The common Puerto Rican ameiva or Puerto Rican ground lizard (Pholidoscelis exsul) is a species of lizard in the whiptail family. [2]
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. [3]
Pholidoscelis exsul is a relatively large lizard; males can grow up to 85 cm (33 in). The maximum recorded male snout-to-vent length (SVL) is 201 mm (7.9 in), and the maximum recorded female SVL is 99 mm (3.9 in).
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.
Puerto Rican ground lizards occur in habitat with open canopy structure and loose sandy soil in elevations between sea-level and 600 m (2,000 ft) where the temperature is above 24 °C (75 °F) year-round. [4] Ground lizards forage for insects and small fruits and scavenge for dead animals or trash scraps in urban areas.
Sexually mature females of P. exsul bury 2-7 pink eggs approximately 100 mm (3.9 in) 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.
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.
The Puerto Rican spindalis is a bird endemic to the island of Puerto Rico, where it is commonly known as reina mora. The species is widely distributed throughout the island and is an important part of the Puerto Rican ecosystem because of its help in seed dispersal and plant reproduction. The Puerto Rican spindalis is the unofficial national bird of Puerto Rico.
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare.
Griswold's ameiva is a species of lizard in the family Teiidae. The species is endemic to Antigua and Barbuda, where it is found on both islands. It is also known as the Antiguan ameiva or the Antiguan ground lizard.
Amphisbaena caeca, commonly known as the Puerto Rican worm lizard or blind worm lizard, is a species of worm lizard endemic to Puerto Rico.

Other species of Amphisbaenids in the Caribbean include Amphisbaena bakeri, Amphisbaena fenestrata, Amphisbaena schmidti, Amphisbaena xera, and Cadea blanoides.

Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles. The species is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have this crest, but it is smaller than that of the males. The species is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on its throat, known as a dewlap, in order to show others how dominant it is, and thus attract mates or intimidate rivals.
Pholidoscelis maynardi, commonly known as the Great Inagua ameiva, Inagua ameiva, or Inagua blue-tailed lizard, is species of lizard, a member of the family Teiidae. The species is endemic to the Bahamas. Three subspecies have been described.

Pholidoscelis plei, known commonly as the Anguilla Bank ameiva or the Caribbean ameiva, is a species of lizard in the family Teiidae. The species is found on the Caribbean islands of Anguilla, Saint Martin, and Saint Barthélemy in the Lesser Antilles. Its coloration and markings vary between each island population. Two subspecies are recognized as being valid, including the nominotypical subspecies.
