Ashy gecko
Sphaerodactylus elegans·Gekkonidae
The Ashy gecko (Sphaerodactylus elegans) is a small, highly arboreal gecko native to Cuba and Hispaniola, known for its dark coloration adorned with numerous white spots. This species is an adept climber and has successfully established introduced populations in small islands of southernmost Florida. Distinct subspecies exhibit variations in coloration and patterning, with one being more vibrant and the other more muted.

About Ashy gecko
The Ashy gecko, scientifically known as Sphaerodactylus elegans, is a small gecko species native to the Caribbean islands of Cuba and Hispaniola. It is characterized by its dark body adorned with numerous white spots, and it is also noted for its climbing abilities. This species has successfully established introduced populations on small islands in southernmost Florida.
Taxonomy and Subspecies
Sphaerodactylus elegans is divided into two subspecies:
- Sphaerodactylus elegans elegans: This subspecies is native to Cuba, including Isla de la Juventud and various archipelagos. It has also been introduced to a small area of southernmost Florida.
- Sphaerodactylus elegans punctatissimus: This subspecies is found on Hispaniola, encompassing Haiti and the Dominican Republic, along with some of their satellite islands. It is generally more muted and earthy in tone compared to its Cuban counterpart.
Description
The Ashy gecko is a small reptile. The subspecies S. elegans elegans features granular scales and can have a snout length of up to 39 millimeters. Its coloration can vary, with tails ranging from red to blue, a green midsection, and thin horizontal black bands across its body. Its limbs are distinct in color and appear almost opaque relative to the rest of its body. Importantly, there are no observable color differences between males and females of this subspecies.
In contrast, S. elegans punctatissimus presents a more subdued coloration, described as earthy, and features a more pronounced spotted pattern.
Introduction to Florida
The presence of the Ashy gecko in Florida dates back to at least 1922, when it was first observed. It is believed to have been introduced from the West Indies, likely through the means of cargo shipments, a common method for species migration between islands. The subspecies S. elegans elegans specifically arrived in Monroe County, within the lower Florida Keys. Despite having a century to spread, its migration north has been limited by geographical barriers, confining it primarily to the lower Keys. It is one of only a few West Indian reptile and amphibian species to successfully colonize south Florida.
