The smallest iguana in the world is the dwarf or least gecko, scientific name Sphaerodactylus ariasae. This species of iguana is found primarily in Cuba and is the smallest of all lizards in the world, growing to a maximum length of just 2.25 inches (5.7 cm).
The dwarf or least gecko has a grey or brownish-grey body with black spots and a cream-colored underside. Its head is relatively small compared to its body, and it has short legs and a short, stubby tail. This species of iguana is nocturnal, preferring to hide in crevices and under logs during the day and forage for food at night.
The dwarf or least gecko is omnivorous, feeding on insects, spiders, and other invertebrates as well as fruits and flowers. In the wild, they are known to congregate in small groups, but they are not considered to be social animals.
These iguanas are not commonly kept as pets due to their small size and the difficulty of finding them in the wild. However, they are sometimes available in pet stores and can make good pets for someone who is willing to provide them with the right environment and care. They are active and curious, and they need a vivarium with plenty of foliage and hiding spots to feel secure.
The dwarf or least gecko is an important species for its environment, helping to keep insect populations in check and providing food for other animals. While it is not currently threatened as a species, its wild populations are decreasing due to habitat loss and other human activities. It is important to protect this species, as it is an important part of the ecosystem in its native habitats.
