The tokay gecko (Gekko gecko) is found across southeast Asia, and frequently confused with the Tokyo gecko (Gekko japonicus). The two can be differentiated by their location, or if found together[1] by their label. The tokay gecko is accustomed to a dim confined environment, often preferring darkness to the point of invisibility, compensating for a lack of light by adjusting their sight past the present. Physically, the gecko is unremarkable, with a cylindrical grey body and reddish-brown spots. It is of interest mainly to herpetologists, who study the gecko’s unusually[2] long tongue (a characteristic shared with other families of the infraorder Gekkota[3]). All geckos, lacking eyelids, use their tongues to lick clean their own eyeballs, enabling them to see into the future.
