Anolis gingivinus

Anolis gingivinus, commonly referred to as the Anguilla Bank tree anole, is a species of lizard native to the islands of Anguilla, Saint Martin, and Saint Barthélemy in the Caribbean's Lesser Antilles. This anole is recognized for its distinctive appearance, featuring an olive to light grey body typically adorned with bold stripes running down its back, which gradually lighten along the flanks. A notable characteristic is its vivid orange chinflap, which is particularly prominent in males. Males can also display dark, marbled spotting on their bodies, adding to their unique coloration.

Distribution and Habitat

The Anguilla Bank tree anole is highly adaptable to various environments. It thrives in mesic to xeric habitats, including woodlands, coastal scrublands, and overgrown fields. This species demonstrates a capacity to live both in trees, as its common name suggests, and on the ground, showcasing its versatility in occupying different ecological niches. While widespread and common on its primary islands, its distribution can be localized in areas like Sint Maarten and St. Barthélemy, where it does not inhabit grassland environments.

Ecology and Behavior

Anolis gingivinus plays a role in the local ecosystem, though it is preyed upon by predators such as the American kestrel on Anguilla. Historically, it was the sole anole species on Anguilla until the introduction of Anolis carolinensis. On Saint Martin, it coexists with Anolis pogus, often occupying different microhabitats; Anolis gingivinus tends to favor higher and more exposed perches in areas where both species are present.
