Pygopodidae
Pygopodidae, commonly known as legless lizard, legless lizards, snake-lizards, or flap-footed lizards, is a Family (biology), family of squamates with reduced or absent limbs, and are a type of gecko. At least 35 species are placed in two subfamilies and eight Genus, genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea. Pygopodids have no fore limbs at all, but they do possess vestigial hind limbs in the form of small, flattened flaps. These may have some role in courtship and defensive behaviour, and may even aid in locomotion through vegetation. Some species are insectivore, insectivorous burrowing animals, but others are adapted to moving through dense Triodia (grass), spinifex or other vegetation.

Lialis Burtonis

Carphodactylidae
The Carphodactylidae, informally known as the southern padless geckos, are a family of geckos, lizards in the infraorder Gekkota. The family consists of 32 described species in 7 genera, all of which are 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 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 lamellae. Carphodactylids are relatively large by gecko standards; most are nocturnal and all are oviparous, with a typical clutch size of two eggs. Unlike mos ...

Paradelma
''Paradelma orientalis'', commonly known as the Brigalow scaly-foot or Queensland snake-lizard, is a species of legless lizard in the family Pygopodidae. It is endemic to Australia and is the only species in the monotypic genus ''Paradelma''. Cogger, H.G. (2018). ''Reptiles and Amphibians of Australia, Updated Seventh Edition''. Clayton South VIC, Australia: CSIRO Publishing. 1060 pp. (''Paradelma orientalis'', p. 402). As a member of the family Pygopodidae, ''Paradelma orientalis'' is a snake-like lizard with an elongated tail and no visible limbs apart from a pair of flaps equivalent to the hindlimbs of other lizards. Its body is dark brownish or greyish, with 18-20 rows of glossy scales and a subtle pale sheen. A patch of creamy coloration is present at the back of the head, followed by a black bar. Head scales are large and essentially symmetrical, and the two rows of ventral scales are wide and smooth. The nasal scales contact each other and a large ear hole is visible near ...

Diplodactylidae
The Diplodactylidae are a family in the suborder Gekkota (geckos), with over 150 species in 25 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 a trait unique to diploda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gekkota
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 throughout the world. 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 cornea. 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 t ...

Squamates
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most closely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legless Lizard
Legless lizard may refer to any of several groups of lizards that have independently lost limbs or reduced them to the point of being of no use in locomotion.Pough ''et al.'' 1992. Herpetology: Third Edition. Pearson Prentice Hall:Pearson Education, Inc., 2002. It is the common name for the family Pygopodidae. These lizards are often distinguishable from snakes on the basis of one or more of the following characteristics: possessing eyelids, possessing external ear openings, lack of broad belly scales, notched rather than forked tongue, having two more-or-less-equal lungs, and/or having a very long tail (while snakes have a long body and short tail). Many families of lizards have independently evolved limblessness or greatly reduced limbs (which are presumably non-functional in locomotion), including the following examples: * Anguidae – 102 species, of which 17 are limbless and in the genera ''Ophisaurus'', ''Pseudopus'' and '' Anguis'' from Eurasia and North America. * Cordyli ...
