Reptiles of Puerto Rico and Surrounding Islands
The archipelago of Puerto Rico, including its satellite islands such as Culebra, Vieques, and Mona, hosts a diverse array of reptilian species. From the depths of the Caribbean Sea to the arid scrublands of the offshore islands, these reptiles occupy a wide variety of ecological niches, ranging from aquatic turtles and marine giants to specialized lizards and secretive fossorial snakes.
Key Facts
- Diverse Families: The region is home to a wide variety of families, including Emydidae (pond turtles), Cheloniidae (sea turtles), and Iguanidae (iguanas and anoles).
- Island Endemism: Many species, particularly within the Sphaerodactylus (dwarf gecko) and Anolis genera, are specific to individual islands like Mona or Desecheo.
- Marine Presence: Five distinct species of sea turtles, including the Leatherback and Green sea turtle, are found in the region.
- Specialized Adaptations: The fauna includes fossorial species such as worm lizards (Amphisbaenidae) and blindsnakes (Typhlopidae) adapted for underground life.
Turtles and Tortoises
The chelonians of the region are divided into freshwater, marine, and terrestrial groups. The Emydidae family includes the Puerto Rican slider (Trachemys stejnegeri stejnegeri) and the Red-eared slider, while the Testudinidae family represents land-dwelling tortoises, such as the South American yellow-footed tortoise.
Marine turtles are represented by two primary families: Dermochelyidae, containing the massive Leatherback sea turtle, and Cheloniidae, which includes the Loggerhead, Green, Hawksbill, and Olive ridley sea turtles.

Lizards exhibit remarkable diversity across the islands, with several families filling different roles in the ecosystem.
Geckos and Skinks
The Gekkota infraorder is particularly diverse, featuring numerous dwarf geckos (Sphaerodactylus) that are often restricted to specific islands, such as the Mona dwarf gecko and the Vieques dwarf gecko. The Scincidae family is represented by various skinks, including the Puerto Rican, Culebra, Mona, and Monito skinks.
Ameivas and Galliwasps
The Teiidae family includes the Greater Puerto Rican ameiva and the Blue-tailed ground lizard. Additionally, the Anguinidae family is represented by the Puerto Rican galliwasp (Diploglossus pleii).
Iguanas and Anoles
The Iguanidae family contains some of the most visible reptiles in the region. This includes a vast array of Anolis species, such as the Puerto Rican giant anole and the Emerald anole. Larger iguanas are also present, including the Puerto Rican iguana (Cyclura portoricensis) and the introduced Green iguana.
[ไม่มีภาพประกอบ]Snakes and Legless Reptiles
The region's serpents and legless reptiles range from large constrictors to tiny, sightless burrowers.
Boas and Colubrids
The Boidae family features the Puerto Rican boa, the Mona Island boa, and the Virgin Island tree boa. The Colubridae family includes the Puerto Rican racer and the Puerto Rican garden snake.
Fossorial Species
Specialized burrowing reptiles include the Amphisbaenidae (worm lizards), such as Baker's and Schmidt's worm lizards, and the Typhlopidae (blindsnakes), which include species like the Flat-headed blindsnake and the Mona blind snake.
