Anolis parilis is a species of anole lizard native and endemic to the island of Hispaniola, which comprises the nations of Haiti and the Dominican Republic. It is a member of the diverse Anolis genus, known for its extensive radiation across the Caribbean and parts of the Americas.
Taxonomy
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Family: Dactyloidae (formerly Polychrotidae, often grouped under Iguanidae)
- Genus: Anolis
- Species: A. parilis
Anolis parilis is closely related to other green anole species, such as Anolis carolinensis (the American green anole) and Anolis porcatus (the Cuban green anole), often being grouped within the carolinensis species group due to shared morphological and ecological characteristics.
Description
Anolis parilis is a slender, medium-sized anole, typically reaching a snout-to-vent length (SVL) of 5-7 cm, with a tail often twice as long as its body. Its most distinctive feature is its ability to change color, ranging from bright green when active and warm to dull brown or gray, particularly when stressed, sleeping, or cold. Males possess a prominent, extensible dewlap, which is typically pinkish or reddish and used in courtship displays and territorial defense. Females generally lack a dewlap or have a much smaller, rudimentary one. Both sexes may exhibit faint lighter stripes or markings along their flanks, especially when in their brown phase.
Habitat and Distribution
As an endemic species, Anolis parilis is found exclusively on Hispaniola. It is an arboreal species, inhabiting a wide range of forested and semi-open habitats. This includes rainforests, dry forests, plantations, gardens, and urbanized areas where suitable vegetation is present. They are often observed perched on tree trunks, branches, shrubs, and even man-made structures like fences and building walls, typically at low to medium heights.
Behavior and Ecology
Anolis parilis is primarily diurnal and insectivorous. Its diet consists mainly of small invertebrates, such as insects, spiders, and other arthropods. Like other anoles, it is an active forager, employing a "sit-and-wait" predation strategy interspersed with active searching.
Males are territorial and will engage in head-bobbing displays and dewlap extensions to ward off rivals or attract mates. Reproduction is oviparous, with females laying single, soft-shelled eggs in moist soil or decaying leaf litter at regular intervals throughout the breeding season. The eggs typically hatch after several weeks, producing miniature versions of the adults.
Conservation Status
According to the International Union for Conservation of Nature (IUCN) Red List, Anolis parilis is classified as Least Concern (LC). This classification is due to its relatively wide distribution across Hispaniola, its adaptability to various habitats, including human-modified landscapes, and the absence of major widespread threats to its population. However, localized habitat degradation and introduced predators could pose risks in specific areas.
