The Tokay Gecko (Gekko gecko) is a fascinating species native to Southeast Asia, including countries such as Thailand, Malaysia, Indonesia, and the Philippines. Notable for their vibrant coloration, Tokay Geckos exhibit a striking pattern of blue or gray skin adorned with bright orange or red spots. This bold appearance serves as a deterrent to potential predators, signaling that the gecko is not an easy target. Tokay Geckos are among the largest gecko species, with some adults reaching up to 16 inches (40 cm) in length. Their robust build and powerful tails are well-adapted for climbing and maneuvering through their arboreal habitats, which range from tropical rainforests to the edges of agricultural fields.

In addition to their eye-catching looks, Tokay Geckos are known for their distinctive vocalizations. They produce a loud, repetitive "to-kay" call that can be heard during the mating season or when they are feeling threatened. This call, which gives them their common name, is used to establish territory and attract potential mates. Tokay Geckos are also known for their aggressive behavior, especially when confronted by humans or other animals. They have strong jaws and are capable of delivering a painful bite if provoked. Despite their intimidating demeanor, they play a crucial role in their ecosystems as voracious insectivores, helping control populations of pests.
