This is a list of amphibians and reptiles found on Dominica, a Caribbean island-nation in the Lesser Antilles. Dominica is one of the few islands in that chain that has retained its original amphibian and reptile fauna over the last 200 years, and reptiles in particular form a significant part of its fauna. [1]
There are four species of amphibians on Dominica, all from the frog family Leptodactylidae. Three are native, and one, Eleutherodactylus amplinympha , is endemic to Dominica.
| Tropical frogs ( Leptodactylidae ) | |||
|---|---|---|---|
| Species | Common name(s) | Notes | Image |
| Eleutherodactylus amplinympha | Gounouj | Endangered. [2] Endemic. First described in 1994. Most abundant in transition zone between montane rainforest and elfin woodland, but range also extends over broader range of altitudes, coexisting with E. martinicensis. | |
| Eleutherodactylus johnstonei | Lesser Antillean whistling frog, coqui antillano, Johnstone's whistling frog | Least concern. Recently introduced. Widespread throughout the Lesser Antilles. |  |
| Eleutherodactylus martinicensis | Tink frog, Martinique robber frog | Near threatened. Regional endemic. Abundant in rain forest; uncommon in dry coastal forest. Local populations are being displaced by E. johnstonei along part of the west (Caribbean) coast. [3] |  |
| Leptodactylus fallax | Giant ditch frog, mountain chicken | Critically endangered. Regional endemic. Natural range on the western (Caribbean) side of Dominica from sea level to 400 m elevation. Populations are infected with chytridiomycosis and are in severe decline. Widely eaten in Dominica as a novelty food prior to its legal protection in 2002. [4] |  |
Two of the four extant orders of reptile are represented on Dominica: Squamata and Testudines. Including marine turtles and introduced species, there are a total of 19 confirmed species of reptiles.
Endemic reptile species include the Dominican anole (Anolis oculatus), the Dominican ground lizard (Ameiva fuscata) and the Dominica skink (Mabuya dominicana). The Dominican blind snake (Typhlops dominicanus or T. d. dominicanus) and the Dominican clouded boa ( Boa constrictor nebulosis ) may also be designated as endemic, though their status as distinct subspecies is unresolved.
| Tortoises ( Testudinidae ) | |||
|---|---|---|---|
| Species | Common name(s) | Notes | Image |
| Geochelone carbonaria | Red-footed tortoise | Likely recent introduction, though possibly as long ago as Amerindian settlement of Dominica. [5] Rarely seen in the wild. |  |

| Chelonia mydas | Green turtle | Endangered. Regularly seen in coastal waters; nests on both coasts (though mainly on northern beaches), primarily from June to October. |  |
| Eretmochelys imbricata | Hawksbill turtle | Critically endangered. Regularly seen in coastal waters; nests on both coasts (though mainly on northern beaches), primarily from May to October. |  |

Widespread and abundant in all areas below 900 m elevation. South Caribbean ecotype is being displaced by competition from invasive A. cristatellus. |  |
| Iguana delicatissima | Lesser Antillean iguana, West Indian iguana | Vulnerable. Regional endemic. Common on Dominica in certain areas on both east (Atlantic) and west (Caribbean) coasts; occasionally seen in rain forest. |  |

| Microteiids ( Gymnophthalmidae ) | |||
| Species | Common name(s) | Notes | Image |
| Gymnophthalmus underwoodi | Underwood's spectacled tegu | Very similar to G. pleii known to be extant on Dominica; variability of scale counts of collected specimens suggest G. underwoodi (or other Gymnophthalmus species) is also present. Presence confirmed 2008 by Turk, Wyszynski, Powell, and Henderson at Batali Beach [8] | |
| Gymnophthalmus pleii | Martinique spectacled tegu | Officially recorded only at Cabrits National Park and Dominica Botanical Gardens in Roseau, but likely more widespread, and probably with other Gymnophthalmus species present. [9] | |

Anolis oculatus, the Dominica anole, Dominican anole, eyed anole or zandoli, is a species of anole lizard. It is endemic to the Caribbean island of Dominica, where it is found in most environments. The species is found in a diverse range of color forms, which one herpetologist once classified as four subspecies, which most other scientists did not recognise because the forms gradually inter-grade with one another. Two later researchers have instead promoted the "ecotypes" concept, hypothesizing the color forms are maintained by the ecological conditions of the surrounding environment, despite being genetically indistinguishable. The morphology of some traits is subject to clinal variation, gradually changing from one side of the island to the other, or from sea level to the hilltops. The ground color ranges from pale tan or yellow to deep green or brown. It also has patterned markings that range from light-colored speckling to complex marbled patterns, and some populations also have large black-ringed "eye" spots on their flanks.
The Dominican ground lizard or Dominican ameiva is a species of lizard. It is endemic to the Caribbean island of Dominica, an island noted for its intact and abundant reptile population, where it is most commonly found in dry coastal woodland.
The Dominican blind snake or Dominican worm snake is a species of blind snake that is endemic to the Caribbean island-nation of Dominica, in the Lesser Antilles.
The fantastic least gecko, or fantastic sphaero is a species of gecko found in the Caribbean, on the islands of Dominica, Montserrat, and the Guadeloupe archipelago.
Vincent's least gecko is a species of lizard in the family Sphaerodactylidae. The species is endemic to the Caribbean.
Gymnophthalmus underwoodi, called commonly Underwood's spectacled tegu, is a species of microteiid lizard, which is found in South America and on certain Caribbean islands.
The little-scaled least gecko is a gecko species mainly found on the Caribbean island of Saint Lucia, where it was once thought to be endemic. It has falsely been recorded on St. Croix, Martinique, Monito Island, the British Virgin Islands, and Costa Rica, but does not exist there.
Sphaerodactylus parvus is a gecko endemic to the Anguilla Bank of islands in the Lesser Antilles, which comprises Anguilla, Saint Martin, and Saint Barthélemy. It was elevated to species level in 2001, formerly described as a subspecies of S. macrolepis.
The island least gecko is a species of gecko endemic to the Lesser Antilles in the Caribbean.
Anolis sabanus, the Saba anole or Saban anole, is a species of anole lizard that is endemic to the island of Saba, a Dutch municipality in the Caribbean Lesser Antilles.
The Antigua least gecko is a gecko endemic to the island nation of Antigua and Barbuda in the Caribbean Lesser Antilles, where it is found on both main islands.
The Guadeloupe blind snake or Guadeloupe worm snake is a species of blind snake that is endemic to Guadeloupe, located in the Caribbean Lesser Antilles. It is fairly widespread on the main islands of Basse-Terre and Grande-Terre, but is not recorded on the other Guadeloupean islands.
The Dominica skink is a species of skink found in Dominica. On Dominica, it can be confused with Gymnophthalmus pleii or juvenile Ameiva fuscata due to their similar appearance.
