Takydromus is a genusoflizards, commonly called grass lizardsororiental racers. Species of the genus Takydromus are 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 ταχυδρόμος (takhudromos), "fast-running",^[1][2] from ταχύς (takhus), "swift"^[3] + δρόμος (dromos), "course, race".^[4]

Description[edit]

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]}

Distribution and habitat[edit]

The lizard genus Takydromus is found in Japan, in the Amur regionofRussia, and throughout entire eastern AsiatoIndonesia. 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.^[5]

Reproduction[edit]

Females of speciesofTakydromus lay 1–10 eggs per clutch and up to 6 clutches per year.^{[citation needed]}
