Sphaerodactylus is a genus of geckos from the Americas that are distinguished from other Gekkota by their small size, by their round, rather than vertical, eye pupils, and by each digit terminating in a single, round adhesive pad or scale, from which their name is derived. All species in this genus are rather small, but two species, S. ariasae and S. parthenopion, are tiny, and – with a snout-vent length of about 1.6 cm (0.63 in) – the smallest reptiles in the world.

Ctenosaura acanthura, is a species of iguanid lizard found in eastern Mexico and extreme western Guatemala. The standardized English name is the Mexican spiny-tailed iguana. Confusingly however, an earlier edition of standardized names for Mexican herpetofauna called Ctenosaura acanthura the northeastern spinytailed iguana and applied the name Mexican spinytailed iguana to Ctenosaura pectinata, which was called the western spiny-tailed iguana in the second edition. It has also been referred to as the Veracruz spiny-tailed iguana and Gulf Coast spiny-tailed iguana. It is an egg laying species that is mostly herbivorous and a moderately large lizard commonly growing over one meter in total length.

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.
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.
