The sphaerodactyline geckos are a physically small group of lizards found in the New World, in a range that includes South and Central America, the Caribbean and the south-eastern US. They are distinguished by their small size, poorly developed or absent toepads, and the single hard-shelled egg that they lay. There are five genera, of which the best known and largest are Sphaerodactylus and Gonatodes. Although attractive, the diminutive build of these geckos makes them less attractive to some would-be keepers due to the challenge of providing escape-proof quarters and small food items.
It should be noted that the subfamily Sphaerodactylinae is no longer recognised by many authorities.
