Шаблон:Short description Шаблон:Speciesbox
The common Puerto Rican ameiva or Puerto Rican ground lizard (Pholidoscelis exsul) is a species of lizard in the whiptail family.[1]
Geographic range
Ameiva exsul is found in coastal habitats of Puerto Rico, the United States Virgin Islands, and the British Virgin Islands. In Puerto Rico, the species is also found on the island of Isla Culebra, as well as in the Toro Negro State Forest.[2]
Description
Pholidoscelis exsul is a relatively large lizard; males can grow up to Шаблон:Convert. The maximum recorded male snout-to-vent length (SVL) is Шаблон:Convert, and the maximum recorded female SVL is Шаблон:Convert.
Color patterns vary widely among individuals, populations, and islands. Animals are predominantly colored gray, black, or brown, with large or small white dots along their backs. Dorsolateral stripes vary in number, length, and color. All individuals have a white or blue-white mottled stomach. The chin shield and throat patch are often light pink. Juveniles generally have a bright blue tail and more dots than stripes.
Biology
Puerto Rican ground lizards occur in habitat with open canopy structure and loose sandy soil in elevations between sea-level and Шаблон:Convert where the temperature is above 24 °C (75 °F) year-round.[3] Ground lizards forage for insects and small fruits and scavenge for dead animals or trash scraps in urban areas.
Reproduction
Sexually mature females of P. exsul bury 2–7 pink eggs approximately Шаблон:Convert below ground in loose soil in June–August. Juveniles may have a bright blue tail, like the closely related Pholidoscelis wetmorei (blue-tailed ground lizard), but they will lose the bright blue color in their tail with age. Individuals can live more than six years.
Threats
The main threat to P. exsul individuals is from other animals which eat ground lizards. Mammalian predators, all invasive species, include feral cats, dogs, and small Indian mongooses. Avian predators include American kestrels, Greater Antillean grackles, and pearly-eyed thrashers.
