Any of about 750 species of harmless but noisy lizard s in the family Gekkonidae: small, usually nocturnal reptiles that have soft skin, a short, stout body, a large head, and weak limbs often equipped with suction-padded digits.
The pads contain tiny hairlike projections that cling to surfaces, allowing geckos to climb absolutely smooth and vertical surfaces and even to run across ceilings. Most are 1–6 in. (3–15 cm) long, including the tail, and they are usually drably coloured, with gray, brown, or white predominating. They live in habitats ranging from deserts to rainforests in warm areas worldwide. Where kept as pets in houses or apartments, they are allowed to run free and eat undesirable insects.
