Species description
Geographical Origin and Habitat: The Cuban knight anole is endemic to the island of Cuba, where it widely inhabits warm and humid tropical forests, woodlands, orchards, and agricultural areas. It has also established feral breeding populations in southern Florida. This reptile is strictly arboreal, spending almost its entire life in the high canopies of mature trees, palms, and dense foliage, which provides it with excellent camouflage and a rich source of prey.
Taxonomy and Genetics: Classified within the family Dactyloidae (formerly placed in Polychrotidae or Iguanidae) and belongs to the genus Anolis. It is the largest species among all anoles. It displays a stable genetic profile across its native range, though localized morphs exist on Cuba. Evolutionarily, it features specialized subdigital lamellae on its toes for climbing smooth surfaces and eyes capable of independent movement.
Behavior and Habits: Strictly diurnal and arboreal, this lizard is highly territorial and display-oriented. Males will defend their territory aggressively against any rivals. When threatened, the knight anole displays a dramatic defensive posture: it expands its pink or yellow throat fan (dewlap), turns sideways to look larger, raises a dorsal crest along its neck, opens its mouth wide, and sibilates. If pushed, it will bite tenaciously.
Morphology: A large and heavy-bodied lizard, reaching an adult length of 35 to 50 centimeters, with the tail accounting for more than half of its total length. It has a bony, elongated head with a powerful jaw structure. The base body color is a vivid leaf green, which can change rapidly to dark brown when stressed, cold, or resting. It is distinguished by a white or yellow band below the eye and across the shoulder.
Care, breeding and tankmates
Terrarium Setup: Requires a very large, vertically oriented terrarium with minimum dimensions of 90x60x120 cm for a single adult. The enclosure must be densely planted with sturdy tropical foliage (such as Ficus, Pothos, and Dracaena) and furnished with a network of thick branches, hollow logs, and bamboo poles placed at various heights and angles to support climbing and basking.
Lighting and Heating: High-intensity UVB lighting (T5 10.0 bulbs) is mandatory to prevent bone disease and aid calcium metabolism. Create a thermal gradient using overhead halogen heating lamps to establish a basking spot of 32-35 °C, an ambient daytime temperature of 25-28 °C, and a night drop down to 20-22 °C. All heat sources must be controlled by a reliable thermostat.
Humidity and Hydration: Maintain high humidity levels between 70% and 80%. This should be achieved by misting the terrarium twice daily (automated misting systems are highly recommended). Knight anoles rarely drink from a standing water bowl; instead, they lick water droplets from leaves and branches. A water dish should still be present to help maintain ambient humidity.
Feeding and Supplementation: An aggressive carnivore. Their diet should consist of a variety of large gut-loaded insects, including dubia roaches, locusts, large crickets, hornworms, and silkworms. Adults can occasionally be fed pinky mice or small lizards. Dust insects with pure calcium at every feeding, and use calcium with vitamin D3 and a multivitamin supplement once a week.
Compatibility: Strictly solitary. Males are extremely aggressive and will fight to the death if housed together. Even heterosexual pairs can show dangerous aggression outside of breeding windows. Never house this species with smaller lizards, frogs, or geckos, as they will be viewed as prey items and eaten quickly.
Health and Common Diseases: The most common health issue in captivity is Metabolic Bone Disease (MBD), resulting from inadequate UVB light or calcium deficiency. They are also prone to respiratory infections caused by stagnant air and poor ventilation or low temperatures. Shedding problems (dysecdysis) can occur on their toes and tail if humidity is allowed to drop too low.

The catalog's scalar value is 19 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 19 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
