Gecko \Geck"o\ (g[e^]k"[-o]), n.; pl. {Geckoes} (-[=o]z). [Cf.
   F. & G. gecko; -- so called from the sound which the animal
   utters.] (Zo["o]l.)
   Any lizard of the family {Geckonid[ae]}. The geckoes are
   small, carnivorous, mostly nocturnal animals with large eyes
   and vertical, elliptical pupils. Their toes are generally
   expanded, and furnished with adhesive disks, by which they
   can run over walls and ceilings. They are numerous in warm
   countries, and a few species are found in Europe and the
   United States. See {Wall gecko}, {Fanfoot}.
