Smallest organisms montane environments. There is relatively little data on size variation among individuals, growth from metamorphosis to adulthood or size variation among populations in these species. Additional studies and the discovery of further minute frog species are likely to change the rank order of this list. The dwarf gecko ("Sphaerodactylus ariasae") and the Virgin Islands dwarf sphaero ("S. parthenopion"), two geckos in the genus "Sphaerodactylus", are the world's smallest known reptile species and smallest lizard, with a snout-vent length of . A few "Brookesia" chameleons from Madagascar are equally small, with a reported snout-vent length of 15–18 millimetres for male dwarf
