Geckos
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the brille. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick their own brilles when t ...

Pygopodoidea
Pygopodoidea is a gecko superfamily and the only taxon in the gekkotan subclade Pygopodomorpha. The clade includes three Australasian families: Diplodactylidae (stone geckos), Carphodactylidae (knob-tailed geckos), and Pygopodidae (flap-footed geckos). Traditional gekkotan systematics had considered Diplodactylidae and Carphodactylidae as subfamilies of the family Gekkonidae, but recent molecular work have placed Pygopodidae within Gekkonidae making it paraphyletic. These analyses have shown support of Pygopodidae and Carphodactylidae being sister taxa, with Diplodactylidae occupying a basal position in Pygopodoidea. Below is a taxonomic list of pygopodoid genera in taxonomic order: *Pygopodomorpha (Vidal & Hedges, 2009) **Pygopodoidea (Gray, 1845) ***Diplodactylidae (Underwood, 1954) – Stone Geckos ****''Crenadactylus'' (Dixon & Kluge, 1964) – Clawless Gecko ****''Nebulifera'' (Oliver, Bauer, Greenbaum, Jackman & Hobbie, 2012) – Robust Velvet Gecko ****''Amalosia'' (Wells & ...

Gekkonidae
Gekkonidae (the common geckos) is the largest family of geckos, containing over 950 described species in 62 genera. The Gekkonidae contain many of the most widespread gecko species, including house geckos (''Hemidactylus''), the tokay gecko (''Gekko''), day geckos (''Phelsuma''), the mourning gecko (''Lepidodactylus''), and dtellas (''Gehyra''). Gekkonid geckos occur globally and are particularly diverse in tropical areas. Many species of these geckos exhibit an adhering ability to surfaces through Van der Waals forces utilizing intermolecular forces between molecules of their setae (foot hair) and molecules of the surface they are on. The genus ''Hemidactylus'' is one of the most species-rich and widely distributed of all reptile genera.Carranza, S., and E. Arnold.

Tokay Gecko
The tokay gecko (''Gekko gecko'') is a nocturnality, nocturnal arboreal locomotion, arboreal gecko in the genus ''Gekko'', the true geckos. It is native to Asia and some Pacific Islands. Etymology The word "tokay" is an onomatopoeia of the sound made by males of this species. The common and scientific names, as well as the family name Gekkonidae and the generic term "gecko" come from this species, too, from ''ge'kok'' in Javanese language, Javanese, corresponding to ''tokek'' in Malay language, Malay. Subspecies Two subspecies are currently recognized: *''G. g. gecko'' (Carl Linnaeus, Linnaeus, 1758) occurs in tropical Asia from northeastern India to eastern Indonesia. *''G. g. azhari'' (Robert Mertens, Mertens, 1955) is found only in Bangladesh. Distribution and habitat This species is found in northeast India, Bhutan, Nepal, and Bangladesh; throughout Southeast Asia, including Cambodia, Thailand, the Philippines, Malaysia, Vietnam and Indonesia; and toward western New Gu ...

Diplodactylidae
The Diplodactylidae are a Family (biology), family in the suborder Gekkota (geckos), with over 150 species in 25 Genus, genera. These geckos occur in Australia, New Zealand, and New Caledonia. Diplodactylids are the most ecologically diverse and widespread family of geckos in both Australia and New Caledonia, and are the only family of geckos found in New Zealand. Three diplodactylid genera (''Oedura'', ''Rhacodactylus'', and ''Hoplodactylus'') have recently been split into multiple new genera. In previous classifications, the family Diplodactylidae is equivalent to the subfamily Diplodactylinae. Habitat Like other geckos, Diplodactylidae often live in warm areas that are around the temperature of . They mostly live in rain forests, up in the trees for protection. However, they are also found in cooler climates such as those found in southern New Zealand, where they have been found to be active in temperatures ranging from 1.4 to 31.9C. Reproduction Viviparity is notable as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eublepharidae
The Eublepharidae are a family of geckos (Gekkota) consisting of 43 described species in 6 genera. They occur in Asia, Africa, North America, and Central America. Eublepharid geckos lack adhesive toepads and, unlike other geckos, have movable eyelids, thus commonly called eyelid geckos. Like other members of Gekkota, the Eublepharidae exhibits Autotomy, tail autotomy due to the fracture planes near their vent. A new tail will then grow in its place, usually lacking the original color and texture. The muscles in the old tail will continue to flex for up to 30 minutes after the drop to distract predators. Leopard geckos (''Eublepharis macularius'') and African fat-tailed geckos (''Hemitheconyx caudicinctus'') are popular pet lizards.

Carphodactylidae
The Carphodactylidae, informally known as the southern padless geckos, are a Family (biology), family of geckos, lizards in the infraorder Gekkota. The family consists of 34 described species in 7 Genus, genera, all of which are Endemism, endemic to Australia. They belong to the superfamily Pygopodoidea (or Diplodactyloidea), an ancient group of east Gondwanan geckos now only found in Australasia. Despite their well-developed limbs, Molecular phylogenetics, molecular phylogenies have demonstrated that Carphodactylidae is the sister group to Pygopodidae, a highly specialized family of legless lizards. Carphodactylids, despite being the most species-poor family of geckos, are still diverse in habits. 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 Lamella (surface anatomy), lamellae. Carphodactylids are relatively large by gecko standards; most are N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllodactylidae
The Phyllodactylidae are a family of geckos (Gekkota) consisting of 163 species in 10 genera, distributed throughout the New World, North Africa, Europe and the Middle East. The family was first delineated based on a molecular phylogenetic analysis in 2008, and all members possess a unique single codon deletion in the phosducin (''PDC'') gene. The phyllodactylid genus ''Bogertia'' has been recently synonymized with ''Phyllopezus''. The name of the family comes from the leaf shaped fingers.

Gold Dust Day Gecko
The gold dust day gecko (''Phelsuma laticauda'') is a diurnal species of gecko. It lives in northern Madagascar, the Comoro Islands, and the Mascarene Islands; it has also been introduced to Hawaii and other Pacific islands. It is primarily an arboreal species which can be found in tropical forests and may also associate with human dwellings. The gold dust day gecko feeds on insects and nectar. One subspecies is recognized (in addition to the nominate one): ''Phelsuma laticauda angularis ''Phelsuma laticauda angularis'' Mertens, 1964 is a diurnal subspecies of geckos.

Brille
The brille (also called the ocular scale, eye cap or spectacle) is the layer of transparent, immovable disc-shaped skin or scale covering the eyes of some animals for protection, especially in animals without eyelids. In squamate reptiles both the nictitating membrane and the eyelids have been suggested as the evolutionary origin of the brille, but embryonic studies supports the fusion of the dorsal and ventral eyelids. Brille means "spectacles" or " glasses" in German, Norwegian, and Danish. In snakes, there are no eyelids and the brille is clear and cannot be distinguished, except when the animal is becoming ready for ecdysis. At that time, it becomes cloudy and is visible as a cover over the eye. When the snake moults, the brille is also shed, generally inside out, as part of its skin. The brilles protect their eyes from dust and dirt and give them a "glassy-eyed" blank appearance. Snakes, flap-footed lizards, night lizards, and some skinks have brilles. All geckos except ...

Lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colour Vision
Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different frequencies independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of Photoreceptor cell, photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons ultimately leading to higher Cognition, cognitive functions in the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of the evolution of color vision within different animal taxon, taxa. In primates, color vision may have evolved under selective pressure for a variety of visual tasks including the foraging for nutritious young leaves, ripe fruit, and flowers, as well as detecting predator camo ...
