Gekko gecko, commonly known as the Tokay Gecko, is a large nocturnal gecko found in Southeast Asia. It has striking blue-gray skin with bright orange or red spots, and its loud, distinctive 'to-kay' call is often heard at night. Tokay Geckos are arboreal, primarily inhabiting rainforests, and they are known for their aggressive behavior and strong bite.

Gekko gecko, commonly known as the Tokay Gecko, is native to Southeast Asia. It is primarily found in countries such as Thailand, Vietnam, Cambodia, Laos, Myanmar, Malaysia, Indonesia, and the Philippines. Additionally, it has been introduced to other regions including parts of the United States such as Florida and Hawaii.

The Tokay Gecko typically inhabits tropical and subtropical environments. It thrives in warm, humid climates and is often found in rainforests, woodlands, and mangroves. It can also adapt to urban areas, residing in buildings and human dwellings.

Gekko gecko is primarily arboreal, meaning it spends most of its time in trees. It is a nocturnal species, actively hunting insects and small vertebrates during the night. The Tokay Gecko plays a role in controlling insect populations in its ecosystem. Its ability to climb smooth surfaces and its vocalizations, which are used for communication and territorial defense, are notable adaptations to its ecological niche.
