English name: Tokay Gecko
Scientific name: Gekko gecko
Thai name: Tuk-kae Ban

Description: To 40 cm long. A huge gecko with a robust body. Grey to bluish-grey with bright red or orange spots. Most individuals also have pale to light blue spots, which sometimes can join together to form bands. Scales are granular, giving the skin a rough appearance, and tubercles form lines going down the body. Head is very broad and powerful. Tail is banded light and dark, vividly so in juveniles but fading in adults.

Similar Species: The large size and bright colors of the Tokay Gecko make it unmistakable in our area.

Habitat: Found in forests, parks, and near homes. Despite its large size it can be seen and heard throughout Bangkok. Is strictly arboreal, hiding in hollow trees and roofs during the day before becoming active on trees and walls at night.

Place in the ecosystem: Eats insects, rodents, smaller geckos and small snakes. Can be eaten by large snakes.

Danger to humans: Is large and strong enough to inflict a nasty bite, and should not be handled. Cannot do any real damage other than skin lacerations.

Conservation status and threats: Tokays used to be very common across Asia, but poachers have caught large numbers to sell in the pet trade or for Chinese traditional medicine. Fake claims that eating the dried tokay can cure HIV or diabetes has led to millions of them being caught and killed. Imagine millions of living creatures killed for a fraud! As a result the Tokay Gecko is now listed as endangered in China, their numbers have dropped in Thailand and Myanmar, and they are becoming a threatened species in the Philippines.

The Tokay Gecko has been introduced to several locations in the Americas, including Florida and Belize. Its large size and voracious appetite have led to concerns that it may be threatening local lizard populations.

Interesting facts: The Tokay Gecko gets its name from the recognizable “TOHK – AY” sound it makes from late afternoon through the night. In several parts of the city I have been unable to find the geckos due to their secretiveness and the heights they prefer, but can still hear their calls.

The Tokay Gecko is one of the largest species of gecko in the world, and its size sets it apart from other local geckos in a number of ways. It is the only gecko species in Bangkok to take vertebrates as prey, including young rodents, small snakes, and smaller species of gecko. While other geckos have many predators, the Tokay only has to worry about the larger snakes. And though the smaller geckos move quite quickly, a large Tokay Gecko can be amusing with its hefty “waddle” as it makes its way across a wall or tree branch.
