Tokay Gecko (Gekko gecko)

ReptileLizardAsia

Overview

The tokay gecko (Gekko gecko) is one of the largest and most striking geckos, a robust, big-headed lizard of South and Southeast Asia with bluish-grey skin spotted in orange and red and large, lidless, vertically slit eyes. It is named after its loud, distinctive call — a repeated “to-kay” or “gecko” sound that males give, especially at night, and which gives the whole gecko family its name.

Like other geckos, it has remarkable toe pads that let it run up smooth walls and across ceilings, but the tokay is also famous for being bold, vocal, and quick to deliver a strong, tenacious bite when handled.

Note: details here cover the tokay gecko as a species; treat general statements as approximate and verify against authoritative sources.

Habitat & Range

Tokay geckos are native to rainforests and rocky areas of South and Southeast Asia, but they adapt readily to human buildings and are often found on the walls and ceilings of houses, where they hunt insects drawn to lights. They shelter in tree hollows, rock crevices, and cracks in walls by day and emerge to hunt at night.

Diet

Tokay geckos are carnivores that eat mainly insects and other invertebrates — such as crickets, moths, cockroaches, and spiders — and large individuals can take small vertebrates, including other lizards, small snakes, frogs, and even small rodents. They are ambush and active hunters that snap up prey with a quick lunge.

Behavior

The tokay's toe pads are covered in millions of microscopic hairs (setae) that use tiny molecular forces to grip surfaces, letting the gecko cling to glass and run upside down — an ability that has inspired research into adhesives. Tokays are mostly nocturnal, territorial, and vocal, with males calling loudly to advertise their presence and warn off rivals. When threatened, a tokay opens its mouth wide, may lunge, and can deliver a firm, lasting bite. Like many geckos, it can shed its tail to escape and later regrow it.

Human Interaction & Conservation

Tokay geckos often live alongside people and help control household insects, and they are kept as pets (where legal). Unfortunately, huge numbers have been taken from the wild for the pet trade and especially for use in traditional medicine — based on unproven claims — which has put pressure on wild populations in parts of their range. They are otherwise harmless to people apart from a firm bite if handled. Consult authoritative sources for current status.
