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.
Reptiles, in common parlance, are a group of tetrapods with an ectothermic ('cold-blooded') metabolism and amniotic development. Living reptiles comprise four orders: Testudines (turtles), Crocodilia (crocodilians), Squamata, and Rhynchocephalia. As of May 2023, about 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology.
Herpetology is the branch of zoology concerned with the study of amphibians and reptiles. Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology.
In biology, a common name of a taxon or organism is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case.
Sauropsida is a clade of amniotes, broadly equivalent to the class Reptilia, though typically used in a broader sense to include extinct stem-group relatives of modern reptiles. The most popular definition states that Sauropsida is the sister taxon to Synapsida, the other clade of amniotes which includes mammals as its only modern representatives. Although early synapsids have historically been referred to as "mammal-like reptiles", all synapsids are more closely related to mammals than to any modern reptile. Sauropsids, on the other hand, include all amniotes more closely related to modern reptiles than to mammals. This includes Aves (birds), which are now recognized as a subgroup of archosaurian reptiles despite originally being named as a separate class in Linnaean taxonomy.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Sauropterygia is an extinct taxon of diverse, aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Triassic before all except for the Plesiosauria became extinct at the end of that period. The plesiosaurs would continue to diversify until the end of the Mesozoic. Sauropterygians are united by a radical adaptation of their pectoral girdle, adapted to support powerful flipper strokes. Some later sauropterygians, such as the pliosaurs, developed a similar mechanism in their pelvis.
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks.
On 29 January 2010, the IUCN Red List of Threatened Species identified 5220 endangered species, subspecies and varieties, stocks and sub-populations.
Version 2014.2 of the IUCN Red List of Threatened Species identified 4574 Critically Endangered species, subspecies and varieties, stocks and subpopulations.

On 30 January 2010, the IUCN Red List of Threatened Species identified 9694 Vulnerable species, subspecies and varieties, stocks and sub-populations.
On 12 March 2010, the IUCN Red List of Threatened Species identified 3829 near threatened species, subspecies and varieties, stocks and sub-populations.
On 29 January 2010, the IUCN Red List of Threatened Species identified 6,702 data deficient species.
The Reptile Database is a scientific database that collects taxonomic information on all living reptile species. The database focuses on species and has entries for all currently recognized ~13,000 species and their subspecies, although there is usually a lag time of up to a few months before newly described species become available online. The database collects scientific and common names, synonyms, literature references, distribution information, type information, etymology, and other taxonomically relevant information.

Joseph Thomas Collins, Jr. was an American herpetologist. A graduate of the University of Cincinnati, Collins authored 27 books and over 300 articles on wildlife, of which about 250 were on amphibians and reptiles. He was the founder of the Center for North American Herpetology (CNAH). He died while studying amphibians and reptiles on St. George Island, Florida on 14 January 2012. "For 60 years I was obsessed with herpetology," Joe Collins claimed.
As of July 2021, the IUCN lists 14,033 animal species and 6,635 plant species as least concern. No least concern assessments have been made for taxa of other kingdoms.
