geckos

Geckos are small to medium-sized lizards comprising the diverse group within the infraorder Gekkota, including many species commonly referred to as geckos. They inhabit warm climates across Africa, Asia, the Americas, Europe, and Oceania, with the greatest diversity in tropical regions and on islands. Most geckos are nocturnal or crepuscular and occupy a variety of habitats, from forests and deserts to urban areas.

A defining feature of many geckos is their specialized feet. Most species have expanded toe pads with microscopic setae that enable adhesion to smooth surfaces, allowing climbing on walls and ceilings. Some geckos, such as those in the family Eublepharidae, lack adhesive pads and rely on claws to grip rough surfaces. Many geckos can drop their tails to escape predators, and tail autotomy is often followed by regrowth, though the new tail may differ in shape or texture. Their skin colors and patterns provide camouflage, and some display vocalizations for communication.

Geckos are primarily insectivorous, feeding on crickets, beetles, and other small invertebrates, though larger species may hunt small vertebrates. Most geckos lay eggs, with eggs often deposited in secure crevices or under debris; a few species give birth to live young. They are preyed upon by birds, snakes, and mammals, and face threats from habitat loss and invasive species in some regions. Geckos are popular in the pet trade and play important roles in controlling insect populations.
