Otocryptis Wiegmanni
''Otocryptis wiegmanni'', commonly called the brown-patched kangaroo lizard, Sri Lankan kangaroo lizard or Wiegmann's agama, is a small, ground-dwelling agamid lizard endemic to Sri Lanka. Etymology The specific name, ''wiegmanni'', is in honour of German herpetologist Arend Friedrich August Wiegmann.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Otocryptis wiegmanni'', p. 285). Habitat The preferred habitat of ''O. wiegmanni'' is the wet zone forests and lower mountain forests (rainfall >2000 mm), up to , of Sri Lanka. It is commonly seen in the leaf litter of shady rain forests. Defensive behaviour When perceiving danger, ''O. wiegmanni'' spurts away quickly on its large hind legs and might eventually climb up a sapling or tree. Diet ''O. wiegmanni'' feeds on small insects, grubs, and tender shoots. Deraniyagala PEP (1953). ''A Colored Atlas of some Vertebrat ...

Sitana
''Sitana'' is a genus of lizards, collectively known as the fan-throated lizards, from the family Agamidae. They are found in Nepal, India, Sri Lanka and Pakistan. The genus comprises fourteen species, including several recently discovered species, such as two new species from Sri Lanka. In 2016, a new genus named ''Sarada (lizard), Sarada'' was erected, consisting of one former ''Sitana'' species and two newly described ones. ''Sarada'' is the sister genus of ''Sitana''. Together they form a clade which sister group is ''Otocryptis''. Description ''Sitana'' are small to medium-sized lizards. They are ground dwellers, primarily eating insects but also mollusks and plant seeds. Males measure and females in snout–vent length. In an example of convergent evolution, males have prominent dewlaps, similar to anoles, which are used in communication during the breeding season. The dewlap may be small to large, depending on the species. Females lack the dewlap. Species There are four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884). After taking up gymnastics at Nuremberg, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agamidae
Agamidae is a family (biology), family of over 300 species of iguanian lizards indigenous to Africa, Asia, Australia, and a few in Southern Europe. Many species are commonly called dragons or dragon lizards. Overview phylogenetics, Phylogenetically, they may be sister to the Iguanidae, and have a similar appearance. Agamids usually have well-developed, strong legs. Their tails cannot be shed and regenerated like those of geckos (and several other families such as skinks), though a certain amount of regeneration is observed in some. Many agamid species are capable of limited change of their colours to regulate their body temperature. In some species, males are more brightly coloured than females, and colours play a part in signaling and reproductive behaviours. Although agamids generally inhabit warm environments, ranging from hot deserts to tropical rainforests, at least one species, the mountain dragon, is found in cooler regions. They are particularly diverse in Australia. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups 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 such as the forest-dwelling ''Draco'' lizards are able to glide. They are often 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 being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Sarada (lizard)
''Sarada'' is a genus of lizards in the family Agamidae. The common name large fan-throated lizards has been coined for this genus. It is the sister genus of ''Sitana''; together they form a group known as the fan-throated lizards. The genus, consisting of three species, was erected in 2016 on the basis of molecular phylogenetic studies from across peninsular India. The scientific name ''Sarada'' finds its origin in a Marathi word ( IAST: saraḍā) used to refer to Agamidae. All known members of this genus are restricted to two Indian states, Maharashtra and northern parts of Karnataka. Species The three species are listed here alphabetically: *'' Sarada darwini'' Deepak, Karanth, Dutta and Giri, 2016 – Darwin's large fan-throated lizard *'' Sarada deccanensis'' (Jerdon, 1870) – Deccan fan-throated lizard *''Sarada superba ''Sarada superba'', the superb large fan-throated lizard, is a species of agamid lizard found in Maharashtra, India.

Bipedal Locomotion
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning 'two feet' (from Latin ''bis'' 'double' and ''pes'' 'foot'). Types of bipedal movement include walking, running, and hopping. Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs (a group that includes crocodiles and dinosaurs) developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes (australopithecines, including humans) as well as various other extinct groups evolving the trait ...
