The Tokay gecko, or Gekko gecko, is a large lizard recognized for its vibrant coloration and substantial size. Native to the tropical rainforests of Southeast Asia, it has also established populations in other parts of the world, including the United States.
Distinctive Traits and Native Habitat
As one of the largest gecko species, the Tokay can reach up to 16 inches, with 10-12 inches being common. Their bodies are a blue-gray color, covered in bright orange or red spots for camouflage. They have a large head with powerful jaws, a semi-prehensile tail that can be regrown, and specialized toe pads. These pads are covered in microscopic bristles called setae, allowing them to climb vertical surfaces with ease.
This gecko is native to the tropical rainforests of Asia and various Pacific Islands. As an arboreal species, it spends its life in trees and is primarily nocturnal. Its natural environment provides the high humidity and warm temperatures it requires. This adaptable species can also be found living near human habitations in its native range.
Vocalization and Temperament
The Tokay gecko is known for its loud vocalization. Males produce a sharp, barking call that sounds like “To-kay! To-kay!” to announce their territory, attract females, and warn off rivals. They can also produce other sounds like hisses and croaks when threatened.
These geckos have a defensive and assertive temperament. When confronted, a Tokay will stand its ground, gaping its mouth wide to display the interior and prepare for a bite. This is an innate defensive response. They are solitary animals, and males will aggressively defend their territory from other geckos.
Care and Handling as Pets
Due to their temperament, Tokay geckos are better as “display animals” than pets that are handled frequently. Their enclosure requires ample vertical space, and a tall 20-gallon tank is the minimum for a single adult. The habitat must have a secure top and a temperature gradient, with a basking area of 90–105°F and cooler areas around 80–85°F.
High humidity is another necessity, maintained through regular misting. Their diet consists mainly of insects like crickets, roaches, and grasshoppers, though larger adults may eat small rodents. Since they are territorial, Tokay geckos must be housed individually to prevent fighting.
Handling should be kept to a minimum to avoid stress and bites. A Tokay’s bite is powerful enough to break the skin, and they tend to latch on. If a bite occurs, do not pull the gecko off; instead, place it on a surface and wait for it to release its grip. As with all reptiles, proper hand washing after contact is important to prevent transmitting bacteria like Salmonella.
