The modern form was probably borrowed into English and other European languages from Dutch gekko (1718). Contemporary English forms were chacco (1711) and jackoa (1724). The further origin is not quite clear. Some sources mention a supposed Malay gekok, gekoq, or gekop, which would be imitative of the gecko’s chirping sound. Another theory derives it from Acehnese gèh-gòh (“busy”).

- GECKOES constitute a family of lizards remarkable for the large number of species it contains. They are also remarkable for a number of other features: for the readiness with which they have taken to living in houses, for their voices, the structure of their feet, the variation in the shape of the tail and for their eyes. […] As with the more familiar lizards, geckoes have the ability to cast the tail, and counts show that in some species two out of every five individuals have cast the tail and regenerated a new one.

- Many lizards, including the British common and sand lizards of the family Lacertidae, clamber over rocks with great agility; none matches the geckoes, some of which can run up, down, or across vertical glass as easily as most beasts run on the flat, and indeed can happily traverse ceilings.

- The marvelous ability of geckos to run down trees, surefooted and head first, was first noted by Aristotle over two thousand years ago. However, Aristotle was not able to see the tiny hairs, called setae, that cover the toes of geckos and empower this feat. The setae are part of an adhesive system that allows geckos to maneuver on a wide variety of substrates, to run upside-down, and to arrest their falls. Geckos can run vertically at over 1 m/s and can carry over twice their body weight up smooth, vertical surfaces.

- By day, Golden-tailed Geckoes rest under curls of bark, the underside of branches, or in tree hollows but they seem to be fond of heat so these geckoes may even be in a situation where the sun shines on their daytime retreat all day. The Golden-tailed Gecko is an invertebrate-eater and by night its adhesive toe pads allow it to prowl the branches of Brigalow trees with ease, looking for small insects and spiders to capture.
