Squamata (/ s k w æ ˈ m eɪ t ə /, Latin squamatus, 'scaly, having scales') is the largest order of reptiles, comprising lizards and snakes.With over 12,162 species, [3] it is also the second-largest order of extant (living) vertebrates, after the perciform fish.
This template contains a phylogeny for squamate reptiles (lizards and snakes) based on 52 genes and 4162 species in the combined phylogenomic and supermatrix analysis by Zheng & Wiens (2016)) [1]. The template optionally uses {{ clade transclude }} as a wrapper that allows partial transclusion of parts of the phylogenetic tree selected by ...
The perentie (Varanus giganteus) is a species of monitor lizard. It is one of the largest living lizards on earth , after the Komodo dragon , Asian water monitor , and the Crocodile monitor . [ 3 ] [ 4 ] Found west of the Great Dividing Range in the arid areas of Australia, it is rarely seen, because of its shyness and the remoteness of much of ...
Snakes evolved from lizards, Beane said, because over time, some lizards adopted a lifestyle that didn’t require legs. Similarly, there are snakes with tiny limbs that they hardly ever use.
Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not ...
A hemipenis (pl.: hemipenes) is one of a pair of intromittent organs of male squamates (snakes and lizards). [1] [2] [3] Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like that in the human penis. They come in a variety of shapes, depending on species, with ornamentation such as ...
The scales may be ossified or tubercular, as in the case of lizards, or modified elaborately, as in the case of snakes. [1] The scales on the top of lizard and snake heads has also been called pileus, after the Latin word for cap, referring to the fact that these scales sit on the skull like a cap. [2]
Slender glass lizard (Ophisaurus attenuatus)Ophisaurus (from the Greek 'snake-lizard') is a genus of superficially snake-like legless lizards in the subfamily Anguinae.Known as joint snakes, glass snakes, or glass lizards, they are so-named because their tails are easily broken; like many lizards, they have the ability to deter predation by dropping off part of the tail, which can break into ...
