Sphaerodactylus

Sphaerodactylus is a genus of small geckos, commonly known as dwarf geckos or least geckos. They are the smallest living lizards in the world, with many species measuring less than an inch in length. These tiny reptiles are found in the Americas and the Caribbean, inhabiting a variety of environments from rainforests to arid scrublands.

The genus Sphaerodactylus is characterized by its granular scales, which give them a somewhat rough appearance. They possess large eyes, often with vertically slit pupils, and their toes are equipped with adhesive lamellae, allowing them to climb surfaces with ease. Most species are nocturnal, spending their days hidden in crevices, under bark, or in leaf litter. Their diet primarily consists of small invertebrates such as insects and spiders.

Reproduction in Sphaerodactylus typically involves the female laying one or two small, leathery eggs. These eggs are often deposited in concealed locations. The genus is diverse, with over 100 recognized species exhibiting variations in color patterns, size, and habitat preferences. Some species are brightly colored, while others are more cryptically patterned to blend in with their surroundings. Conservation status varies among species, with some facing threats due to habitat loss and other anthropogenic factors.
