Calling Geckos (Genus Gekko)

Gekko is a genus of geckos within the family Gekkonidae, infraorder Gekkota, and order Squamata. This genus includes some of the largest and most well-known gecko species in Asia, including several that are commonly encountered near human settlements.

Species of Gekko are primarily distributed throughout South, Southeast, and East Asia, with some species extending into parts of Oceania. They inhabit a wide variety of environments such as tropical rainforests, limestone karsts, rocky cliffs, agricultural lands, and urban areas.

Morphologically, members of this genus are generally medium to large-sized geckos with robust bodies, well-developed limbs, and broad heads. Many species possess strong adhesive toe pads that allow them to climb smooth vertical surfaces with ease. Their skin is often covered in small tubercles or granular scales, and coloration ranges from gray and brown to brightly patterned forms with spots or bands.

Most Gekko species are nocturnal and insectivorous, feeding on insects, spiders, and other small invertebrates. Larger species may also prey on small vertebrates such as lizards or rodents. They are known for their vocalizations, often producing loud clicking or barking sounds, especially during territorial displays or mating.

Reproduction is typically oviparous, with females laying two hard-shelled eggs per clutch in sheltered locations such as crevices, caves, or buildings. Due to their adaptability, several species have become synanthropic and are frequently found living in close association with humans.
