Puerto Rico, officially the Commonwealth of Puerto Rico, is a self-governing Caribbean archipelago and island organized as an unincorporated territory of the United States under the designation of commonwealth. Located about 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic in the Greater Antilles and the U.S. Virgin Islands in the Lesser Antilles, it consists of the eponymous main island and numerous smaller islands, including Vieques, Culebra, and Mona. With approximately 3.2 million residents, it is divided into 78 municipalities, of which the most populous is the capital municipality of San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates.
Territories of the United States are sub-national administrative divisions overseen by the federal government of the United States. The American territories differ from the U.S. states and Indian reservations as they are not sovereign entities. In contrast, each state has a sovereignty separate from that of the federal government and each federally recognized Native American tribe possesses limited tribal sovereignty as a "dependent sovereign nation". Territories are classified by incorporation and whether they have an "organized" government through an organic act passed by the Congress. American territories are under American sovereignty and, consequently, may be treated as part of the U.S. proper in some ways and not others. Unincorporated territories in particular are not considered to be integral parts of the U.S., and the U.S. Constitution applies only partially in those territories.

The Mona ground iguana is a critically endangered species of rock iguana, endemic to Mona Island, Puerto Rico. It is one of the island nation's few large land animals, and it is the largest endemic terrestrial lizard in the country, and one of the biggest rock iguanas within the Antilles. It was previously considered a subspecies of the rhinoceros iguana.
The yellow-shouldered blackbird, known in Puerto Rican Spanish as mariquita de Puerto Rico or capitán, is a species of blackbird endemic to Puerto Rico.

The Puerto Rican owl or múcaro común, formerly known as the Puerto Rican screech owl, is a mid-sized "typical owl" in subfamily Striginae. It is endemic to the archipelago of Puerto Rico though it formerly also inhabited the Virgin Islands.
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.
The Antillean fruit-eating bat is one of two leaf-nosed bat species belonging to the genus Brachyphylla. The species occurs in the Caribbean from Puerto Rico to St. Vincent and Barbados. Fossil specimens have also been recorded from New Providence, Bahamas.
The red-legged thrush is a species of bird in the family Turdidae. Native to the Caribbean, it is found in the Bahamas, Cayman Islands, Cuba, Dominica, Hispaniola and Puerto Rico. It formerly occurred on the Swan Islands, Honduras, but was extirpated there.
The red fruit bat or red fig-eating bat is a species of bat in the family Phyllostomidae, in the monotypic genus Stenoderma. It is found in Puerto Rico and the U.S. Virgin Islands.
Cardiocondyla is an Old World genus of ants in the subfamily Myrmicinae.
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.
Maricao State Forest is a state forest located in the eastern Cordillera Central mountains of Puerto Rico. It is commonly known as Monte del Estado due to the fact that it was one of the first forest reserves in Puerto Rico to be designated a state forest in its official name. With an area of 10,803 acres (43.72 km2), the Maricao State Forest is the largest of the 20 forestry units of the Puerto Rico state forest system.
Cardiocondyla elegans is an ant species in the genus Cardiocondyla found in the Mediterranean region.
Cardiocondyla minutior is a species of ant in the subfamily Myrmicinae.
Cardiocondyla nuda is a species of ant in the subfamily Myrmicinae. It is a widespread ant species, and not invasive in nature.
Vollenhovia emeryi is a species of ant in the family Formicidae.
Sphaerodactylus beattyi, also known commonly as the Saint Croix's sphaero, Beatty's least gecko, and the cotton ginner gecko, is a species of lizard in the family Sphaerodactylidae. The species is endemic to Saint Croix in the United States Virgin Islands. There are two recognized subspecies.
In ecology, a tramp species is an organism that has been spread globally by human activities. The term was coined by William Morton Wheeler in the bulletin of the American Museum of Natural History in 1906, used to describe ants that “have made their way as well known tramps or stow-aways [sic] to many islands". The term has since widened to include non-ant organisms, but remains most popular in myrmecology. Tramp species have been noted in multiple phyla spanning both animal and plant kingdoms, including but not limited to arthropods, mollusca, bryophytes, and pteridophytes. The term "tramp species" was popularized and given a more set definition by Luc Passera in his chapter of David F William's 1994 book Exotic Ants: Biology, Impact, And Control Of Introduced Species.
