The Different Localities

Rhacodactylus leachianus is the largest living arboreal gecko and is native to New Caledonia. It exhibits remarkable variation in morphology, size, and behavior depending on its geographic origin. These differences have led breeders to distinguish various localities, meaning populations originating from specific islands or regions. When discussing Leachianus, the most important classification is the one that divides specimens into two main groups: GT (Grande Terre) and Insular. 

GT (Grande Terre) specimens originate from the main island of New Caledonia, known as Grande Terre. They are generally larger and more robust animals, with a heavier build and a slower growth rate compared to Insular forms. Their coloration tends to be more subdued, ranging from dark gray and black to olive green and brown. They are also known for having a more territorial temperament. Some of the best-known GT localities include Yaté, Poindimié, Mount Humboldt, Mt. Koghis, and Goro.

Insular specimens, on the other hand, come from the smaller islands surrounding Grande Terre. Although they belong to the same species, they evolved in isolated environments and developed distinctive characteristics. In general, Insular Leachianus are smaller than GTs, grow more quickly, and often display brighter and more striking coloration. They may feature pink, white, or other vivid patterns and color combinations. They are typically calmer in temperament and are often recommended for beginners. The most commonly kept Insular localities in captivity include Moro, Nuu Ana, Nuu Ami, Pine Island, Caanawa, Bayonnaise, and Brosse.
