Peringuey's leaf-toed gecko (Cryptactites peringueyi), also known commonly as the salt marsh gecko, is a species of lizard in the family Gekkonidae. The species is endemic to South Africa.
C. peringueyi is particularly tiny, not growing more than about 5 centimetres (2.0 in) in total length (including tail), making it the smallest lizard in the region, along with the striped dwarf leaf-toed gecko of the Western Cape.[citation needed] It has a red-brown body sometimes with thin, pale dark stripes.[citation needed]
Peringuey's leaf-toed gecko is nocturnal and lives in matted marsh vegetation where it lays two minute eggs in summer.[citation needed]
C. peringueyi is endemic to South Africa, being restricted to a few salt marshes in the Eastern Cape.[citation needed]
C. peringueyi was believed to be extinct for a long time, but a tiny population was rediscovered in 1992 by the estuary of the Kromme river.[citation needed]
