The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
Gargoyle geckos are primarily nocturnal. [1] [3] [8] They are an arboreal species, making their home in scrub forests. The female lays two eggs per clutch, which hatch 60 to 90 days after they are laid. The female can lay eight or nine clutches per year. On rare occasions, gargoyle geckos can reproduce asexually via parthenogenesis.
This gecko was 600 millimetres (24 inches) long, and it was likely endemic to New Caledonia, where it lived in native forests. [9] The smallest gecko, the Jaragua sphaero, is a mere 16 millimetres (0.63 inches) long, and was discovered in 2001 on a small island off the coast of Hispaniola. [10]
Rhacodactylus geckos are sexually dimorphic, with the males possessing larger preanal pores than the females as well as a distinct hemipenis pocket. Males tend to be stockier than females with the exception of R. auriculatus in which species the males are much slimmer than the females.
Currently there are about 40 extant families of Lacertilia.These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (Rhacodactylus leachianus), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (Varanus komodoensis), has a length up to 3 metres (10 ft ...

Palmate feet – Chilean flamingo. Totipalmate feet – blue-footed booby. Western grebe presenting a lobate foot. Lobate feet – a chick of the Eurasian coot. The great crested grebe. The feet in loons [2] and grebes [2] [7] are placed far at the rear of the body - a powerful accommodation to swimming underwater, [7] but a handicap for walking.
The generic name, Uroplatus, is a Latinization of two Greek words: "ourá" (οὐρά) meaning "tail" and "platys" (πλατύς) meaning "flat". Its specific name phantasticus is the Latin word for "imaginary", based upon the gecko's unique appearance, which led Belgian naturalist George Albert Boulenger to describe it as “mythical” in 1888.
