Cameroon Two-horned Mountain Chameleon Trioceros montium

The Cameroon Two-horned Mountain Chameleon, also called Cameroon Sailfin Cameleon, is endemic to high altitude forests of Cameroon in West Africa, a limited habitat.

Only the males have the horns, on the front of the face. The horns are used more for posturing and attracting females than for fighting, but the face is well-armoured just in case.

Males, shown, can grow to some 10 inches (25cm) long and females some 8 inches (20cm).
