About Anolis equestris Merrem, 1820
Adult knight anoles (Anolis equestris) have a total length of 13–20 inches (33–51 cm) including the tail, which is longer than the head-and-body section. Their weight ranges from 0.56–4.83 oz (16–137 g). Males grow larger than females: adult males have a snout–vent length of 3.9–7.5 in (10–19 cm), while adult females have a snout–vent length of 3.5–6.3 in (9–16 cm). Their base coloration is mostly bright green, with one yellow stripe along the side of the head and a second yellow stripe on the shoulder, and they are capable of limited color change. They have a pinkish-white dewlap, and juvenile knight anoles have light bands across their bodies. Knight anoles are native to Cuba, but have been widely introduced into South Florida, where they successfully reproduce and spread as an invasive species. They cannot tolerate cold temperatures; during winter freezes in Florida, they have been observed falling to the ground from tree canopies, a behavior also seen in green iguanas. Outside of specific cold weather aggregations, this species is solitary and highly territorial. In the relatively cold winters of highland regions in their native Cuba, a small number of individuals may rest next to one another. In Cuba, they occur from near sea level up to an altitude of 3,300 ft (1,000 m) across a broad variety of tree-containing habitats, including forest, mangrove, savanna, cultivated areas and gardens. In their introduced Florida range, they can even be found in trees along roads in Miami. Knight anoles are arboreal, and are mostly found high in trees on the trunk or canopy branches. They will descend to the ground to move between trees or for thermoregulation, and are occasionally seen on warm asphalt, rocks, or sidewalks during these trips.
