Threats to natives: Eats other arboreal lizards and frogs, and can potentially prey on small nestling birds and rodents (Bartlett and Bartlett 1999). It has even been observed eating a juvenile corn snake (Love 2000). Species Account: This large lizard from Southeast Asia can attain a total length of 30 cm (12 in). It is widely sold in the pet trade and is often released by persons to control cockroaches. In the subtropical climate of southern Florida, it is established in many residences and office complexes, where it is not restricted to the walls of buildings but can be found on trees, power poles, and other objects. It is primarily nocturnal but can sometimes be seen basking on cool, sunny mornings. The gray or blue-gray body has orange markings, which occur primarily as spots. The eyes and toe pads are large. Males often call loudly ("geck-o" or "to-kay") on warm nights. A cornered gecko will often aggressively bite an attacker and hold on tenaciously (Bartlett and Bartlett 1999).
