The panther chameleon (Furcifer pardalis) is a species of chameleon found in the eastern and northern parts of Madagascar in a tropical forest biome. Additionally, it has been introduced to Réunion and Mauritius.Male panther chameleons can grow up to 20 inches in length, with a typical length of around 17 in (45 cm). Females are smaller, at about half the size. In a form of sexual dimorphism, males are more vibrantly colored than the females. Coloration varies with location, and the different color patterns of panther chameleons are commonly referred to as 'locales', which are named after the geographical location in which they are found. Panther chameleons from the areas of Nosy Be, Ankify, and Ambanja are typically a vibrant blue, while those from Antsiranana and Sambava are red, green or orange. The areas of Maroantsetra and Tamatave yield primarily red specimens. Numerous other color phases, and patterns occur between and within regions. Females generally remain tan and brown with hints of pink, peach, or bright orange, no matter where they are found, but there are slight differences in patterns and colors among the different color phases.
