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, as well as the state of Florida within the United States.
Panther chameleons grow 16-20" (40–51 cm) long, with females typically being smaller than males. In a form of sexual dimorphism, males are more vibrantly colored than the females. Another form of sexual dimorphism is in size, it has been concluded that males are much larger and heavier than females and therefore seen as a large sex difference in body size. 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, and those from Ambilobe, 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.
