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. Like all chameleons, panther chameleons exhibit a specialized
arrangement of toes. On each foot, the five toes are fused into a group of two and a group of three; these specialized feet allow the panther chameleon a tight grip on narrow branches. Each toe is equipped with a sharp claw to gain traction on surfaces such as bark when climbing. On the forelimbs, there are two toes on the outer (distal) side of each foot and three on the inside (medial). On the hind legs, the arrangement is reversed: two toes are fused medially and three distally. Panther chameleons have very long
tongues (sometimes longer than their own body length) which they are capable of
rapidly extending out of the mouth to capture prey, which is mostly terrestrial invertebrates and very rarely, plant material. Once the tip sticks to a prey item, it is drawn quickly back into the mouth, where the panther chameleon's strong jaws crush it and it is consumed. == Distribution ==
