What is the name of the gecko in the picture?

The Tokay gecko is a nocturnal arboreal gecko in the genus 'Gekko', the true geckos. It is native to Asia and some Pacific Islands. This species occurs in northeast India, Bhutan, Nepal, and Bangladesh, throughout Southeast Asia, including Thailand, the Philippines, Malaysia and Indonesia, and to western New Guinea.

Its native habitat is rainforest, where it lives on trees and cliffs, and it also frequently adapts to rural human habitations, roaming walls and ceilings at night in search of insect prey. This is an introduced species in some areas outside its native range. It is established in Florida in the United States, Martinique, the islands of Belize. Increasing urbanization is reducing its range.

The Tokay gecko reaches a total length (including tail) of up to 30 cm (12 in). It is believed to be the third largest species of gecko, after the Giant leaf-tail gecko and New Caledonian giant gecko. It is cylindrical but somewhat flattened in body shape. The eyes have vertical pupils. The skin is soft to the touch and is generally gray with red speckles, but the animal can change the color of its skin to blend into the environment. The species is sexually dimorphic, the males being more brightly colored and slightly larger.

Tokay geckos are generally aggressive, territorial, and can inflict a strong bite. Females lay clutches of one or two hard-shelled eggs and guard them until they hatch. They feed on small insects, fruit and vegetation.
