Squamata (/ skwæˈmeɪtə /, Latin squamatus, 'scaly, having scales') is the largest order of reptiles, comprising lizards and snakes. With over 11,991 species, [3] it is also the second-largest order of extant (living) vertebrates, after the perciform fish.

2024年7月9日 · Squamates are members of the largest reptilian order, Squamata. Characterized by horny epidermal scales and periodic molting, it is also the second-largest order of living …

Squamata (scaled reptiles) is the most diverse order of extant reptiles, comprised of the lizards and snakes and characterized a flexible jaw structure (movable quadrate bones) and having scales or shields rather than shells or secondary palates.

2019年8月16日 · Squamates (Squamata) are the most diverse of all the reptile groups, with approximately 7400 living species. Squamates include lizards, snakes, and worm lizards.

2013年4月29日 · We present a new large-scale phylogeny of squamate reptiles that should be a valuable resource for future comparative studies. We also present a revised classification of squamates at the family and subfamily level to bring the taxonomy more in line with the new phylogenetic hypothesis.

The Squamata, or the scaled reptiles, are the largest recent order of reptiles, comprising all lizards and snakes. With over 10,000 species, it is also the second-largest order of extant vertebrates, after the perciform fish, and roughly equal in number to the Saurischia (one of the two major groups of dinosaurs).

Squamates are the most diverse living clade of reptiles, including about 1,440 genera and 4,450 species of lizards plus 440 genera and 2,750 species of snakes. Although snakes are commonly considered to constitute their own group, they clearly have descended from lizards and are merely limbless lizards.

The Lepidosauria (/ ˌlɛpɪdoʊˈsɔːriə /, from Greek meaning scaled lizards) is a superorder of reptiles, containing the orders Squamata and Rhynchocephalia.

The Squamata is the sister group to the Rhynchocephalia (the Tuatara and extinct relatives), sharing a common ancestor around 250 million years ago at the start of the Mesozoic.

This comprehensive research article explores the taxonomy, anatomy, behavior, ecology, conservation, and significance of Squamata, providing a detailed understanding of these fascinating reptiles.
