The knight anole (Anolis equestris) is a species of lizard in the Polychrotidae family, and the largest species of anole. Other common names include Cuban knight anole. It grows to a length of 13 to 20 in (33 to 51 cm) including the tail. A few specimens have reached up to 24 in (61 cm).
Knight anoles are native to Cuba, but have been widely introduced into South Florida, where they reproduce and spread readily. They cannot withstand freezing temperatures; in winter freezes in South Florida, they drop semiconscious from tree canopies. In its native Cuba, this large anole is called chipojo.
It is fiercely territorial. Aggressive to anything that enters its territory, the knight anole will face almost any intruder it perceives to be a threat (from a distance). During its display, a lizard will sit high on all fours, gape menacingly, turn green, and perhaps bob its head. The male will extend its dewlap (a reddish-white flap underneath the chin), and both females and males will "puff themselves up" with air.
In captivity, the anole's aggressiveness seems to lessen to a certain degree, if it is raised from the time of its birth and handled, it is common for it to become tame enough to be held. In communal terraria with other species of lizards, it rarely attacks smaller lizards unless the other reptile intrudes on its territory. It may be hand-fed with caution, since it has a strong bite and many small, sharp teeth. The mouth can harbor Salmonella bacteria and if a bite breaks the skin, an infection may occur.
Its main habitat is shady tree trunks, for these lizards are arboreal tree dwellers. The knight anole is a diurnal predator, though by warming itself on asphalt, rocks, or sidewalks at the end of the day, it may be able to remain active for a while into the night.
