Conservation
Least Concern (IUCN). Highly successful invasive species often outcompeting native Green Anoles (Anolis carolinensis).
Physical Description
A small lizard with brown to grayish coloration. Features include a variable pattern of diamonds, triangles, or lines on the back. Males have a distinct orange-red dewlap with a yellow border. Large toe pads for climbing and a long tail.
Size & Dimensions
Specimen appears to be an adult around 5-8 inches. Typical range is 5 to 8.5 inches (12.7 to 21.6 cm), with males being significantly larger than females.
Habitat
Generalist species found in tropical and subtropical climates. Commonly inhabits urban gardens, parks, and disturbed secondary forests. Prefers vertical perches on tree trunks, walls, and fences at low to mid-elevations.
Diet & Feeding
Insectivorous; primarily eats small invertebrates like crickets, spiders, moths, and ants. Occasionally opportunistically hunts smaller lizards, including juveniles of its own species.
Reproduction
Oviparous. Females lay a single egg every 1-2 weeks during the breeding season (spring to autumn). Eggs are buried in moist soil or leaf litter.
Look-alikes
Green Anole (Anolis carolinensis), which can change to brown but maintains a white dewlap and sleeker snout. Also similar to other Anolis species in the Caribbean.
Conservation Status
Least Concern (IUCN). Highly successful invasive species often outcompeting native Green Anoles (Anolis carolinensis).
Cultural Significance
Commonly encountered in the exotic pet trade and widely used in biological research regarding island biogeography and evolution. Ecologically significant as an invasive species restructuring local food webs.
Notable Features
Distinguished by the ability to autotomize (drop) its tail to escape predators. Large specialized toe pads (lamellae) allow it to run up smooth vertical surfaces like glass.
