'''''Takydromus''''' is a [[genus]] of [[lizard]]s, commonly called '''grass lizards''' or '''oriental racers'''.  [[Species]] of the genus ''Takydromus'' are [[Endemism|endemic]] to a large part of [[Asia]]. Members of this genus are noticeable because of their slender appearance and their agile movements. The word ''takydromus'' derives from [[Greek language|Greek]] ταχυδρόμος (''takhudromos''), "fast-running",<ref>[http://www.arbec.com.my/lizards/lacertidae/lacertidae.php ''Takydromus ''] {{Webarchive|url=https://web.archive.org/web/20111223045456/http://www.arbec.com.my/lizards/lacertidae/lacertidae.php |date=2011-12-23 }}, A Guide to the lizards of Borneo</ref><ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dtaxudro%2Fmos ταχυδρόμος], [[Henry Liddell|Henry George Liddell]], [[Robert Scott (philologist)|Robert Scott]], ''A Greek-English Lexicon'', on Perseus</ref> from ταχύς (''takhus''), "swift"<ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dtaxu%2Fs ταχύς], Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus</ref> + δρόμος (''dromos''), "course, race".<ref>[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Ddro%2Fmos δρόμος], Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', on Perseus</ref>

==Description==
Members of the genus ''Takydromus'' are extremely slender in appearance. The tail is about 2 to 5 times as long as the snout-vent length. The basic colour is normally brown, often with lateral stripes and dark spots. The dorsal scales are keeled and large. These keels form continuous longitudinal rows. The toes contain lamellae. The collar may be reduced or completely absent.{{citation needed|date=February 2020}}

==Distribution and habitat==
The lizard genus ''Takydromus'' is found in [[Japan]], in the [[Amur Oblast|Amur region]] of [[Russia]], and throughout entire eastern [[Asia]] to [[Indonesia]]. These lizards are mainly terrestrial although some species can be found on trees. Some members of this genus are found both on rocks and in relatively damp forests. Other species inhabit open grasslands.<ref>{{cite web| url = https://www.encyclopedia.com/environment/encyclopedias-almanacs-transcripts-and-maps/wall-lizards-rock-lizards-and-relatives-lacertidae| title = Wall Lizards, Rock Lizards, and Relatives (Lacertidae) {{!}} Encyclopedia.com}}</ref>
