their tail. The piece that breaks off will continue to move, possibly distracting the predator and allowing the anole to escape. The lost tail will partially regrow. If provoked, Brown anoles will bite, urinate, and defecate. Also, some Brown anoles may do a short hiss if caught, injured, or fighting.

24-11-2015 SINGAPORE - BROWN ANOLE LIZARD (Anolis sagrei)


The brown anole (Anolis sagrei), also known commonly as the Cuban brown anole, or De la Sagra's anole, is a species of lizard in the family Dactyloidae. The species is native to Cuba and the Bahamas. It has been widely introduced elsewhere, via the importation and exportation of plants where the anole would lay eggs in the soil of the pots, and is now found in Florida and as far north in the United States as southern Georgia, Texas, Louisiana, Tennessee, Mississippi, Alabama, Hawaii, and Southern California.] It has also been introduced to other Caribbean islands, Mexico, and Taiwan.

This species is highly invasive. In its introduced range, it reaches exceptionally high population densities, is capable of expanding its range very quickly, and both outcompetes and consumes many species of native lizards, like the green anole. The brown anole's introduction into the United States in the early 1970s has altered the behavior and negatively affected populations of the native Carolina anole (Anolis carolinensis, also known as the green anole), which have since generally been relegated to the treetops.


The first record of the Anolis sagrei in Taiwan was in September 2000 at the Sanjiepu Township of Chiayi County. The source of the invasion was unknown. It was speculated that the egg from this animal is being hidden in potted plants heading to Taiwan and being introduced to Taiwan unintentionally. Wild groups are being discovered in the Ci Sing Tan Scenic Spot of the Hua-lian City in 2008. Monitoring removal plan was being carried out in 2009.

The brown anole is normally a light brown color with darker brown to black markings on its back, and several tan to light color lines on its sides. Like other anoles, it can change color, in this case a darker brown to black. Its dewlap ranges from yellow to orange-red.


Brown anoles are typically 5.0 to 8.5 inches long. The males can grow as large as their male Carolina anole counterparts, around 17.8–20.3 cm (7.0–8.0 in) long, with some individuals topping 22.9 cm (9.0 in). The females are also around the size of female Carolina anoles, which ranges from 7.6–15 cm (3.0–5.9 in). The male brown anole's head is smaller than that of the male Carolina anole.

The brown anole's tail has a ridge that travels all the way up to behind the head, a feature that the Carolina anole lacks. Female anolis lizards exhibit heritable polymorphism in their dorsal patterning. A study in Gainesville, Florida reported that one-third of A. sagrei females displayed a male-like chevron dorsal pattern, while other females had a striped dorsal pattern with continuous variation.
