Uroplatus is a genus of geckos, commonly referred to as leaf-tail geckos, leaf-tailed geckos, or flat-tailed geckos.
They are endemic to Madagascar and its coastal islands, such as Nosy Be.
They are nocturnal, arboreal, insectivorous lizards - found exclusively in primary and secondary forest.
They range in total length (including tail) from about 30 cm (12 in) for U. giganteus to 10 cm (3.9 in) for U. ebenaui.
Larger species of Uroplatus are distinguished among geckos in having the largest number of marginal teeth among all living amniotes.
