Antimena is a chameleon that lives in dry forests in southwestern Madagascar. Males have a high casque on the head, and the body can change color for camouflage and communication.
The Antimena differs from other chameleons by a very high helmet on the head of males. It is important for nature because it eats insects and serves as prey for birds and snakes.
