Geckos are unique among lizards in their vocalizations, making chirping sounds in social interactions with other geckos. Geckos are unusual in other respects as well. Many species have specialized toe pads that enable them to climb smooth vertical surfaces and even cross indoor ceilings with ease. These antics are well-known to people who live in warm regions of the world where several species of geckos make their home inside human habitations. These species (for example the House gecko) become part of the indoor menagerie and are seldom really discouraged because they feed on insect Pest (animal) pests. Most geckos are tan to dark grey, subtly patterned, and somewhat rubbery looking. Some species can change color to blend in with their surroundings or with temperature differences. However others can be brightly colored. Some species are parthenogenesis parthenogenic, the females capable of reproducing without copulating with a male. This improves the geckos' ability to spread to new islands. The toes of the gecko have attracted a lot of attention, as they adhere to a wide variety of surfaces, without the use of liquids or surface tension. Recent studies of the seta setae on gecko footpads demonstrates that the attractive forces that hold geckos to surfaces are van der Waals force van der Waals interactions between the finely divided setae and the surfaces themselves. That these kinds of interactions involve no liquids (or no gases) is important; in theory, a boot made of synthetic setae would adhere as easily to the surface of the International Space Station as it would to a living room wall. The family (biology) family Gekkonidae is divided into five different subfamilies, containing numerous different genus genera of gecko species. Many geckos are kept as pets and will eat various kinds of insects and sometimes fruit.

Common species of geckos

This species is found in houses throughout the tropics. This gecko may eat leafcutter ants. * '''Mediterranean gecko''', ''Hemidactylus turcicus''—residential and wild, introduced species (USA). * '''Leopard gecko''', ''Eublepharis macularius ''—The most common gecko kept as a pet is the leopard gecko, which does not have toe pads with setae, but rather claws. These enable it to more easily climb on rough surfaces like tree bark. This gecko cannot climb the glass of a terrarium. The leopard gecko tends to be docile and calm. This gecko can eat cockroach cockroaches, crickets, mealworms, waxworms, and superworms. *'''Mourning gecko''', ''Lepidodactylus lugubris''—This species is equally at home in the wild as in residential neighborhoods. Found in Hawaiian Islands Hawaii, it may have been an early Polynesian introduction. A parthenogenic species. *'''Stump-toed gecko''', ''Gehyra mutilata'' (=''Peropus mutilatus'')—This gecko can vary its color from very light to very dark to blend into a background. At home in the wild as well as in residential neighborhoods. * '''Tokay gecko''', ''Gekko gecko''—This is the lizard for which geckos were named. It is one of the relatively few lizards that vocalizes, and its mating call has variously been described as a loud ''gek-gek-gek-gekkkk'' or as ''tok-eh tok-eh''. The Tokay, an attractive but very aggressive species native to Southeast Asia, was in the past popular in the pet trade (apartment-dwellers in New York are sometimes advised by pet-shop owners to let Tokays run free to control cockroach cockroaches, though one might expect the vocalizations to be disconcerting!) and the species has naturalized in southern Florida and Hawaii. * '''Tree gecko''', ''Hemiphyllodactylus typus''—Tree geckos are forest dwellers. * '''New Caledonian crested gecko Crested Gecko''', ''Rhacodactylus ciliatus''— Until recently believed extinct. Gaining in popularity as a pet. * '''New Caledonian bumpy gecko Gargoyle Gecko''', ''Rhacodactylus auriculatus''— commonly known as the New Caledonian bumpy gecko or Gargoyle gecko. * '''New Caledonian Giant Gecko Leachianus Giant Gecko''', ''Rhacodactylus leachianus''— first described by Cuvier in 1829, is the largest of the Rhacodactylus geckos. * '''Crocodile or Moorish gecko''', ''Tarentola mauritanica''—Crocodile geckos are very strong and heavily built for their size usually growing up to 15.24 centimeter cm (6 inch in). They are commonly found in the Mediterranean region from southern France to Greece and North Africa northern Africa. Their most distinguishing characteristic is their pointed head and spiked skin with their tail resembling that of a crocodile's.
