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), arranged into lamellae that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
The gecko eye, therefore, modified its cone cells that increased in size into different types, both single and double. Three different photo-pigments have been retained, and are sensitive to ultraviolet, blue, and green. They also use a multifocal optical system that allows them to generate a sharp image for at least two different depths.
Gonatodes daudini, also known commonly as the Grenadines clawed gecko or the Union Island gecko, is a species of lizard in the family Sphaerodactylidae. The species is endemic to Union Island in Saint Vincent and the Grenadines .
It is worth noting here that the name "thick knee" of the members of the family Burhinidae is a misnomer because their heels are large. [2] [8] The chicks in the orders Coraciiformes and Piciformes have ankles covered by a patch of tough skins with tubercles known as the heel-pad. They use the heel-pad to shuffle inside the nest cavities or holes.
The Bynoe's gecko is a slender, long-tailed species which may grow to a total length (including tail) of 11–12 cm (4.3–4.7 in). It is covered with small scales which appear to be rough, but are soft to touch. [6] It has slim toes which end with strong claws, but unlike many other gecko species, it does not have expandable toe pads.
The common house gecko (Hemidactylus frenatus) is a gecko native to South and Southeast Asia as well as Near Oceania. It is also known as the Asian house gecko, Pacific house gecko, wall gecko, house lizard, tiktiki, chipkali [3] or moon lizard. These geckos are nocturnal; hiding during the day and foraging for insects at night.
[1] Consideration of Crenadactylus as a single species, Crenadactylus ocellatus, was also recognised by various authorities as three to four subspecies. [3] [6] However, molecular evidence revealed the phylogeny of the genus indicated numerous 'hidden species', and a revision in 2016 of accepted and new descriptions recognised a total of seven ...
Many have unusual, specialized tails with reduced rates of autotomy. They lack adhesive toepads and instead cling to bark or substrate with sharply curved claws and a limited array of lamellae. Carphodactylids are relatively large by gecko standards; most are nocturnal and all are oviparous, with a typical clutch size of two eggs. Unlike most ...
