The geography of Puerto Rico consists of an archipelago located between the Caribbean Sea and the North Atlantic Ocean, east of the Dominican Republic or Hispaniola, west of the Virgin Islands and north of Venezuela. The main island of Puerto Rico is the smallest and most eastern of the Greater Antilles. With an area of 3,515 square miles (9,104 km2), it is the third largest island in the United States and the 82nd largest island in the world. Various smaller islands and cays, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos comprise the remainder of the archipelago with only Culebra and Vieques being inhabited year-round. Mona is uninhabited through large parts of the year except for employees of the Puerto Rico Department of Natural Resources.
Saint Croix is an island in the Caribbean Sea, and a county and constituent district of the United States Virgin Islands (USVI), an unincorporated territory of the United States.
The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. The oceanic trench, the deepest in the Atlantic, is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trough to the coast of Central America.
The culture of Puerto Rico is the result of a number of international and indigenous influences, both past and present. Modern cultural manifestations showcase the island's rich history and help to create an identity which is uniquely Puerto Rican - Taíno, Spanish, African, and North American.
Green Cay is an uninhabited island of the British Virgin Islands in the Caribbean. It sits between the eastern tip of Little Jost Van Dyke and Tortola. It is 14 acres (6 ha) in area.
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 island was sold by John and Jill Maynard in December 2014 to the owners of OtterBox, Curt and Nancy Richardson.
Sandy Cay is an uninhabited island of the British Virgin Islands in the Caribbean. It is located between Tortola and Jost Van Dyke. The island was owned by the Laurance Rockefeller Estate.

It measures less than half an acre in size, and consists entirely of a ring of sandy beach surrounding light foliage. It has the appearance of a classic paradise "desert island" and has been photographed for use in print medium in a number of advertising campaigns. Sandy Spit is a popular stop for day and term boat charters from Tortola, St. Thomas, and St. John. There are no moorings, but the sandy bottom is suitable for anchoring.

Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles, which 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 these crests, but these are smaller than those of the males. It 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 their throat, known as a dewlap, in order to show others how hip they are, and thus attract mates or intimidate rivals.
The Virgin Islands dwarf sphaero, Virgin Gorda least gecko, or Virgin Islands dwarf gecko is a species of gecko and also one of the smallest terrestrial vertebrates. It has only been found on three of the British Virgin Islands: Virgin Gorda, Tortola, and Moskito Island. It was discovered in 1964 and is suspected to be a close relative of Sphaerodactylus nicholsi, a dwarf sphaero from the nearby island of Puerto Rico. It shares its range with the big-scaled least gecko (S. macrolepis), which is found in leaf litter. Unlike this larger gecko, the Virgin Islands dwarf sphaero lives on drier hillsides, yet prefers moist microhabitats found under rocks because it lacks the adaptations necessary for preventing water loss, which is a significant problem due to its small body size.
Sphaerodactylus macrolepis, also known as the big-scaled dwarf gecko or the big-scaled least gecko, is a lizard of the Sphaerodactylus genus. It was first documented in 1859 in the US Virgin Islands, specifically, St. Croix. This diurnal species has since been spotted in other locations such as Puerto Rico with major populations in Culebra.
