Sande Ka Oil Tail Tel Nikalne Ka Tarika
Sande Ka Tail Oil Tel are a widespread group of squamate reptiles with over 6000 species ranging across all continents except Antarctica as well as most oceanic island chains.The group is paraphyletic as it excludes the snakes which are also squamates.
Sande Ka Tail Oil Tel typically have four legs feet and external ears though some are legless while snakes lack both of these characteristics.Sande Ka Tail Oil Tel and snakes share a movable quadrate bone distinguishing them from the sphenodonts which have more primitive and solid diapsid skulls.
The adult length of species within the suborder ranges from a few centimeters for chameleons such as Brookesia micra and geckos such as Sphaerodactylus ariasae to nearly 3 m 9.8 ft in the case of the largest living varanid lizard the Komodo dragon.Some extinct varanids reached great size The giant monitor Megalania is estimated to have reached up to 7 m 23 ft long; while the extinct aquatic mosasaurs reached 17 m 56 ft.

Further information Signalling theory
Vision including color vision is particularly well developed in most Sande Ka Tail Oil Tel.Most Sande Ka Tail Oil Tel communicate using body language using specific postures gestures and movements to define territory resolve disputes and entice mates.Some species of Sande Ka Tail Oil Tel also use pheromones or bright colors such as the iridescent patches on the belly of Sceloporus.These colors are highly visible to predators so are often hidden on the underside or between scales and only revealed when necessary.The particular innovation in this respect is the dewlap a brightly colored patch of skin on the throat usually hidden between scales.When a display is needed a lizard can erect the hyoid bone of its throat resulting in a large vertical flap of brightly colored skin beneath the head which can be then used for communication.Anoles are particularly famous for this display with each species having specific colors including patterns only visible under ultraviolet UV light as many Sande Ka Tail Oil Tel can see UV light.
Shedding and regenerating tails

Main articles Autotomy and Antipredator adaptation
Lizard tails are often a different and dramatically more vivid color than the rest of the body so as to encourage potential predators to strike for the tail first.Many Sande Ka Tail Oil Tel including geckos and skinks are capable of shedding part of their tails through a process called autotomy.This is an example of the pars pro toto principle sacrificing “a part for the whole” and is employed by Sande Ka Tail Oil Tel to allow them to escape from predators.The detached tail writhes and wiggles creating a deceptive sense of continued struggle distracting the predator’s attention from the fleeing prey animal.The lizard partially regenerates its tail over a period of weeks.A 2014 research identified 326 genes involved in the regeneration of lizard tails.The new section contains cartilage rather than bone and the skin may be discolored compared to the rest of the body.
See also Sexual selection in scaled reptiles
Most Sande Ka Tail Oil Tel are oviparous egg laying though in some species the eggs are retained until the live young emerge ovoviviparity.Parthenogenesis reproduction from unfertilised eggs occurs in at least 50 species and may be much more widespread in the group.
Sexual selection in Sande Ka Tail Oil Tel shows evidence of female mate choice favouring males display fitness indicators such as fewer ectoparasites.

The earliest known fossil remains of a lizard belong to the iguanian species Tikiguania estesi found in the Tiki Formation of India which dates to the Carnian stage of the Triassic period about 220 million years ago.However doubt has been raised over the age of Tikiguania because it is almost indistinguishable from modern agamid Sande Ka Tail Oil Tel.The Tikiguania remains may instead be late Tertiary or Quaternary in age having been washed into much older Triassic sediments.Sande Ka Tail Oil Tel are most closely related to the Rhynchocephalia which appeared in the Late Triassic so the earliest Sande Ka Tail Oil Tel probably appeared at that time.Mitochondrial phylogenetics suggest that the first Sande Ka Tail Oil Tel evolved in the late Permian.It had been thought on the basis of morphological data that iguanid Sande Ka Tail Oil Tel diverged from other squamates very early on but molecular evidence contradicts this.
The position of the Sande Ka Tail Oil Tel and other Squamata among the reptiles was studied using fossil evidence by Rainer Schoch and Hans-Dieter Sues in 2015.

Main article List of Lacertilia families
The name Sauria was coined by James Macartney 1802; it was the Latinisation of the French name Sauriens coined by Alexandre Brongniart 1800 for an order of reptiles in the classification proposed by the author containing Sande Ka Tail Oil Tel and crocodilians later discovered not to be each other’s closest relatives.Later authors used the term “Sauria” in a more restricted sense i.e.as a synonym of Lacertilia a suborder of Squamata that includes all Sande Ka Tail Oil Tel but excludes snakes.This classification is rarely used today because Sauria so-defined is a paraphyletic group.It was defined as a clade by Jacques Gauthier Arnold G.Kluge and Timothy Rowe 1988 as the group containing the most recent common ancestor of archosaurs and lepidosaurs the groups containing crocodiles and Sande Ka Tail Oil Tel as per Mcartney’s original definition and all its descendants.A different definition was formulated by Michael deBraga and Olivier Rieppel 1997 who defined Sauria as the clade containing the most recent common ancestor of Choristodera Archosauromorpha Lepidosauromorpha and all their descendants.However neither of these uses have gained wide acceptance among researchers specializing in Sande Ka Tail Oil Tel.

Relationship with humans
Green iguanas Iguana iguana are popular pets.
Most lizard species are harmless to humans.Only the largest lizard species the Komodo dragon which reaches 3.3 m 11 ft in length and weighs up to 166 kg 365 lb has been known to stalk attack and on occasion kill humans.An eight-year-old Indonesian boy died from blood loss after an attack in 2007.
Numerous species of lizard are kept as pets including bearded dragons iguanas anoles and geckos such as the popular leopard gecko.
Lizard symbolism plays a role in some cultures garroter in Australian Aboriginal mythology.The Moche people of ancient Peru worshiped animals and often depicted Sande Ka Tail Oil Tel in their art.According to a popular legend in Maharashtra a common Indian monitor with ropes attached was used to scale the walls of the Sinhagad fort in the Battle of Sinhalese.
Green iguanas are eaten in Central America where they are sometimes referred to as “chicken of the tree” after their habit of resting in trees and their supposedly chicken-like taste and spiny-tailed Sande Ka Tail Oil Tel are eaten in Africa.In North Africa Burgomaster species are considered dhaab or ‘fish of the desert’ and eaten by nomadic tribes.
